1 Doc:IEEE 802.15-00/0150r0 Submission May 2000 Carlos Rios, 3Com Proposed 802.15.3 Application: Wireless Home Networks

2 Doc:IEEE 802.15-00/0150r0 Submission May 2000 Carlos Rios, 3Com Visions of the Present: The Connected Home

3 Doc:IEEE 802.15-00/0150r0 Submission May 2000 Carlos Rios, 3Com Consumer Device Connectivity Today Consumer devices are now communicating with each other in the home –PCs to PCs and peripherals –Data Gateways to PCs –Entertainment Gateways to Set Top Boxes –Personal Electronics to PCs and peripherals –Personal Electronics to TVs, VCRs and STBs –Home Entertainment Units to each other Wired connections: USB, 1394, Ethernet, Analog

4 Doc:IEEE 802.15-00/0150r0 Submission May 2000 Carlos Rios, 3Com Visions of the Future: The Wirelessly Networked Home

5 Doc:IEEE 802.15-00/0150r0 Submission May 2000 Carlos Rios, 3Com Consumer Device Connectivity Tomorrow All devices can and will communicate wirelessly –No interconnection cables All devices can be networked –All can talk to each other One single network in the home –Flexible, scalable and full featured Devices remain consumer devices –Extremely easy to use –Inexpensive wireless connectivity DCT-2000

6 Doc:IEEE 802.15-00/0150r0 Submission May 2000 Carlos Rios, 3Com The Wirelessly Home Area Network Application Enable the wireless interconnection of electronic devices within the home –Low and high speed throughput –Real time and non-real time data –Support prioritization and guaranteed bandwidth, latency –Multiple simultaneous connections –Enable coexistence, interoperability, coordination between all home devices –Coexist and interoperate with “visiting” or legacy devices designed to other standards

7 Doc:IEEE 802.15-00/0150r0 Submission May 2000 Carlos Rios, 3Com Device Types: Residential Gateways Entry point into the home for Data and Video –Satellite TV Decoder –Cable TV Decoder –Cable Modem –DSL Modem –“Broadband Wireless” Modem –3G Phones

8 Doc:IEEE 802.15-00/0150r0 Submission May 2000 Carlos Rios, 3Com Device Types: PCs and Peripherals Computing devices and attachments –Desktop PCs –Laptop PC, likely brought home from work –High speed color printer –Scanner –Copier –PDA –PC Camera

9 Doc:IEEE 802.15-00/0150r0 Submission May 2000 Carlos Rios, 3Com Device Types: Entertainment Units Audio Visual Equipment –TVs –Set Top Boxes –Digital Videorecorders –Home Entertainment Centers –HiFi Speakers –Gaming Consoles

10 Doc:IEEE 802.15-00/0150r0 Submission May 2000 Carlos Rios, 3Com Device Types: Personal Electronics Walkabout Gadgets –Digital Still Cameras –Digital CamCorders –MP3 Players –Personal TVs –Movie Viewers

11 Doc:IEEE 802.15-00/0150r0 Submission May 2000 Carlos Rios, 3Com Device Types: Telephone Equipment POTS Connections –2G and 3G Cellular –2.4 Ghz Cordless Phones –Wireless VOIP Phones –Messaging Systems

12 Doc:IEEE 802.15-00/0150r0 Submission May 2000 Carlos Rios, 3Com Why Networked? Coordination mitigates the Train Wreck –802.11b WLANs will enter the home this year –802.15.3 multimedia apps target the home –Wherefore wireless VOIP phones? –Still have Bluetooth, HomeRF, 2.4 GHz cordless phone, microwave oven interferors Networking is the logical extension of –Necessary device coexistence –Desirable device interoperability Need not add much cost

13 Doc:IEEE 802.15-00/0150r0 Submission May 2000 Carlos Rios, 3Com The General Application Idea A “Wireless Network Coordinator” (WNC), acts as a home radio spectrum traffic cop The WNC controls transmissions from all 802.11b and 802.15.3 devices in the home, assigning priorities and allocating bandwidth as needed Devices associate and communicate directly with each other Signaling occurs at data rates exceeding 40 Mbps, providing multiple simultaneous links 802.15.3 rate scales down to 802.11b –The WNC is an 802.11 point coordinator

14 Doc:IEEE 802.15-00/0150r0 Submission May 2000 Carlos Rios, 3Com Application Requirements

15 Doc:IEEE 802.15-00/0150r0 Submission May 2000 Carlos Rios, 3Com Application Requirements: System

16 Doc:IEEE 802.15-00/0150r0 Submission May 2000 Carlos Rios, 3Com Application Requirements: PHY

17 Doc:IEEE 802.15-00/0150r0 Submission May 2000 Carlos Rios, 3Com Application Requirements: MAC

18 Doc:IEEE 802.15-00/0150r0 Submission May 2000 Carlos Rios, 3Com Summary One single, fat wireless pipe to service home connectivity needs Any and all gateway, computing, CE, and telephony devices share the pipe in harmony The wireless connectivity needs to be robust, full featured and extremely easy to use The wireless connectivity needs to coexist with legacy technology The wireless connectivity needs to be inexpensive
