  1. Proposed 802.15.3 Application:Wireless Home Networks Carlos Rios, 3Com

  2. Visions of the Present: The Connected Home Carlos Rios, 3Com

  3. 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 Carlos Rios, 3Com

  4. Visions of the Future: The Wirelessly Networked Home Carlos Rios, 3Com

  5. DCT-2000 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 Carlos Rios, 3Com

  6. 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 Carlos Rios, 3Com

  7. 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 Carlos Rios, 3Com

  8. 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 Carlos Rios, 3Com

  9. Device Types: Entertainment Units • Audio Visual Equipment • TVs • Set Top Boxes • Digital Videorecorders • Home Entertainment Centers • HiFi Speakers • Gaming Consoles Carlos Rios, 3Com

  10. Device Types: Personal Electronics • Walkabout Gadgets • Digital Still Cameras • Digital CamCorders • MP3 Players • Personal TVs • Movie Viewers Carlos Rios, 3Com

  11. Device Types: Telephone Equipment • POTS Connections • 2G and 3G Cellular • 2.4 Ghz Cordless Phones • Wireless VOIP Phones • Messaging Systems Carlos Rios, 3Com

  12. 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 Carlos Rios, 3Com

  13. 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 Carlos Rios, 3Com

  14. Application Requirements Carlos Rios, 3Com

  15. Application Requirements: System Carlos Rios, 3Com

  16. Application Requirements: PHY Carlos Rios, 3Com

  17. Application Requirements: MAC Carlos Rios, 3Com

  18. 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 Carlos Rios, 3Com
