— Multi-PC/household growth (U.S.): 15M (1998) to 26M(2003) *
w Increasing Internet usage
— Internet usage growth (U.S.): 20% (1997) to 47% (2001) **
w Demand for Broadband
— Broadband penetration growth (U.S.): less than 1M (1998) to
more than 15M (2002) ***
w Info-appliance Invasion
— Increased Sharing of digital content inside the home

History Repeats Itself Again...
w Television
— There was a time when one television set per home was
considered a luxury
— Today 76% of US households have two or more television
sets
— Three factors contributed to multiple TV ownership
– Purchase of newer/bigger/ better television
– Additional television to reduce conflicts over TV use
– Television in bedroom / kitchen
— Replace the word “TV” with “PC” and history repeats itself
again!

Broadband Based or
Digital Modems RGs
w Broadband termination device that has incorporated the
necessary routing functions within one device
w ADSL or cable termination device with routing capabilities
w Digital modem that has evolved to incorporate the
necessary functionality to be a RG
w Gateway is sold in conjunction with DSL services
— Can be partially or completely subsidized
— Consumer installs the gateway
– The service provider saves the cost of a truck roll
w Not dependent upon a PC
®
www.xilinx.com
Broadband Centric or
Digital Modems RGs
w Built to support one specific home networking technology
— HomePNA, Ethernet, USB or wireless
— Future technology advancements require buying another
gateway & reconfiguration of the home network
w Examples
— 2Wire Inc. - Product: HomePortal
– Provides support for both HomePNA & HomeRF solutions
– Platform for PC networking, communications convergence &
distributed entertainment content
– Remotely manageable
— Cayman ADSL 3220H router/RG
— Cisco uBR924 Cable router/RG

RG - An Incremental Deployment
From Digital Modems to Residential Gateway
®
www.xilinx.com
Home Networking is Here!
®
www.xilinx.com
First Generation RGs
w Not IP based devices & have low bandwidth
w Types
— Digital set-top box RGs
– Broadcast TV into the home
— Utility-centric RGs
– Enable automated meter reading (AMR), energy optimization,
home automation, management & monitoring
— PCs
— Gaming consoles
®
www.xilinx.com
Second Generation RGs
w Devices that bridge one WAN pipe to one LAN connection
w Configurations include
— Digital modems connected to a PC
— Or, stand alone devices with the intelligence to handle all of
these functions without the aid of a PC
w Conduct majority of routing functions & IP address mgmt
w Broadband access termination devices with integrated
LAN hubbing routing functionality
— Example: Cayman’s ADSL 3220H router/RG
— Example: General Instruments-Motorola’s DCT 5000+
Advanced Interactive Digital Consumer Terminal
®
www.xilinx.com
Second Generation RGs
w PC-based architecture RG
— Example: Ericsson’s E-Box
w Set-top box RG
— Has the necessary home routing functionality
— Example: Next level Communications N3 RG
w Smart phones
— Example: Global Converging Technologies or Home
Wireless Networks, Cisco, Alcatel, Nokia, Nortel, Ericsson
w Targeted by service providers & equipment OEMs for
wide scale deployment as RGs in the next 2-3 years
®
www.xilinx.com
Third Generation
w Multi-service home gateways
w Have capabilities to terminate
— Multiple types of WAN connections (wireless, DSL, cable)
— Multiple LAN connections (Ethernet, RF, HPNA, powerline)
w More expensive given the high degree of modularity
w Will be owned by the consumer
— Service providers do not inherently share CPE equipment
— Unless channel & pricing model changes this is not realistic
w Example
— Sharegate’s RG
®
www.xilinx.com
Third Generation
w These devices do not exist today but will evolve based on
products available today
w Features
— Modular in design
— Multiple WAN termination of media types such as wireless,
xDSL or cable supported
— Multiple LAN/home networking technologies supported
– Less apt to becoming obsolete with future technology changes
— Deliver telephony/voice services
— Easier to set up
— Remote management is possible

phonelines
— Depends on in-home network technologies
– Phoneline, powerline, Ethernet, IEEE-1394/Firewire, HomeRF,
Bluetooth, wireless LANs (IEEE-802.11 & HiperLAN2)
