Consumer Electronic Industry Requirements for TG3a Alt PHY Various, Panasonic/Philips/Samsung/Sharp/Sony

Contents • Purpose • The CE opportunity for TG3a • Concerns regarding evaluation criteria • CE companies prioritization of criteria • CE perspective of criteria requirements • Request for additional data • Conclusion Various, Panasonic/Philips/Samsung/Sharp/Sony

Background and Purpose • Five leading consumer companies (Panasonic, Philips, Samsung, Sharp, Sony) who share common interests in adopting TG3a Alt PHY in CE applications have formed a CE Special Interest Group • The CE SIG does not endorse nor support a particular Alt PHY proposal • The purpose of the CE SIG is to provide TG3a with a consensus view of requirements and criteria priorities on Alt PHY for consumer electronics applications • Our purpose is to assist TG3a in selection of an Alt PHY which can be successful in consumer markets Various, Panasonic/Philips/Samsung/Sharp/Sony

The CE opportunity Global Demand Forecast for home electric products • As the above industry forecasts show, the CE market represents a very large opportunity for a multimedia capable wireless PAN technology such as Alt PHY (PC forecast included for completeness) Various, Panasonic/Philips/Samsung/Sharp/Sony

CE Products and Applications • Consumer electronic products will fall into one of two basic categories Home Theatre Portable • Typically static, unmoving • Medium/large cabinet size • AC powered • Require highest isochronous throughputs (e.g. HDTV) • Require very high QoS (equivalent to wired QoS) • Applies to Portable devices used in or outside home • Typically battery powered, but occasionally AC powered • Small cabinet size • Highest speeds needed for asynchronous transfer rather than isochronous Characteristics • Television • Video recording device (PVR, VHS, DVD-R) • Set-top Box, Media server • Stereo audio player • Surround sound audio • Video Camera • Audio player (MP3, CD) • Digital still camera • Cellular phone • Notebook PC • PDA Examples Various, Panasonic/Philips/Samsung/Sharp/Sony

CE SIG concerns regarding evaluation criteria 1) Path Loss: The channel models do not have a path loss exponent for typical environments such as family room -- this makes it impossible to determine if performance will meet CE needs. 2) Link Success:A 90% link success rate is used as the benchmark for simulations. For CE applications, higher success rates such as 95% or 98%+ are required. CE SIG would like to see analysis for performance at higher link success rates, such as 95% and 98%. 3) Channel Models: The channel models may not represent effectively true propagation in real home environments, making it difficult to assess actual CE application performance. Especially for Home Theatre applications, device placement may be near wall or inside an AV cabinet/furniture. We would like to see analysis taking better account of fading effects and cabinet penetration. 4) Packet Size and PER: Current benchmarks for simulation are 1024byte and 8% PER. Consumer-AV applications require very low residual error rates (e.g. 1 MPEG packet loss in 2 hours). To meet this, smaller packet sizes and potentially lower PER may be needed -- additional simulation data with a variety of packet sizes and PERs is desirable. 5) Interference/SOP distance: The distance separating interferers or uncoordinated piconets is relative to an Alt PHY proposal’s maximum range rather than an absolute distance -- this makes comparison difficult.

CE perspective on criteria requirements Various, Panasonic/Philips/Samsung/Sharp/Sony

Request for additional data • CE applications have tough requirements for link success rate: • We would like Alt PHY proposals to provide analysis or comments to demonstrate performance for higher link success rates e.g. 98% • Home Theatre CE applications require very low error rates (e.g. one MPEG loss in >2 hours). Benchmark packet size/PER values for Alt PHY evaluation (1024byte/8%) may be too high for such CE applications. We would like to see simulation data for: • lower packet error rates: <5% and smaller packet sizes: e.g. 256byte and 512byte • CE SIG would like simulations/analysis to incorporate realistic propagation conditions for home: • A path loss exponent other than free space realistic for a family room environment • Consideration taken of shadow fading environments • Consideration taken of typical, poor device placement such as near walls or inside AV cabinets/furniture Various, Panasonic/Philips/Samsung/Sharp/Sony

Conclusion • Integration in CE products represents a very large market opportunity for TG3a Alt PHY • Five major CE companies have come together to jointly present our view on criteria requirements and priority for TG3a to succeed in the CE industry • Our only purpose is to assist IEEE802.15 TG3a in selecting a PHY which is best able to succeed in CE • It is important for Alt PHY to meet the requirements presented herein in order for widespread successful adoption by the major CE companies • If Alt PHY is unable to meet the requirements presented herein, it risks not being adopted by the CE industry, or being adopted only in a limited set of applications Various, Panasonic/Philips/Samsung/Sharp/Sony
