CE Products and Applications• Consumer electronic products will fall into one of two basic categories

• 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

CE SIG concerns regarding evaluation criteria1) 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.

Key Criteria DefinitionsCriterion Definition

Cost Financial expense to obtain a full HW and SW needed to realize UWB device.

Complexity Level of difficulty when implementing all hardware and software for a complete UWB device.

Interference robustness Ability of the UWB device to avoid performance degradation when exposed to other radio frequency signals and cause no degradation to other radio communication devices.

Data rate sets

Data rate sets are the collection of one or more data rates that are provided by a HW and SW needed to realize UWB device.

1) Ability of the system to support Higher data rates (>110Mbps) at closer ranges (<10m) 2) Ability of the system to support longer operational range (>10m) at lower data rates

(<110Mbps)

Range and coverage Distance that the radio signals are effective with a certain defined link success value, PER and packet size.

Power consumption Average power consumption of the HW and SW needed to realize UWB device.

Size Physical volume of a HW needed to realize UWB device.

Flexibility/scalability 1) Ability to later enhance the system to support higher throughput 2) Ability to implement at lower cost a UWB radio with a subset of the full system capabilities

that can interoperate with full solutions

Ranging/location awareness Capability to identify the position and the distance of UWB devices.

Time to Market The moment the full HW and SW needed to realize UWB device are available to CE companies.

Local regulatory adaptability It represents how easily the HW and SW needed to realize UWB device can be modified to comply with differing local regulations.

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

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
