1 Doc:IEEE 802.11-00/093 Submission May 2000 Carlos Rios, 3Com Proposed Application for HRbSG Technology: Wireless Home Area Networks

2 Doc:IEEE 802.11-00/093 Submission May 2000 Carlos Rios, 3Com Visions of the Present: The Connected Home

3 Doc:IEEE 802.11-00/093 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 802.11-00/093 Submission May 2000 Carlos Rios, 3Com Visions of the Future: The Wirelessly Networked Home

5 Doc:IEEE 802.11-00/093 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 802.11-00/093 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 802.11-00/093 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 interferors Networking is the logical extension of –Necessary device coexistence –Desirable device interoperability Will not add much cost

8 Doc:IEEE 802.11-00/093 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 may occur at data rates exceeding 40 Mbps, providing multiple simultaneous links HRbSG rate scales down to 802.11b –The WNC is an 802.11 point coordinator

9 Doc:IEEE 802.11-00/093 Submission May 2000 Carlos Rios, 3Com Application Requirements

10 Doc:IEEE 802.11-00/093 Submission May 2000 Carlos Rios, 3Com Application Requirements: System

11 Doc:IEEE 802.11-00/093 Submission May 2000 Carlos Rios, 3Com Application Requirements: PHY

12 Doc:IEEE 802.11-00/093 Submission May 2000 Carlos Rios, 3Com Application Requirements: MAC

13 Doc:IEEE 802.11-00/093 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
