ZTE Silent Mode
An emerging Chinese telecoms giant is growing steadily and stealthily
October 16, 2008

I
n the last quarter of 2007 there
were three new entrants in the
top ten list of mobile-phone
makers. Most people know two
of them—Apple, maker of the iPhone,
and Research in Motion (RIM), maker
of the BlackBerry—but not the third:
ZTE of China. Its worldwide market
share went from 0.4% at the start of
2007 to 1.2% in the second quarter
of 2008, according to Gartner, a
consultancy. Last month it sold its 100
millionth phone. Its goal is to become
the third-biggest handset-maker,
behind Nokia and Samsung (it now
lies in sixth place). Yet ZTE is easy
to overlook, because of its distinctive
business model.
November 2008 ZTE TECHNOLOGIES
Founded in 1985, ZTE chiefly makes
networking gear, rather than phones.
With prices for comparable products
25-90% less than those of its western
competitors, ZTE has customers in
over 60 countries. As Alcatel-Lucent,
Nortel and other established telecomsequipment makers have suffered, ZTE
has thrived. Its revenues and profits
increased by more than 50% in 2007.
This year growth is also likely to be
strong, for two reasons.
Export sales, which account for
around two-thirds of revenues, continue
to grow as poor countries expand the
range and capacity of their mobilephone networks. On October 13th,
2008, for example, ZTE announced a
$400m contract to provide equipment
for a new network in India. At the same
time ZTE will benefit from one of the
largest telecoms projects in history:
the construction of China’s muchdelayed “third generation” (3G) mobile
networks.
Behind ZTE’s emergence are the
usual factors that have come to be
associated with China’s economic rise,
with a few twists. ZTE has benefited
from the thousands of inexpensive and
well-trained engineers coming out of
China’s universities, many of whom
are deployed at short notice to work on
large projects in some of the world’s
most difficult places. More fuzzy,
but still important, has been ZTE’s
ability to use help from the Chinese
government to arrange cheap financing
for its global customers, which often
lack capital.
Beyond these broader factors, ZTE
has done a good job of understanding
how to pursue a low-cost strategy,
and there is far more to it than merely
producing cheap products. “ZTE is a
strong technology company, but of a
particular sort,” says James Liang, an
analyst with Citigroup. ZTE focuses
on making equipment that is cheap,
reliable and unobtrusive.
In developed markets, makers of
elaborate handsets such as Nokia,
RIM and Apple have strong brands
and fiercely loyal customers. This is a
mixed blessing for network operators:
offering a snazzy new handset can
help them attract customers, but
many users are more loyal to their
handset-maker than to their operator.
ZTE, by contrast, keeps itself in the
background. It supplies handsets on
a “white label” basis to operators,
which then sell them under their own
brands. The name ZTE is nowhere
to be seen. In keeping with its roots
as a network-equipment supplier, it
sees operators, not consumers, as its
customers.
ZTE moved into the handset market
in 2002, and handsets accounted for
22% of its revenue last year; it expects
this figure to reach 50% by 2012. ZTE
does make some advanced handsets,
but its strength is in combining low
cost with a willingness to customise
handsets for the operators. For
Australia’s Telstra, for example, it
produced a “country phone”, with a
pull-out antenna, which suits people
outside cities who need highly sensitive
receivers. Although ZTE supplies
phones to big names such as Vodafone
and Telefónica, most of its customers
are in the developing world, where
overall handset sales are growing by
16% a year. ZTE’s steady but stealthy
rise reflects how much of the growth
in telecoms is at the bottom of the
economic pyramid.

ZTE Continues Its CDMA Success Story
—An interview with Ms. Li Jian, General Manager of ZTE’s CDMA products
I
Li Jian joined ZTE in 1997 and is now the general manager
of ZTE’s CDMA products. She was the former chief of ZTE’s
research institute in Nanjing and also the former general
manager of GoTa products. During her term as the head of
GoTa products, Ms. Li made outstanding contributions in such
aspects as international marketing, standardization, the granting
of IPR, completion of industry chain, terminal diversification and
performance enhancement.
November 2008 ZTE TECHNOLOGIES
n a report published early this year,
Yankee, a renowned American
consulting company, chose ZTE
as the most competitive CDMA
product supplier in Asia Pacific, Europe,
the Middle East and Africa. ZTE tops
in four evaluation factors including
existing installed base, price, technology
and product portfolio.
According to a report by another
American consulting firm EJL Wireless
this August, ZTE dominated the CDMA
market in Q2, capturing 10 of the 12
new CDMA contracts.
After strenuous efforts of eight years,
ZTE has made great achievements in
the CDMA field. ZTE has deployed 150
million lines of CDMA equipment, and
it has remained No. 1 in CDMA base
station shipment for several consecutive
years. With a 1/3 market occupancy rate,
ZTE tops the CDMA equipment market
in China.
With a full-fledged CDMA product
line and solid market foundation, ZTE
is now embracing the opportunity from
the reshuffling of China’s telecom
industry. What preparations will ZTE
make for this historic opportunity?
How will ZTE continue its CDMA
success story? With these questions in
mind, ZTE Technologies’ journalist
made an exclusive interview with
Li Jian, General Manager of CDMA
products of ZTE.
Journalist: ZTE has made impressive
achievements in the CDMA field and
has won the biggest share in the world’s
newly-added market for two consecutive
years. Could you please give us an
introduction of the market scale and
global applications of ZTE’s CDMA
products? What advantages do ZTE’s
CDMA products have to make such
achievements?
Li Jian: After eight years of strenuous
yet effective marketing efforts, ZTE’s
CDMA products have been adopted by
120 operators in more than 70 countries
with a total capacity of over 150 million
lines, making ZTE one of the leading
CDMA suppliers in the world. For two
consecutive years, 2006-2007, ZTE
has been ranked as the No. 1 leader in
CDMA base station shipment globally.
With successful CDMA network
applications in China, India and
Indonesia, ZTE has established a
“golden CDMA triangle” in Asia
Pacific. Moreover, it has made major
breakthroughs in high-end mobile
communications markets, including the
United States and Europe. In China,
ZTE tops the CDMA market with a
34% market share. In India, ZTE won
the biggest share of the newly added
CDMA market in 2007 and is now a
major CDMA supplier for Reliance, Tata
Teleservices and BSNL. In Indonesia,
ZTE is also a mainstream supplier for
many operators, including Telkom,
Indosat, Smart Telecom and Mobile-8.
These achievements are mainly
attributed to our defined product
orientation and brand position. As far as
four years ago, when ZTE just joined the
world’s first CDMA camp, we set a grand
objective of “becoming the No.1 leader in
CDMA base station shipment within three
years; making ZTE’s CDMA the No. 1
brand name in the world”.
Guided by this strategic objective,
we have been constantly making
technical innovations. While stabilizing
and upgrading the performance of our
first-generation CDMA products, we
launched a series of All-IP CDMA2000
products and systems, three years
ahead of the industry. These three
years witnessed ZTE’s growth into a
leading CDMA supplier. With industryleading technologies and fast response
to customer needs, ZTE has won wide
recognition among customers and has
taken a prominent position in the global
market.
J: We notice that ZTE’s CDMA
products have not only been widely
used in emerging markets, such as
India and China, but also in high-end
markets, such as Europe and the United
States. What differential advantages do
ZTE’s CDMA products offer in product
solutions and service combinations?
Li Jian: CDMA is one of the product
categories that ZTE has been dedicated
to. Our products are successful for three
major advantages: stable All-IP solution,
GoTa, and product customization
capability.
As I have just said, ZTE launched the
All-IP CDMA2000 products three years
ahead of the industry and provided the
world’s first Ap interface commercial
application and the world’s first IPbased Abis interface solution. With a
thorough understanding of the All-IP
technology, we have also accumulated
much experience in saving transmission
resources and power consumption,
which can help to decrease the
operator’s overall network investment.
GoTa is the world’s first CDMA2000based digital trunking system,
independently developed and launched
by ZTE. It has become a killer application
for CDMA operators. Perfectly blending
professional features and public needs,
GoTa is an effective weapon for operators
in different competitions.
The customization capability shows
ZTE’s strength in quickly responding to
customer needs. I’ll give two examples
to illustrate ZTE’s fast customization
capability. This August we deployed an
EV-DO wireless broadband network to
provide in-flight communications in the
United States; this was the world’s first
Air-to-Ground (ATG) CDMA network
that ZTE customized for Aircell.
Covering a space area of 9.3 million
square kilometers with a radius of 250
kilometers, the network can solve top
technical problems, for example the
Doppler Effect resulted from high-speed
flight. Now this network is providing
EV-DO Rev. A data services for over
1,000 airplanes. ZTE also constructed
the first 450MHz CDMA20001x EV-DO
Rev. A commercial network in Europe;
in merely three months, we customized
wireless base stations operating at Lband for Czech Mobilkom a.s.
J: In recent years, ZTE successfully
swapped the network equipment of all
mainstream CDMA suppliers during the
revamp of CDMA networks in some
areas. Could you please share with us
some information and cases about this?
Li Jian: ZTE has swapped 16,000
CDMA base stations throughout the
world, among which 87%, or 13,000,
were in China. Such successful
swapping cases contribute to ZTE’s
marketing achievements in CDMA.
ZTE has the richest experience
in CDMA network swapping. Its
unique coexistent dual-network precutover solution enables the cutover of
complicated commercial networks in a
smooth, safe manner. In many countries,
including India, Egypt, Jamaica,
Mongolia, Algeria and China, ZTE
swapped base stations of all mainstream
CDMA equipment suppliers.
Especially in China, ZTE successfully
swapped CDMA base stations of all
other CDMA equipment suppliers
in 14 provinces. During our project
implementation this year, despite the
disastrous earthquake centered in
Wenchuan, Sichuan Province, ZTE
overcame various difficulties and
ZTE TECHNOLOGIES November 2008
Interview
completed network swapping in Chengdu
according to the schedule.
After China Telecom takes over the
CDMA network, more larger-scale
network swapping implementations will
be made in order to achieve a reasonable
layout of the CDMA network.
Capitalizing on its rich swapping
experience, ZTE will work together with
China Telecom to expand the CDMA
network coverage in China.
J: China Telecom will acquire CDMA
network from China Unicom. What
significance does this hold for ZTE?
What plan does ZTE have concerning
future cooperation with China Telecom?
Li Jian: After China Telecom takes
over the CDMA network, it will
extend many of its advantages to the
operation of the CDMA network. This
will completely change the pattern
of the CDMA industry and boost the
development of CDMA in China and the
world. As a leader in CDMA equipment
and terminal in China, ZTE will play a
more important role in the development
of China’s CDMA industry. We believe
ZTE is capable enough to make greater
contribution to the fast development of
10 November 2008
ZTE TECHNOLOGIES
China’s CDMA industry.
Concerning the cooperation with
C h i n a Te l e c o m , Z T E h a s m a d e
comprehensive analysis on such aspects
as the status and equipment performance
of the existing CDMA networks,
network planning, network evolution,
network construction procedure, and
service development. Based on such
analysis, we worked out a whole set
of practical and scientific network
construction solutions. China Telecom’s
takeover of the CDMA network will
bring good opportunities to ZTE, and we
are very confident about participating in
China’s CDMA constructions.
J: At present, many traditional
CDMA suppliers have been cutting
investments on CDMA, or even quit the
CDMA market. Why does ZTE stick
to CDMA? Will ZTE shift its business
focus in the future from CDMA2000
evolution solutions to Long Time
Evolution (LTE)?
Li Jian: There is a consensus in
ZTE that the company shall be a firm
supporter of CDMA. The fact that
some other suppliers quit the CDMA
market presents ZTE more opportunities
to expand its market shares. We are
confident in our CDMA capability and
we’ll work with our industry peers to
keep the stable and healthy development
of the CDMA industry.
The CDMA market will keep
growing quickly in India and China.
According to the telecom research
institute under the Ministry of Industry
and Information Technology of China,
China’s CDMA market will keep an
annual growth rate of at least 33 % in
the next several years and 150 million
CDMA subscribers are projected by
2011. The existing customer base of
Reliance and Tata is 40 million and
26.3 million respectively, and the two
Indian operators add 1.5 million new
subscribers each month.
In the future, ZTE will not decrease
investments on the development of
successive CDMA2000 evolution
solutions. ZTE has spent a lot on R&D;
it has been actively participating in the
activities of standardization organizations
and industrial organizations; and it has
positively influenced the evolution
and standardization of wireless
communications technologies throughout
the world.
At present, the standards of various
systems are in constant evolution and
optimization. In the 3G era, CDMA, TDSCDMA and WCDMA all adopt the
CDMA modulation technology; while in
the 4G era, UMB, WiMAX and LTE all
adopt the Orthogonal Frequency Division
Multiplex (OFDM) and Multi-Input and
Multi-Output (MIMO) technologies;
various systems are tending towards
convergence. ZTE’s new generation
soft base station adopts the multi-mode
compatible architecture and can be
smoothly upgraded to UMB/LTE, to
realize a multi-mode base station and
protect operator’s investments. This base
station will be a major product of ZTE
applied to China’s 3G and subsequent 4G
network constructions.

Introduction
According to Informa, global mobile
data revenues will increase 77% from
2007 to 2012 while global mobile data
traffic will grow far faster, increasing
more than 1000% over the same period.
Driven by mobile browsing and video,
this increased network traffic forecast
is leading operators to reinventing
their strategies and this explains why
spectrum refarming and launching of
new and potentially lower-cost systems
are part of them.
Moreover, according to Analysys,

efficiencies over existing 3G
technologies. The cost per byte will
decrease from €0.06 for WCDMA to
€0.03 for HSPA and €0.01 for LTE;
more than 450 million LTE subscribers
are expected from 2010 to 2015
(see Figure 1); related revenues will
reach 15% of market share in HSPA,

ZTE SDR Innovation and Benefits
Based on the future challenges of
network evolutions, ZTE is offering
operators a solution based on its newest
SDR platform featuring powerful
innovation, significant TCO reduction
and future proof RAN solution.
Unified base station platform
(MicroTCA)
ZTE took the strategic decision to
build its new SDR base stations on a
recent technology released late 2006
based on the advanced MC technology
uTCA. It is built on an open, modular
and scalable MicroTCA platform
which offers operators the following
savings:
■ ZTE’s SDR base station required
only 8 modules compared to 12
needed for a traditional Macro
NodeB, thus offering 33% OPEX
Smaller footprint
ZTE’s SDR base station offers a
distributed architecture based on a
BBU and several RRUs, limiting the
equipment room space needed; ZTE
outdoor Macro RRU, ZXWR R8840,
is only 19 liters in volume, 16.5 kg in
weight. ZXSDR BBU B8200 is 2U
height, standard 19 inches in width
and is the smallest BBU with largest
capacity in the industry.
The Macro SDR base stations have
small footprint, offering 25% OPEX
savings compared to traditional base
stations; as a result, no additional site
rentals are proposed.
Future proofness
ZTE’s SDR base station is capable
of meeting the requirements for multibands and mixed networking of GSM/
EDGE/CDMA/WCDMA/HSPA/LTE
and can operate over a wide frequency
range from 850MHz to 2100MHz.
With ZTE’s advanced design, most of
the hardware in SDR base station is
the same and can migrate among 2G,
3G and LTE through software upgrade.
Thanks to the open uTCA platform,
ZTE’s SDR base station can easily
handle the large capacity requirements
the HSPA+ and LTE brought up.
As a result, ZTE’s SDR base station
offers a smooth evolution path to
HSPA+ and LTE: Only RU modules are
needed to upgrade to HSPA+, and only
a new base band board addition and a
software upgrade are needed to evolve
to LTE; over 80% CAPEX savings are
offered compared to a traditional design
requiring heavy hardware changed to
evolve to LTE.
By offering future proof platforms,
ZTE warranties operators that the initial
investments will be preserved, thus
enabling a faster return on investment
with a time-to-market solution.

ZTE SDR Business Case Study
Based on SDR major benefits such
as reduced footprint, limited power
consumption and unified MicroTCA
platform and its unmatched future
proofness, this business case study
compares a mobile network evolution
through GSM-UMTS-LTE based on a
Macro SDR solution with a traditional
Macro NodeB solution.
Assumptions and parameters
In this study, an operator owns a
network with 1100 legacy GSM base
stations and plans to deploy 1100 new
WCDMA base stations in 2 years (400
in 2009 and 700 in 2010). In 2012, all
new 1100 base stations will be upgraded
into LTE while GSM service will be
stopped.
2009-2010
■ 400 new WCDMA base stations
installed in 2009 and 700 in 2010
■ 100% of existing sites, towers,
antennas and feeders are reused
SDR case: swap of legacy GSM base
stations in 2009
Traditional case: co-location of legacy
GSM and new WCDMA base stations;
need of new combiners, power supply
and batteries
Figure 4 Mobile network evolution without ZTE SDR base station

base stations
Swap costs are not taken into
consideration in either of the scenarios.
The smooth evolution path towards
LTE
Figure 5 shows how ZTE’s SDR
base station can smoothly evolve from
a UMTS to a GSM/UMTS dual mode
configuration in a first step, by only
adding a GSM hardware module with a
software upgrade.
In a second step, when GSM service

is stopped, a LTE hardware module is
added while only a software upgrade is
performed to configure a UMTS/LTE
mode.
Business case output
CAPEX savings
After a comparable level of CAPEX
in early deployment, the savings take off
dramatically in year 2012 when LTE is
smoothly introduced with SDR solution.
SDR software upgrade offers over 42%
CAPEX savings to operators compared
to a LTE upgrade on a traditional base
station based on hardware and software
add-ons.
With LTE introduction, NodeB
equipment together with Installation
& Commissioning (I&C) costs can be
decreased by 80%.
OPEX savings
The OPEX savings continue to grow
linearly to reach over 26% savings 9
years after the initial roll-out. Those
savings are met with decreased site
rentals fees, lower power consumption
and limited Operation and Maintenance
(O&M) costs.
TCO
The introduction of SDR base
stations allows operators to reduce
not only CAPEX, such as equipment
costs, network, transport or I&C, but
also OPEX, like site rentals, power
consumptions, leased lines and O&M.
As a result, the TCO savings based on
this study reach over 35% only 4 years
after the initial roll-out.
The study shows also that 80% of the
TCO savings are mostly met in 3 areas:
■ Site rental (43% of TCO savings)
■ Equipment price (NodeB) (26% of
TCO savings)
■ Power consumption (11% of TCO
savings)
Conclusion
With a very strong and innovative
R&D department, ZTE allocates over
10% of its budget to R&D. Today,
nearly 16,000 employees are dedicated
to R&D, among which 4,000 focus on
mobile wireless technologies.
ZTE is a pioneer in the SDR
technology development and was
proud to showcase industry’s first
SDR base station during the Mobile
World Congress in Barcelona in
February 2008. The SDR Base station
is a significant milestone leveraging
ZTE’s wireless mobile experience
based on over 260 million lines
deployed worldwide. It is built on
an innovative open, modular and
scalable MicroTCA platform. With
only a software upgrade, it can be
implemented on multiple technical
standards including GSM, WCDMA/
HSPA, CDMA2000 1X EVDO and
WiMAX. Therefore, operators can
easily expand, manage and maintain
their communications systems while
effectively reducing TCO.
In September 2008, ZTE’s SDR base
station won the InfoVision award in
the New Product Innovation category
during the Broadband World Forum
Europe 2008 in Brussels, Belgium, thus
reinforcing ZTE’s position as a market
leader in network innovation.
This study demonstrates that ZTE’s
SDR base station solution, compared
to a traditional Macro NodeB solution,
offers over 26% OPEX savings 9 years,
42% CAPEX savings only 4 years,
and 35% TCO savings 4 years after the
initial roll-out.

Boosting Operators’ Profitability through
Customization and Quality Service
Han Chengyan
A
ccording to Michael Porter,
the world-renowned
master of competitive
strategy, the three generic
strategies available to enterprises
for gaining competitive advantage
are: cost leadership, differentiation,
and focus. Such strategies have also
become ZTE’s business creed. ZTE
believes that innovation is the essence
of differentiation and customization.
In order to help operators deliver
differentiated products and services,
ZTE needs to constantly explore the
market and customize products and
services.
Customization Capability
Faced with an inferior position in
the 2G market and the challenges from
the leading European and American
vendors in the 3G field, ZTE broke
away from the traditional wireless
networking scheme using macro and
micro base stations and put forward
its innovative idea of “Operation and
Maintenance (O&M) Factory” using
the Base Band Unit and Radio Remote
Unit (BBU+RRU). The BBU+RRU
solution helps operators significantly

Quality Service
decrease capital expenditures (CAPEX)
and operating expenditures (OPEX).
ZTE is the first vendor in the world
to provide the SIM-enabled CDMA
mobile phone. It launched the first
All-IP CDMA2000 system in 2004
and built the world’s first IOS5.0based All-IP CDMA2000 commercial
network in April 2006. To date, ZTE
has commercialized 21,000 All-IP
CDMA2000 base stations, ranking first
in the world.
In 2007, ZTE customized the CDMA
system equipment using the Air-toGround (ATG) spectrum for Aircell,
a US-based provider of airborne
communications. This project made
ZTE the first vendor in the industry
that supports the Advanced Wireless
Service (AWS) spectrum of the United
States. The commercialization of the
Aircell network in 2008 marked the
first successful application of the
CDMA2000 EV-DO air broadband
technology. ZTE has demonstrated
not only its fastness in CDMA product
development but also its strong
customization capability.
Professional Project Management
Being a leader in the CDMA
industry, ZTE has been dedicated to
offering professional services, fast
response, custom-made products,
and one-stop engineering service
solutions. Based on advanced tools
and mature project O&M experience
16
November 2008
ZTE TECHNOLOGIES
in the CDMA field for over 10 years,
ZTE is able to deliver total solutions
involving network planning, project
implementation, and managed services.
To quickly meet customers’ needs,
ZTE has also worked out an overall
hardware deployment and swapping
solution for operators.
■ Set up an efficient project delivery
team headed by the Project Manager
(PM) with Project Management
Professional (PMP) certification;
organize and establish support
teams including the network
swapping requirement analysis
team, project implementation team,
and quality assurance team;
■ Stock up in advance and guarantee
timely arrival of equipment to meet
the operator’s requirement for fast
network swapping; swap Network
Elements (NEs) in different sites
simultaneously to ensure the project
is completed on time;
■ Adopt a safe seamless network
swapping scheme combined with
the redirected cutover mode and the
field-proven overlapping coupler
solution to ensure the network
elements are smoothly swapped at
a time;
■ I m p r o v e u s e r e x p e r i e n c e b y

Key account service has been seen
as the litmus test of an operator’s
service capability. A well-developed
key account system can help the
operator significantly improve service
quality delivered to larger clients.
For a three-dimensional network,
the drive test data or fixed-location test
data show only the status of the tested
nodes, while the statistical data from
the network management system show
the status of the whole network instead
of individual nodes. It is necessary
to have a record that shows the realtime status of both individual users and
the whole network. Therefore, a Call
Detail Trace (CDT) system has been
introduced to meet this requirement.
The CDT system records the key data
collection and call processes. Network
optimization engineers can check the
CDT data to analyze each call failure or
get overall information of the network.
ZTE has successfully deployed the
CDT system for China Unicom’s Hainan
Branch. This system provides such
functions as fault detection, performance
monitoring, and network guarantee. It
can implement special management
on resources and services related to
large clients, make regular reports on
their network performance and service
experience, and thus guarantee the
delivery of quality service to them. By
using the advanced network optimization
technologies and highly flexible
application software, the CDT system
significantly improves transparency
in network O&M and transforms the
traditional KPI-based network O&M
into user experience based O&M, thus
guaranteeing quality service for large
clients while bringing considerable
economic benefits to operators.
Exploring a Safe Broadband
Blue Ocean for Carriers
Li Tao
W
ith the expansion of
Internet-based services,
users are facing the
increase of serious
security problems. This poses a pressing
need for network security products
and therefore drives rapid growth of
the network security market. In 2007,
the overall sales revenue of network
security products in China, including
firewall, VPN, IDS/IPS and the related
service but excluding software products
and service, reached RMB 6.375 billion,
an increase of 18.8% over the previous
year. As predicted by CCID Consulting,
the scale of network security product
market in China will keep growing,
with revenue of over RMB7.5 billion
in 2008. Also according to the CCW
Research, the sales for China’s network
security market are expected to reach
RMB8.1 billion in 2009.
The huge need for network security
products presents new opportunities for
fixed-line network carriers. They can
lead the development of the network
security industry by delivering beyond
basic network services that can solve
network security problems, thus
transforming into integrated information
service providers.
Establishing a Secure Operation
Platform
As security threats to Internet
are changing and have a complex
nature, more and more enterprises and
organizations expect their IT systems to
run smoothly around the clock.
The major concern of telecom
carriers is how to solve broadband
network security problems, which is also
the determinant of winning more market
share in broadband business. They can
launch featured safe broadband services
to compete with their rivals. With the
cost-efficient small-sized security
products, they can deliver professional
security service to online subscribers,
helping boost customer loyalty and
increase the ARPU.
Telecom carriers can promote
varieties of new data services, such as
broadband e-commerce and broadband
experience, only when subscribers
believe that data over broadband are
secure enough not to be wiretapped.
Leveraging unique advantages in
capital, network resources, technologies
in the fields of transmission, data
communications and surveillance, and
long-term stable service provisioning,
telecom carriers can take the lead in
the network security field, producing
a revolutionary influence upon
the traditional business mode and
development of the entire network
security industry.
Therefore, ZTE unveils its
manageable, operational and scalable
broadband security services based on
a secure operation platform, strongly
protecting the successful transformation
of telecom carriers.
Core Value of Secure Operation
The Unified Threat Management
(UTM) gateway tailored by ZTE for
telecom carriers provides various
security functions based on a centrally
managed platform. It is integrated with
many security services necessary for
enterprises, such as anti-virus, firewall,
and intrusion detection, which can be
flexibly and easily managed. ZTE’s
UTM secure gateway service features
centralized management, simple
deployment, easy maintenance, and
wide coverage.
Centralized management
The UMT Center can manage
security policies, service functions and

gateways, helping telecom carriers
guarantee high value-added security
consulting service.
Simple deployment
The two commonly used deployment
solutions (router mode and transparent
mode) basically cover the majority of
application scenarios. The multiple
pre-defined security policy packages
help engineers quickly get started with
security policies.
Easy maintenance
The UMT Center allows telecom
carriers to perform service change,
log collection and statistics analysis
on a remote terminal, greatly reducing
maintenance work.
Wide coverage
The UMT Center provides a wide
array of security services including
firewall, anti-virus, VPN, intrusion
prevention, web information filter
and spam filter to address the network
security needs of enterprises at low cost.
With a secure operation platform,
telecom carriers can help high-end users
rapidly deploy manageable services
such as VPN, anti-virus gateway and
intrusion prevention, and charge proper
fees for these services. Through the
market segmentation and differentiated
services, they can shift their focus from
the broadband access market to multiple
services provision and thus transform
into multi-service providers. Moreover,
they can provide the managed service
for small- and medium-sized enterprises
that are not well capitalized. For
example, the leased UTM secure
gateway service allows these enterprises
to enjoy professional SOC security
consulting service at low cost. Once a
telecom carrier sets up a unified security
platform, the small- and medium-sized
enterprises can select complete or partial
security services as they like. They can
18
November 2008

flexibly add or change security functions
on the platform, which makes the work
of security management personnel easy
while reducing operation costs.
Application Scenarios
ZTE’s UTM secure gateway (see
Figure 1) provides a complete range of
security functions that can be flexibly
configured, meeting the information
security requirements of different
enterprises and organizations.
F o r m e d i u m - a n d l a rg e - s i z e d
enterprises, ZTE’s UTM secure gateway
prevents hackers and viruses by the
firewall and Intrusion Prevention System
(IPS) and greatly cuts spam messages
using the filter.
For small- and medium-sized
enterprises, ZTE’s UTM secure gateway
uses the firewall to restrict and record
Internet surfing by employees, and
uses the control function of the P2P/
IM instant communication software
to control and record the employees’
actions that affect their working
efficiency such as BT download and
MSN/QQ chat. Furthermore, the UTM
secure gateway can use traffic shaping
to guarantee network bandwidth for core
services of the enterprises.
Carrier
Secure Operation Platform
For school education systems, ZTE’s
UTM secure gateway uses the anti-virus
protection and web information filter
to effectively protect against virus and
malicious information attacks.
For chain enterprises, ZTE’s UTM
secure gateway sets up secure channels
in the public network through VPN for
data transmission and uses the firewall
and anti-virus software to guarantee the
security of intranets.
For the governments and financial
institutions where both extranets
and intranets are easily attacked and
infected, ZTE’s UTM secure gateway
protects external web servers through
the firewall and IPS and protects
intranets via the anti-virus tools.
With many years of construction
practice in the network security field,
ZTE put forward the innovative concept
of building a secure broadband valueadded service platform, opening up new
opportunities for carriers to promote
broadband services. The UTM secure
gateway provides security protection for
broadband networks while driving the
growth of broadband-based value added
services, helping carriers sail bravely
against waves in the broadband blue
ocean.

TD-HSPA MX : The Key to Breaking
the High-Throughput Bottleneck
TM
Jiang Chun, Wen Gang
I
t is predicted that China’s mobile
communications market will
attract 300 million new subscribers
in the coming three years,
continuing to maintain a high growth
rate. As more users are moving from
voice to data and video activities such
as mobile podcast and video download,
the throughput of mobile systems may
become a bottleneck in the expansion of
data services. How to lower the cost per
bit of data while increasing the network
throughput has become a challenge for
mobile carriers.
To solve this bottleneck problem,
ZTE launches its patented Time
Division-High Speed Packet Access
MX (TD-HSPA MXTM) technology. It
can help carriers exponentially increase
the cell throughput through software
upgrade without additional investment
in hardware, thus guaranteeing the
provision of quality data services.
Technical Features
The TD-HSPA technology offers
higher data throughput than other 2G/3G
wireless technologies using the same
bandwidth, as shown in Figure 1. As the
number of data subscribers increases,
the capacity of the TD-HSPA system
would be a bottleneck for further
expansion of data services. Generally, 6
of the 9 current available TD frequencies
(15MHz bandwidth) are used outdoors,
and the other 3 frequencies are used
indoors. Since 70% of wireless data
services occur indoors, the indoor
capacity constraint is more prominent.
To solve this problem, ZTE rolls out its
proprietary HSPA MXTM technology to
considerably increase data throughput
of the TD-HSPA system without
adding carrier resources, modifying
users’ terminals, or changing network
planning. It is a cost-effective solution
to the frequency constraint problem in
dense urban areas and hotspots.
ZTE’s HSPA MXTM technology has
the following features:
High throughput
The HSPA MXTM technology can be
used both indoors and outdoors. It helps
to increase the system throughput by 1.8
to 2 times when deployed indoors and
by 1.3 to 1.5 times when used outdoors.
Self-adaptiveness
The system can determine whether
to use the HSPA MX TM technology
according to the specific application
environment. For example, when there
are many active subscribers in a cell,
the HSPA MXTM function is activated
to guarantee the cell throughput; when
there are few active subscribers, the

Software upgrade
The HSPA MX TM technology is
implemented on by software upgrade
without any alternation to terminals and
network planning.
Application Principles
The principles of applying the HSPA
MXTM technology indoors and outdoors
are different. For the outdoor application,
ZTE’s HSPA MXTM algorithm and the
Space Division Multiple Access (SDMA)
principle combined with the TD smart
antenna technology are used. In the
case of outdoor macro cell coverage, as
subscribers are separated in space using
the beam forming function of the smart
antenna, ZTE’s HSPA MXTM algorithm
can be used to enable reuse of radio
resources for subscribers, i.e., to make a
full reuse of frequencies, timeslots and
code channels for different subscribers,
as shown in Figure 2. HSPA MXTM helps
to increase the data throughput 1.4 times
higher than that of the standard HSPA
system.
For the indoor coverage, ZTE’s
HSPA MXTM algorithm and the SDMA
principle combined with the TD multipath technology are used. As subscribers
are separated by the indoor floors and
walls, ZTE’s HSPA MX TM algorithm
and multi-channel indoor coverage
technology can be used to enable reuse
of radio resources for subscribers (see
Figure 3). The HSPA MXTM technology
is more suitable for indoor application,
ZTE TECHNOLOGIES
November 2008
19
Tech Feature
because the system throughput can be
almost doubled. Therefore, the adoption
of the HSPA MX TM technology can
better address the indoor throughput
requirements of enterprise and home
mobile data users.
The cell throughput can be increased
in several ways, such as adding new
devices and introducing new technologies
like 64 Quadrature Amplitude Modulation
(64QAM) and Multiple-Input MultipleOutput (MIMO). The upgrade costs and
throughput gain vary with the method
used. Table 1 shows that ZTE’s HSPA
MXTM has great advantages over other
methods in terms of upgrade costs and
throughput gain.
Case Study
We’ll take the deployment of the
HSPA MX TM technology inside a
building in Beijing as an example. The
building is 60 meters high with 16 floors
above ground and 3 floors underground.
The signal isolation between the floors
in this high-rise concrete building is
about 20dB. The building is divided into
two cells: Cell 1 and Cell 2. To cover the
whole building, 3 R01s are deployed in
Cell 1 and 4 R01s are deployed in Cell 2
(see Figure 4). The site type is O1 and 1
HSDPA timeslot is configured.

The test is conducted in two parts:
before HSPA MX TM is deployed, it
is difficult to handle voice and data
traffic simultaneously, because the
configuration of 1 HSPA timeslot
can only provide a cell throughput
of 560kbps and 12-channel voice
subscribers; after HSPA MX TM is
deployed, both voice and data traffic
can be handled, with the data capacity
reaching 1008kbps while voice capacity
remaining unchanged. The test results
prove that HSPA MX TM technology
helps to increase the system throughput
by 80% without any alteration to
terminals and network planning.
Conclusion
To satisfy the need of fast-growing
3G data services, ZTE launches the
innovative HSPA MX TM technology
based on ZTE’s great R&D strength and
proactive product planning. Taking into
full consideration the service demands,
spectrum efficiency and feasibility, HSPA
MXTM will certainly help carriers build
cost-effective and advanced networks
and will make a great contribution to the
global information construction.

Overview
elecommunications networks are a combination of multiple
service networks (voice, data and video) and service supporting
networks (fixed, wireless, transmission and SS7 signaling
networks). Network resources are closely related and dependent
to each other to provide services corresponding to each resource included
in the network. There are heterogeneous deployments in these service
networks, partially or completely utilized by multiple vendors. Each
vendor has designed the Element Management System (EMS) for his own
specialized network equipment deployed in the market, so different services
and resources have different Operation Management Systems (OMSs).
The legacy network management architecture has heterogeneous EMS
for each independent network element. These distributed EMSs have the
following disadvantages:
Lack of interoperability
With the lack of interoperability between EMSs, the network resources
cannot be assigned and managed uniformly. This non-uniform network

and presentation is also heterogeneous,
and as a result leads to the inconsistency
in measuring overall network statistics.
High CAPEX and OPEX
The legacy NMS has multiple
distributed EMSs to manipulate and
manage services. This distribution
of EMSs results in the duplication
of resources and incurs high Capital
Expenditures (CAPEX) and Operating
Expenditures (OPEX).
Therefore, it is concluded based on
the above analysis that a new network
management system is in urgent need to
solve the problems of poor maintenance
and high operation costs.
ZTE's Integrated Network Management
Solution
There have been continuous
research and improvement for the
network management system for the
service networks. After many years of
research and practice, ZTE rolled out
its integrated network management
solution, NetNumenTM UNMS, which
is based on the TMN model to fulfill
present industry demands and support

Benefits
The integrated network management
solution provides operators with flexible
and cost effective systems to monitor
and control heterogeneous networks. It
has the following benefits:
■ Unified management of multivendor devices
The major driving and leading
benefit of integrated management is the
unified management of heterogeneous
networks. This integration provides a
single point of login and monitoring
of all types of network elements for an
underlying network. Operators can get
the information about the relationship
between multiple EMSs and perform
the correlated operations. The unified
management leads to consistence of
daily operations of telecom networks.
■ High fault management efficiency
NetNumenTM UNMS has a unified
alarm management capability, so it is
possible to perform the correlation of
alarm related to the whole network
and get the statistics of the whole
network. It is easy to obtain and
resolve the network performance and
failure related issues based on the daily
statistics. Moreover, root failures that
may affect the whole network can be
traced and rectified in time. Therefore,
fault management efficiency of the
whole network management system is
greatly enhanced.
■ Strong extensibility
NetNumen TM UNMS offers strong
extensibility because of its unified
and standard interfaces connectivity.
Whenever a network is expanded and a
new EMS is added, it is only necessary
to develop an interface with the UNMS
and make small changes to the UNMS
functions. The new EMS then could
be connected smoothly to the existing
UNMS.

Inventory Management
Non-uniform user interfaces
The legacy Network Management
System (NMS) has no standard
interfaces. The non-uniform user
interface increases the work overhead
due to multiple monitoring systems and
users have to login to multiple EMSs
respectively to monitor and control
the statistics data and other related
operations.

FMS), Performance Management
S u b s y s t e m ( N e t N u m e n TM P M S ) ,
Security Management (NetNumen TM
SM), NetNumenTM Portal, NetNumenTM

and PM Adapter, as shown in Figure 1.
■ NetNumen TM FMS: It implements
unified fault management of the
whole network through the FM
adapters. The FMS module handles
the alarm data collected by the
corresponding adapter from all the
subsequent EMS networks and
then sends the result to the FMS
client. Therefore the simultaneous
login operations to multiple
EMSs are transformed into single
login operation with the unified
architecture.
■ NetNumenTM PMS: It is responsible
for unified performance management
of the whole network through the
PM adapters. The PMS module
processes the information collected
through the corresponding adapter
from all the subsequent EMS
networks and then sends the result
to the PMS client. Moreover, it has a
communication interface with FMS
to send the threshold-crossing alarms

With the help of these GWs, FMS
exchanges resource data with the
Inventory Management (IM) system
and dispatches trouble tickets to the
Trouble Ticket System (TTS) for
fault recovery. Similarly, PMS sends
performance analysis data to the
Service Quality Management (SQM)
system through the gateway for
relevant analysis.
NetNumenTM Reporter: It is a report
management tool that receives alarm
data from FMS and performance
data from PMS, and that generates
custom-made fault statistics reports,
performance statistics reports and
performance trend reports.
Independent deployment of FMS
and PMS
NetNumenTM FMS and NetNumenTM
PMS have flexible architecture to be
deployed separately as two standalone
systems depending upon the use

Figure 3 NetNumenTM PMS System Model
FMS has a layered architecture
consisting of data presentation, data
processing and data collection layers,
as shown in Figure 2. The adapter at the
data collection layer collects alarm data
from the lower EMSs. The FMS server
at the data processing layer performs
the necessary processing such as data
filtration, compression, correlation
analysis, and root cause determination.
Therefore, the maintenance staff
only needs to focus on the root
problems, which helps to reduce their
maintenance work.
FMS decreases the quantity of
maintenance consoles by enabling
the unified alarm supervision and
processing for devices incorporated in
all specialized networks from multiple
vendors. Monitoring of the entire
network is supported through a single
interface. Network fault determination
and processing is speeded up and
users can recover the fault in time. The
passive maintenance technique triggered
by customer complaints is thus changed
to a preventive method and the impact
of service failure is improved greatly.
■ NetNumenTM PMS
PMS also has unified but layered
architecture consisting of data
presentation, data processing and data
collection layers, as shown in Figure
the lower EMSs. The PMS server at
the data processing layer analyzes the
performance data, provides performance
analysis reports and performance trend
reports, and also predicts performance
bottlenecks. With the help of the
performance reports, users can make a
horizontal comparisons, figure out the
potential flaws and faults in different
regions and finally provide guidance
for routine maintenance, network
optimization and capacity expansion.
When a performance threshold is
reached, PMS can trigger thresholdcrossing alarms and send them to FMS,
timely notifying the users that remedial
measures should be taken.
Conclusion
Z T E ’s N e t N u m e n T M U N M S i s
an integrated network management
solution developed after in-depth
analysis, research and examination of
present telecom network operation and
maintenance difficulties. Therefore, it is
a powerful weapon for telecom carriers
to increase network operation efficiency,
lower maintenance costs, increase
subscriber satisfaction and enhance
market competitiveness, and meanwhile
it helps the carriers open the door to
multi-vendor device management.

ore and more broadband
network nodes are getting
closer to the customer
premises in order to increase
bandwidth. The shorter the copper wire loop
the higher number of nodes will be required.
The current Fiber-to-the-Building (FTTB)
architectures need an average of millions of
nodes. No one can afford such a huge number
of houses or rooms to store equipment in. The
only way out is outdoor cabinet that is small
enough to be hanged on the wall or pole.
Indoor office
Big office needed
High cost of land
Outdoor cabinet
Small space needed
Low cost of land
Wall/pole mounted cabinet
Smaller space needed
Zero cost of land
Table 1 The development tendency of cabinets
Previously, most of the access nodes
were indoor nodes, which needed big
offices to house them. Now we install
the access nodes in outdoor cabinets so
that only a small space is needed, and
the cost of land will be lowered. If we
continue to move the nodes closer to
users, wall or pole mounted cabinet can
be used, and there will be no cost for
space and land. As land is becoming an
increasingly precious resource, these
smaller outdoor cabinets will bring huge
cost savings. Meanwhile, more land
will be used for plantation development,
which is beneficial to our environment.
Planning Outdoor Cabinet Solution
In order to simulate the indoor
environment, the outdoor cabinet design
takes into account such factors as safety,
temperature control, long-distance
monitoring, and power-cut protection.
Cabinet based on such design will
conform to the telecommunication
standard. Considering the requirements
of different environments, ZTE provides
a series of outdoor equipment with
different capacities.
An outdoor solution is planned
mainly according to the volumequantity model of FTTB/C nodes. The
volume of most of the nodes is less
than 96 ports; that of some nodes is
between 96 ports and 192 ports; and
some big FTTC nodes need several
hundreds but usually less than 896
ports. Nodes with more than 896 ports
will be placed in room bases.
Therefore, two kinds of outdoor
cabinets were planned to house
mini DSLAM or Multiple Dwelling
Units (MDUs). ZTE defined them as
the OUT80 and OUT50 series. The
OUT80 has a maximum capacity of 96
ports while the OUT50 can support up
to 192 ports. The big cabinet, OUT40,
was also developed to support up to
896 ports.
When the OUT80 works together
with ZXDSL 9806H, a mini DSLAM
from ZTE, it is very easy to put this
compact outdoor equipment on the
wall of a corridor, so that people
passing by will not be disturbed. The
OUT80 can also be hung on a pole
close to a building, or hung under the
eaves.
As we know, fan is widely used
in outdoor solution. Adjustable fan
technology brings great energy savings
to the outdoor nodes. The speed of fan
can be automatically adjusted according
to the environment temperatures,
decreasing the energy consumption.
Savings from Outdoor Cabinet
Solution
The cost savings from the green
outdoor broadband solution can be
looked upon from the following aspects:
equipment rooms, materials and power
of DSLAM and accessory equipment.
We will take the X project as an
example to illustrate the cost savings.
The X project needs 5,000 FTTB nodes,
and on average each node has 48 ports.
Assuming that the average area of these
nodes is 15 square meters, a total indoor
area of about 75,000 square meters is
needed. If the price is 1,000 USD per
square meter, the equipment rooms
will cost 75 million USD. If the rental
price is 100 USD per month, renting
the rooms for a year will cost 6 million
USD. On the contrary, millions of USD
can be saved if the operator adopts the
outdoor solution.
Furthermore, the outdoor cabinet
solution minimizes the total external
dimensions. The small equipment
will save lots of materials, including
materials of rack, power supply unit and
other accessory components, and will
have less power consumption compared
with the scenario where big equipment
is installed in indoor rooms.

Case Study
ZTE, TELEVÕRK Team up to Build Wireless
Broadband Network in Estonia
Jiang Yun
T
ELEVÕRK, a wholly
owed subsidiary of an
Estonian state-owned
e n e r g y c o m p a n y, r u n s
one of Estonia’s largest backbone
communication networks. At the
end of 2006, TELEVÕRK was
awarded a 450M license in Estonia,
and constructed a high-speed data
service network that covers the entire
country. Currently, TELEVÕRK has
the highest growth rate of wireless
broadband subscribers in Estonia.
Individualized Solution
The Estonia telecommunications
infrastructure is the most advanced
in Eastern Europe. The country
has advanced fixed network
infrastructure and a wireless voice
penetration rate of over 100%.
E-government and E-commerce have
become common place in Estonia,
e.g. more than half of the drivers pay
for parking via their mobile phones.
There are already quite a few
mobile operators in Estonia. The
wireless voice sector has almost
reached saturation, while wireless

(ARPU) than wireless voice service,
and is the greatest profit growth
opportunity for emerging operators.
Based on the actual conditions of
TELEVÕRK, ZTE suggested that the
operator give up voice service, focus
on data service, and concentrate
its investment on building an EVDO data network, so as to enhance
network quality and attract more
wireless data subscribers.
The coverage of wireless data
service needs to be large, but in hot
spot cities there is a concentration
of subscribers and a large volume of
data. So it is critical for the network
to provide flexible configuration and
highly dense coverage. ZTE’s AllIP EV-DO equipment, which features
high integration, large capacity,
flexible networking and low power
consumption, met TELEVÕRK’s
requirements. After strict tests, ZTE
was chosen by TELEVÕRK to build
up a state-of-the-art EV-DO data
network in Estonia.
Quick Subscriber Growth
TELEVÕRK began allocating
numbers on June 20, 2007. During
the first 10 days, the operator had
allocated 3000 numbers, and had
developed 9244 subscribers in 100
days. The number of subscribers
increased at a rapid rate (Figure 1).
As for December 21, 2007, the

Advanced network technologies:
The network uses 3G technology
to enable high speed, good
coverage and mobility.
■ Successful commercial mode:
The tariff packages are simple
and clear, and the prices of ZTE’s
terminals are reasonable.
■
IP-based Abis
Figure 1 The increase of subscribers
during the first 100 days
number of network subscribers
had reached 12439, meeting the
operator’s goal of developing 12000
subscribers before 2008. In a country
with a population of 1.34 million,
it was beyond the expectation
of TELEVÕRK that network
subscribers could have increased at
such a high speed. TELEVÕRK’s
good growth momentum can be
attributed to the following reasons:
■ Clear market position: Avoiding
competition in the mature voice
market, the operator focuses on
developing high-speed wireless
Estonia, where Skype was founded,
leads Europe in basic IP network
development. TELEVÕRK has limited
E1 resources, but its IP backbone
network has complete coverage and
high quality and is capable of covering
sites without E1 transmission resources.
ZTE’s IP-based Abis solution makes
full use of TELEVÕRK’ existing
transport resources, saving network
investment and shortens network
construction period.
In the phase I network, 54 out of
95 nationwide base stations use IPbased Abis solution. It is the first
time that IP-based Abis has been
put into commercial use on a large
scale. IP-based Abis provides another
means for transport between BTS
and BSC.

ZTE’s Handset Strategy: A Can of Worms

T
he clear leader in TDSCDMA devices in its home
market, ZTE’s ambition
abroad is to be every
operator‘s best friend, leveraging its
huge technical resources and scale
to drive high-end functionality right
across the handset spectrum. Having
cracked the market for operator ownbranded handsets at the lower end of
the range, ZTE’s impact on the market
for high-end, open-platform devices
will be fascinating to watch.
ZTE’s Status Quo―Whatever You
Want, Whatever You Like
Ovum recently spoke with ZTE’s
handset management about the Chinese
t e l e c o m s e q u i p m e n t p r o v i d e r ’s
burgeoning cellular devices business,
both in its home market and elsewhere.
ZTE’s growth in the handset markets
has been rapid. From 15 million units
shipped in calendar-year 2006, the
company is on course to ship 50 million
in 2008―over 100 million since it
started the business in 1998―making
it the clear global number six handset
provider by volume. That’s no mean
feat for a Chinese handset manufacturer
which was virtually unknown outside
its home market two years ago.
More than 80% of these are cobranded with and customized for its
operator partners, including major
scalps such as Vodafone, Telstra and
Reliance, as well as China Mobile,
China Telecom and China Unicom at
home. ZTE perceives its flexibility
in meeting operator customization
requirements on a huge scale as a key
to this success.
In its home market, ZTE is a
frontrunner in 3G devices and a clear
leader in TD-SCDMA, owning more
than 30% of the total market. For the
most part, though, ZTE’s impact on
the handset market outside China has
tended to focus on low-end and midrange handsets, where it is doing very
good business in both emerging and
mature markets.
To date, its overseas 3G activities
have focused on the buoyant market
for USB modems for laptop PCs. ZTE
is very proud of this business, which
it has said is now on track to ship over
6 million such devices by the end of
2008 and which it expects to expand
to around 20 million by the end of
2010, despite the rapid emergence of
embedded 3G modems.
Opening a New Window on Microsoft
Handsets
But being a volume supplier of
low-end and mid-range handsets was
never going to be enough for ZTE.
With operator and public interest
increasingly directed towards high-end,
Internet-capable devices, it was only
a matter of time until ZTE looked to
boost its profile through targeting that
market.
That breakthrough now looks
to have happened. ZTE will begin
shipping Windows-Mobile-powered
devices with Vodafone next year and
there are signs of other such deals.
Indications are that these will seriously
undercut similar devices from other
manufacturers, as a result of ZTE’s
scale.
HTC is ZTE’s main competitor
in this segment, although it cannot
really be considered a rival in
overall scale. While other OEMs
have adopted Windows Mobile, they
have either lacked the scale to truly
build momentum for the platform,
even if adopted by operators (e.g.
E-ten, Inventec), or have lacked the
commitment to drive the platform deep
into their portfolios (e.g. Samsung,
Motorola). ZTE could potentially do
both.
Whether it will or not remains to be
seen. ZTE’s desire to please operators
is something of a double-edged sword
in terms of the depth of commitment it
can bring to Windows Mobile.
Is Linux a Diversion Even If
Operators Demand It?
Instead of committing fully to
Microsoft technology for its openplatform devices, ZTE confirmed that
it also plans to support Linux to meet
operator demand for such handsets.
Which variant or variants ZTE plans
to support is as yet unclear. What is
clear, however, is that ZTE is putting
considerable resources behind its Linux
project.
The same cannot be said for
Symbian. While ZTE said it was
interested in Symbian―especially
in terms of its competitive cost to
manufacturers relative to Windows
Mobile or Linux―it has not yet put
any serious R&D effort behind the OS,
citing Nokia’s near monopoly of the
Symbian handset market (outside of
Japan, at least).
Interestingly, Symbian’s trajectory
towards open source does not by itself
appear to be enough to cajole ZTE to
alter its stance. We’re guessing that
operator demand could change this,
although such a project would take at
least two years to bear fruit.
