2. Consumer Electronic Applicationsand Systems Requirements for Alternative PHY Enhancements to IEEE P802.15.3 Response to the SG3a CFA James D. Allen, Appairent Technologies, Inc. Mark Schrader, Eastman Kodak Co.

3. Requirements for PHYs beyond TG3 • Sony-sama did an excellent job presenting the Consumer Equipment (CE) requirements in document 02/043r0. • This presentation (02/102r0) focuses on our view of the systems and applications needs for those CE devices, and markets. James D. Allen, Appairent Technologies, Inc. Mark Schrader, Eastman Kodak Co.

4. The Wireless CE Model • Assumptions: • TG3 and it’s family of PHYs shall be uniquely capable of winning in the portable CE device and home entertainment industry. • QoS • Low Power and Advanced Power Management • Ad hoc Security • Cost • Large number of Nodes • ….. James D. Allen, Appairent Technologies, Inc. Mark Schrader, Eastman Kodak Co.

5. The Wireless CE Model (cont.) • Assumptions: • When sufficient numbers of portable devices go home, the value spreads horizontally from portability to entertainment to broadband access. • Strategies that apply just to one of these CE applications confuses and divides the segment. (e.g. just cameras, or just TV distribution.) James D. Allen, Appairent Technologies, Inc. Mark Schrader, Eastman Kodak Co.

6. The Wireless CE Model (cont. 2) • Therefore… …alternative PHYs must meet critical requirements of a wide range of CE devices and the applications in which they may be used. • For example, consider the following criteria for any WPAN technology: James D. Allen, Appairent Technologies, Inc. Mark Schrader, Eastman Kodak Co.

7. Low Power Density • Many accessory devices and formats require low power densities and sizes • Memory Stick • SD Card • Media Card • Since these interfaces are limited in bandwidth, cards must also have room/power for memory, and communications CPU capabilities. Therefore system power and power density is critical. It is important to consider more than just the PHY alone. James D. Allen, Appairent Technologies, Inc. Mark Schrader, Eastman Kodak Co.

8. Small Devices and Antennas • Size and area are important to designers and users. • Antennas must be as small as possible • Should be consistent with small consumer devices and memory card formats (e.g. a 1x2 inch antenna may not be consistent with a SD format) • Must be insensitive to close body and hand proximity • Must have omni and directional antenna options • Must be easily embeddable by OEMs, into unintentional radiators. • Must be consistent with “PDA’s in shirt pocket safety issues. James D. Allen, Appairent Technologies, Inc. Mark Schrader, Eastman Kodak Co.

9. Need to Support Multiple Moving Piconets • Two or more networks must be able to operate at the same time in the same space. • The customer will not have control of all personal spaces. • e.g. theme parks, kiosks • Outside the home uses • Devices must continue to communicate regardless of pedestrian movement or change in relative signal strength. James D. Allen, Appairent Technologies, Inc. Mark Schrader, Eastman Kodak Co.

10. Need to be International and Outdoor Capable • Portable CE devices are portable internationally. • Must be able to transport and use without restrictions or globalization. • Need to address IEEE 802 regulatory issues (what ever they are ) James D. Allen, Appairent Technologies, Inc. Mark Schrader, Eastman Kodak Co.

11. Must be Peer-to-Peer Capable. • Otherwise users can’t share images at will. • Limits market for digital imaging sharing products. James D. Allen, Appairent Technologies, Inc. Mark Schrader, Eastman Kodak Co.

12. A/D X LNA Filter PHY MAC WaveletGenerator Synthesizer OSC Shall be Capable of Operating in the Common 22Mbps QPSK Mode • Shown possible by Rofheart proposal with minimum impact in document 00/195r8. Source: 00/195r8 James D. Allen, Appairent Technologies, Inc. Mark Schrader, Eastman Kodak Co.

13. Shall be Capable of Operating in the Common 22Mbps QPSK Mode • This allows all TG3 systems to coordinate. Makes sure all TG3 systems can talk at some level (backward compatibility) • Allows un-allocated PHYs to operate in international market prior to allocation. • Sets expectation for future PHYs • Otherwise the market message fragments (reference BT1 and 2, and .11 scenarios.) James D. Allen, Appairent Technologies, Inc. Mark Schrader, Eastman Kodak Co.

14. Range • New PHYs should extend the possible range, and certainly reliability: • Range and robustness is more visible to consumers than speed (which they expect). • Tradeoffs/expectations need to be simple and clear to the user before purchase. • DVB 3 walls, 3 meters between walls is good target. • Low geographical hystersis. James D. Allen, Appairent Technologies, Inc. Mark Schrader, Eastman Kodak Co.

15. Initial Connect time must be 1 second or less. • User focus groups - • 1 second or less connect time for many portable applications • 10 -15 second transfer time applies normally to a subset of a memory card. • DPOF allows marking of individual files. • Discs are not normally filled at one session but marketing data was not available, e.g. MP3. James D. Allen, Appairent Technologies, Inc. Mark Schrader, Eastman Kodak Co.

16. Coexistence • Needs to tradeoff issues of coexistence consistent with range and applications. • If range is small, and Personal Operating Space is small, the resulting device densities should be considered. • Channel plans or other methods may be sufficient means for coexistence. • The tradeoff should be developed from the applications. James D. Allen, Appairent Technologies, Inc. Mark Schrader, Eastman Kodak Co.

17. Must be More Than one Source of the Technology. • There needs to be more than one source of the technology • Proposals should agree to RAND IP rules as part of their proposal so intentions are clear. James D. Allen, Appairent Technologies, Inc. Mark Schrader, Eastman Kodak Co.

18. Conclusion • There are many requirements that extend past the need for speed. • The Issues, as presented, indicate the other aspects important to the systems design for CE devices and need to be considered by the pending proposals.
