Introducing
Phonelines Home
Networking
The Home Networking Challenge
• Creating a technology that can deliver high-speed networking in
the home is a challenging task
– Commercial networks are designed from the ground up to
minimize noise & interference
• High-speed, corporate networks typically use fiber optic,
twisted pair, or coaxial cables that are dedicated for a
single use
• Manufacturers are free to design commercial network
products for reliable, noise-free environments
– Most homes do not have dedicated high-speed network wiring
• Cost & labor required to install such wiring is high for
homeowners & small business owners to fund
Home Networking
Requirements
• Consumers prefer home networks that
– Use the existing wiring infrastructure
– Are easy to install
– Leverage existing standards
– Work together with common OS and software platforms
• Home networks must implement a QoS mechanism
– Quality of service provides low latency for telephony, and
streaming audio & video applications
• Home networks should be very robust and provide connectivity to
essentially every home
Home Networking
Requirements
• Home networks should support data rates in excess of 10Base-T
Ethernet
– Provide scalability to 100Mbps
– Compatible with earlier generations and be future safe
• Employ scalable & extensible designs to prevent “fork-lift”
replacements when upgrading networks in the future
• They must provide reasonable privacy at the physical layer
• Home networks must be implementable at low cost with a wide
variety of products
Phoneline Home Networking
• Networking information appliances in the homes using existing
phone lines infrastructure
– Using existing phone lines and regular phone jacks to connect
consumer devices such as PCs, digital TVs, DVD/MP3/CD
players to each other and to the Internet
– Exchange of data, voice and video between appliances using
phone lines
Are Phonelines A Natural
Solution for Home Networking?
• Yes
– Phonelines meet most of the HN requirements
• Uses pre-existing home telephone wiring to transmit data
– Phonelines HN is promoted aggressively by the home
phoneline networking alliance (HomePNA)
• 115+ members
• Endorsed by top OEMs for different industries
– PC manufacturers sell phoneline home networks as
add-on with PCs
– Technology can be easily integrated into silicon
Are Phonelines A Natural
Solution for Home Networking?
• But
– Home phonelines were not designed for high speed data
transmission between multiple appliances
– Phone jacks are not ubiquitous in every home worldwide
• Technology could lose momentum when it attempts to
move beyond the US
– While US households tend to have multiple phone
jacks, other countries are often limited to one or two
phone jacks per home
– Homes with multiple phone lines are limited to confining the
network to one phoneline
Issues
• Random wiring topologies & signal attenuation
– Telephone wiring structure within each home is different
– Home phoneline wiring system is a random “tree” topology
• It is not a hub structure similar to business networks
• Simply plugging in the phone or disconnecting the fax changes
the tree
• This topology can cause signal attenuation
– Open plugs & unterminated devices can cause impedance
mismatches, signal echoes & lead to multi-path signals
• Signal noise
– Appliances, heaters, air conditioners, consumer appliances &
telephones can introduce signal noise onto the phone wires
Issues
• Changing transmission line characteristics
– Network must be able to function reliably despite changes
resulting from someone picking up the phone or receiving a fax,
or an answering machine recording a message
• Coexistence with other phone line equipment & compliance with
FCC regulation
– Must use signals with low power levels
• Further complicates the task of establishing adequate
signal-to-noise ratio
– Must work without interrupting existing phone services
• Performance
– High reliability at speeds of at least 1Mbps
Phoneline Market Outlook
• Huge short-term and long-term growth outlook for phoneline home
networking*
– In 2000, phoneline-based home networks will account for 34%
of the installed base
– By 2004, proportion will grow to 72% of total HN market’s
installed base
• Widespread PC OEM support & multiple aftermarket
solutions
• HomePNA is the de facto phoneline networking standard
• Widespread educational marketing campaign will gain
marketing acceptance for the technology

Phoneline Home
Networking
Technology
Technology Leveraging Standards
• Only protocols that have been extensively tested for many years in
real use are ready for large scale deployment
• HPNA has chosen IEEE-802.3 layer 2 networking
– Uses 802.3 framing & Ethernet CSMA/CD MAC behavior
• Guarantees
– Interoperability between equipment from multiple
manufacturers
– Support for networking standards, particularly IP suite
Technology - QoS Support
• HN applications such as transport of digital audio, video and voice
(IP telephony) drive the need for QoS
– Latency in voice connection must be controlled below 10 to 20
ms for voice quality to be maintained
• HPNA 2.0 has an aggregate throughput of 10Mbps
– Adequate for many application scenerios
– Burst loads presented by TCP transfers between PCs without
QoS makes the network unable to meet the latency &
guaranteed bandwidth service requirements
• HPNA 2.0 MAC layer introduces 8 priority levels & an improved
collision resolution technique
Technology - Robustness
• Ad hoc home wiring topology results in
– Reflections & frequency-dependent channel transfer functions
– Uncharacterized & highly variable wire transmission
parameters especially at higher frequencies
– Telephone instruments on the same wiring that present a wide
range of frequency-dependent impedance
– POTS signaling & ringing which produces significant transients
– Impulse noise coupled from AC power wiring that is seen on
many phonelines
– RF ingress & egress particularly in the amateur RF bands
• Phonelines are robust supporting up to 500 feet of phone wire
between devices connected to RJ-11 jacks
Technology - Performance
• Rating of up to 10Mbps
• HPNA 2.0 with a self-describing frame format with PHYlevel signals directly control equalizer training &
demodulation
Technology - PHY Layer Privacy
• Powerline & wireless technologies allow users to share the same
physical medium
– Encryption at the link level helps attain a degree of privacy
equivalent to the phone line
– Requires some user user key configuration thus defeating the
plug-and-play objective
• Privacy in phone wires is not a substitute for true cryptographic
security
Technology Future Safeness & Cost
• Future safeness
– Once installed home networks remain in place for several
years
– Home networks interfaces become embedded in appliances
and impossible to replace
– Good HN technologies build future generation interoperability
into current generations
• Cost
– Home networks should be at consumer prices with few,
additional requirements of external components
Phoneline HN Technology
• Based on HomePNA 2.0 - the de facto industry standard
• Easy to use
– User must install the software, set up the network through both
the software settings & physically connect to the phone jack
• Security is excellent
– Each home has a unique phone circuit (phone number) from
the phone company’s CO
Critical Aspects of the
Phoneline HN Technology
• Foundation is based on Ethernet technology
– Packet based architecture
• Spectral compatibility
– Allows the network to coexist with other telephone services
and emerging broadband Internet access
• High performance encoding scheme
Leveraging Ethernet
Technology
• Home phoneline networking technology uses standard Ethernet
technology
– It is adapted to overcome challenges of the home phoneline
environment
– Enables phoneline HN to leverage the tremendous amount of
Ethernet-compatible software that exists today while meeting
the needs of the home environment
• IEEE 802.3 compliant MAC
• CSMA/CD as access method for sharing the baseband signal on
the home network bus
– Carrier Sense Multiple Access with Collision Detect
CSMA/CD
• When a station has data to send, it first listens to the channel to
see if any other station is transmitting
• If the channel is busy, the station waits until it becomes idle
• Collisions occur when 2 stations listen for traffic, hear none, and
then transmit simultaneously
– This causes both transmissions to be damaged
– Stations must retransmit at some later time
• Back-off algorithm determines when the colliding stations should
retransmit
Leveraging Ethernet
Technology
Source: Intel Corporation
The home phoneline networking data frame is based on
Ethernet standards with a specialized header
Leveraging Ethernet Technology
• Data originating from applications within the PC
– Formed into standard 802.3 Ethernet data frames
– Passed to the phoneline PHY
• PHY circuitry strips off the first 8 octets of the Ethernet
frame (preamble & delimiter fields) and replaces it with a
PHY header designed specifically for phoneline networking
• Receiver - Reverse is executed
– PHY is used to establish the validity of the frame
– PHY header is stripped off & replaced by a IEEE 802.3
compatible preamble & delimiter field
– At this point the PHY can pass the frame to a standard
Ethernet controller for passage to upper layer applications
Peaceful Co-existence:
Spectral Compatibility
• Ensure compatibility with other communication services within the
home
– Home phoneline networking must work with voice & emerging
UADSL (universal asynchronous DSL) data services
• Home phoneline networking uses filtering technology - Frequency
Division Multiplexing (FDM)
– Allows simultaneous operation of multiple services over single
pair of wires
– In POTS bandwidth is segregated into channels for each type
of traffic - power, analog voice, digital information (audio, data
& video)
Peaceful Coexistence:
Spectral Compatibility
Source: Intel Corporation
Spectral usage of three services (POTS, UADSL & home phoneline
networking) share the same line by operating at different frequencies
Spectral Compatibility
• Frequency Division Multiplexing (FDM)
– Each communications service is assigned a frequency spectrum
different from all others
– Using frequency-selective filters devices using one type of service can
exchange information without interference from other services that
communicate in another frequency band
• Frequency range
– Home network operates between 5.5MHz - 9.5MHz
• Passband filters attenuate frequencies below 5.5MHz very rapidly to
eliminate interference very rapidly to eliminate interference with
other potential services sharing wire
– Standard voice communications operate in 20Hz - 3.4kHz
– UADSL services occupy 25kHz - 1.1MHz
High Performance Encoding
• Home phoneline networking technology uses time modulation line
coding method
– Developed & patented by Tut Systems
– Increases data throughput
– Allows reliable transmission of data over the unknown cabling
system of home phone wiring at 1Mbps
– Incorporates an adaptive circuit
• Can dynamically correct for varying environmental
conditions characteristic of residential phonelines
High Performance Encoding
• Both transmit & receive circuits continually monitor line conditions
& adjust settings accordingly
– The receiver circuit of the PHY layer adapts to the varying
noise levels on the wire
– The transmitting circuit is adapting output signal strength to
match requirements of other receivers
• ‘Squelch’ algorithm sets the minimum & maximum signal levels
– The receiver can filter out extraneous noise that otherwise
might compromise data transmission & reception

network devices
View of the HPNA 2.0
Stack & Spectrum
Source: 2000 IEEE, HPNA 2.0
HPNA 2.0 System from Point of View of the
Network Stack and Frequency Spectrum
Physical Layer
• System is FDM on the same wire as used by the std. analog phone service
& splitterless ADSL
– Analog telephony uses low part of the spectrum - below 35kHz
– ADSL uses spectrum up to 1.1 MHz
– HPNA selected 4 to 10 MHz band
• Lower limit of 4 MHz makes it feasible to implement the filters
needed to reduce out-of-band interference between HPNA & ADSL
• Modeling phone networks shows the spectrum above 10 MHz to
be have wider & deeper nulls caused by reflections
• Cross talk between phone lines increases with frequency
– Analog front end is harder to implement at higher frequencies
• Choice of 4-10 MHz only overlaps a single amateur radio band
(40m) which simplifies ingress & egress filtering
Physical Layer
• HPNA 1.0 uses pulse position modulation (PPM)
– This technique adapts to the modulation rate
• HPNA 2.0 uses quadrature amplitude modulation (QAM)
– Get more throughput in the same bandwidth
– Achieve greater robustness
• Both techniques are used
– Because the channels may have very deep nulls & multiple
nulls in band
Physical Layer
• The transmitter may vary the packet encoding from 2-8 bits/symbol on a
packet-by-packet basis
– This is instead of having a fixed number of bits/symbol
– A packet header is always encoded at 2 bits/symbol so that every
receiver can demodulate at least the packet’s header
– System uses a fixed 7MHz carrier freq. & can operate at either 2 or 4
Mbaud with modulation encoding of 2-8 bits/symbol
• Base symbol rate is 2 Mbaud
– At this rate, the system has a peak data rate ranging from 4 to
16 Mbps
– Overhead reduces the actual throughput the system can
achieve
• In practice, to achieve performance equivalent to 10Base-T
Ethernet, a packet must be sent at 6 bits/symbol
Frequency-Diverse QAM
• HPNA 2.0 implements a modified version of QAM at its 2-Mbaud
rate called frequency-diverse QAM (FDQAM)
– The nature of channel nulls can be such that even rate
adaptation down to 2 bits per symbol is not sufficient to
guarantee that the packet can be received
– In a traditional QAM system, if there is an extreme null (i.e.,
one with which the equalizer can’t cope) in the band, the
system will fail to operate
• HPNA 2.0 allows for a higher performance 4-Mbaud mode, which
achieves peak data rates up to 32 Mbps & through-put above 20
Mbps
– In cases where the channel nulls are not particularly deep
Frequency-Diverse QAM
• Signal is frequency diverse, motivating the name FDQAM
– The baud rate is less than half the filter’s width
– Output signal has 2 (redundant) copies of the baseband signal
• In a traditional QAM system, a single copy of the baseband signal
is sent & received
– One copy of the signal will still make it through
• On channels with a low SNR ratio, where a large part of the
spectrum is severely attenuated, FDQAM works robustly in many
cases where uncoded QAM would fail
• Such channels are common on home phone lines
– Simplified protocol enables robust performance over time-varying
channels
– Unlike other methods of handling severe channels, in FDQAM does
not require the transmitter to have knowledge of the channel
characteristics
Frame Format
Source: 2000 IEEE, HPNA 2.0
• Frame includes
– Preamble, frame control, 802.3 Ethernet frame,
CRC16, padding and EOF (end-of-frame) sequence
Frame Format Fields
• Preamble
– 64-symbols at the beginning of the frame
– It supports robust carrier sensing & collision detection,
equalizer training, timing recovery & gain adjustment
• Frame control
– 8-bit frame type which follows the preamble
– Following the frame type is an 8-bit field that specifies the
modulation format (bits per symbol, for example)
– There are other miscellaneous control fields in frame control
including an 8-bit CRC header
Frame Format Fields
• IEEE 802.3 Ethernet frame
• CRC-16
– Cyclic Redundancy Check
– It covers the header and payload, & reduces the
undetected error rate for severely impaired networks
• Padding and EOF sequence
Frame Format - Key to Operation
• The first 120 bits of the frame are sent at the most robust 2Mbaud, 2-bits/symbol rate
• Any station able to demodulate a packet can do it at this encoding
• Even if the payload is encoded at a rate (bits/symbol) that the
receiver can’t demodulate, it will be possible to demodulate the
header
• In this situation, the receiver sends a rate request control frame
(RRCF) to the sender, asking it to reduce the number of
bits/symbol or the symbol rate
Frame Format - In Practice
• System starts out sending at 2 bits/symbol
– Unless the receiver sends an RRCF, asking for future
packets to be sent at higher data rates
– Several algorithms can be used to determine when to
send RRCFs and to estimate the channel capacity
using an approximate SNR and bit error statistics
– The rate adaptation algorithm can optimize the rate
used when sending to multicast and broadcast groups
Medium Access Control
(MAC)
• HPNA 2.0 is a CSMA/CD system
– Like the standard IEEE 802.3 Ethernet
• HPNA 2.0 introduces 8 levels of priority and uses a new collision
resolution algorithm called distributed fair priority queuing (DFPQ)
• Using the Ethernet MAC does not guarantee any real service
– Voice telephony requires a low-latency network service, and
streaming audio or video applications require a guaranteed
bandwidth service
MAC - Access Priority for
VoIP
• Different access priorities with the VoIP station having a higher
priority than best-effort file transfer traffic
• HPNA 2.0 accomplishes access priority by organizing the time
following the interframe gap into an ordered series of priority slots
– Access priority lets software define different service classes
• Such as low-latency, controlled-bandwidth, guaranteedbandwidth, best effort, and penalty
• Each uses a different priority level
MAC - Access Priority for
VoIP
• Within a given priority level, HPNA 2.0 uses a new algorithm for
collision resolution
– Each station keeps track of a back-off level & after a collision,
randomly chooses to increment the back-off level by 0, 1, or 2
– During a collision resolution cycle, stations incrementally
establish a partial ordering
– Eventually, only one station remains at the lowest back-off
level and gains access to the channel
MAC - Access Priority for
VoIP
• In practice & even on saturated networks, HPNA 2.0 behaves very
well
– Unlike traditional Ethernet it does not exhibit the capture effect
– As the offered load increases, Ethernet experiences delays of
hundreds of frame times for several percent of transmission
attempts
– When compared with the Ethernet delay, the HPNA 2.0 access
latency distribution reveals a negligible tail beyond twice the
minimum time to service each active station, even at high
offered loads
Link Layer Protocols
• Home networks using no-new-wires technology have another
problem : impulse noise
– On phone wires, impulse noise exists due to phone ringing,
switch-hook transitions, & noise coupled from the AC power
wiring
– Fortunately, the impulses tend to be short and destroy only a
single packet
– There are coding techniques that might reduce the number of
packets destroyed by impulses
– HPNA 2.0 has however chosen to use a fast retransmission
mechanism called limited automatic repeat request (LARQ)
Link Layer Protocols - LARQ
• LARQ is implemented (in software) at Layer 2
• Because it only operates on a single segment of the
network, it is very effective in hiding packet erasure from
TCP/IP
Source: 2000 IEEE, HPNA 2.0
User-level Throughput versus Impulse Noise Events/sec
Link Layer Protocols Link Integrity
• HPNA 2.0 implements a link integrity mechanism
– It can be implemented either in hardware or at low levels of a
software driver
– It provides a quick & easy way for the end user to determine if
the network has basic connectivity
– Link integrity frames are sent once per second, unless there is
traffic on the wire, in which case a reduced number of frames
may be sent

Performance Requirements
• HPNA Spec 2.0 shall be capable of achieving nominal data rates
of 10 Mbps over typical phonelines
– Based on 10 Mbps 10BaseT Ethernet network
• Coverage over phoneline networks for HPNA spec 2.0 is defined
as follows:
– Achieve full rate throughput operation over at least 80% of
home networks
– Provide ability to connect, at no specified rate, in 100% of
home networks
• Maximum internode distances are required to be greater than or
equal to the HPNA spec 1.0
Performance Requirements
• Number of nodes supported on one network greater than or equal
to HomePNA spec 1.0
• It is desirable that specifications feature adaptive capability above
and below the nominal 10 Mbps rate
– This allows optimization of throughput over the widest range of
phoneline network topologies
– This extends the coverage of homes served by HPNA spec 2.0
relative to the HPNA Spec 1.0
• It is desirable that specifications show scalability to future higher
data rates well over 10 Mbps
Compatibility Requirements
• HPNA spec 2.0 addresses the physical and logical interface point
between the phoneline and HomePNA network devices
– This ensures interoperability between Promoter's/Adopter's
home phoneline network products
• HPNA spec 2.0 should be electrically compatible with other
services
– POTS, V.90, ISDN & G.lite should coexist on the same
phoneline
Backwards Compatibility
With Earlier Specs
• HPNA Spec 2.0 specifies a mode for backward compatibility with
HPNA Spec 1.0
– The minimum requirement specifies a ‘fall back’ mode which
selects operation of HPNA Specification 1.0 for all nodes
– In a mixed network of HPNA Specs 1.0 and 2.0 nodes, all
HPNA Spec 2.0 stations should communicate at their full
10Mbps rate
• Regardless of the presence of HomePNA Spec 1.0 nodes
• Without interfering with the HomePNA Spec 1.0 nodes
Interoperability
• With HomeRF products
– HomeRF products work with HPNA-based products
• TCP/IP is used in HPNA based products & HomeRF
products fully supports TCP/IP
• Consumer requires a bridge to interface the phoneline
network to wireless HomeRF network
– HomeRF SWAP spec defines this bridging
– Vendors are currently developing future bridging
products
• With Ethernet products
– HomePNA is an Ethernet based technology and are
seamlessly interoperable
So, Can We Use
Powerlines for
Home Networking?
Powerlines are also an
Omnipresent, ‘No New
Wires’ Solution!
Powerline Home Networking
• Uses existing power & electric lines in the homes
– Quite similar to phoneline networks
• Several AC/power sockets/outlets in a home
• Powerline capabilities
– Data rates up to 10Mbps are possible
• Low cost solution
Powerline Home Networking
Pros
• Multiple power outlets can be fund in each room
• AC outlets are ubiquitous in virtually every existing home
• Powerline networking takes advantage of the unused
capacity of the power cable to transmit data over the
existing home power cabling
• Is capable of distributing data as fast as 10+ Mbps
Powerline Home Networking
Cons
Widely varying transfer response- frequency & attenuation
Different types of noise impairments at unpredictable times
RF jammers (particularly at night)
Time delay spread (multipath)
Usable bandwidth is not contiguous due to impairments or
regulations
• Channel Adaptation is required to achieve high data rates and

Noise Sources
• Switching power supplies
– Rich in harmonics with oscillator 20Kh to > 1MHz
– Conduct oscillator noise onto power line
– Frequency often varies with load
• Universal series wound motors
– Vacuum cleaners, kitchen appliances, drills
– High repetition rate impulses
Noise Sources
• Light dimmers
– Produce large impulses at 100-120 Hz
– Large 20V to 50V impulses
• Power line intercoms
– 3Vpp to 7Vpp from 150KHz to 400KHz
– Large harmonics of about 30KHz bandwidth
Powerline Technologies
• X10
– X-10 controllers send signals over existing AC wiring to
receiver modules
– X-10 power line technology transmits binary data using an
Amplitude Modulation (AM) technique
• Intellon CEBus
– Open standard that provides separate PHY layer specification
documents for communication on power lines & other media
– Data packets are transmitted by the transceiver at about
10Kbps employing spread spectrum technology
– Uses a Carrier Sense Multiple Access/Collision Detection and
Resolution (CSMA/CDCR) protocol to avoid data collisions
Powerline Technologies
• Echelon LONWorks
– Provides a peer-to-peer communication protocol, implementing
Carrier Sense Multiple Access (CSMA) techniques
• Adaptive Networks
– Utilizes a hybrid token passing media access scheme as
opposed to the peer-to-peer CSMA/CDCR schemes
Powerline Applications
• Industrial
– Utility telemetering, automated storage, factory and machine
automation, shipboard refrigerated container monitoring
• Commercial
– Point-of-sale networks, public transit vehicles, residential LAN,
vending machines monitoring
Issues to Overcome in
Powerline HN
• Immature technology
– Interference Issues
– Low Speed and Attenuation
• Lack of standards
• Lack of consumer adoption
• Regulatory issues
• There is an added cost for the extra safety isolation needed with
power connections
– This type of modem is likely to remain significantly more costly
than phoneline models but below the cost of wireless systems
