6. doc.: IEEE 802.15-02/137r0 Submission March, 2002 Jim Meyer, Time Domain CorporationSlide 6 Functional Requirements - Bandwidth Voice/Audio Applications Voice services – 10 Kbps High quality VOIP/Digital Audio –128 Kbps streaming audio –384 Kbps surround sound Broadband Data Applications Today’s typical client ~ 1Mbps Future access requirements up to 10Mbps Video Applications TodayFuture. Cable & Satellite Video 2-10 MbpsUp to 10 Mbps DVD 10 Mbps HDTV19.2 Mbps Digital Camcorder27 Mbps<15 Mpbs

7. doc.: IEEE 802.15-02/137r0 Submission March, 2002 Jim Meyer, Time Domain CorporationSlide 7 Functional Requirements – Capacity & Channelization Economics dictate multiple units per cell –Video and Data applications 4 Units per cell – non overlapping channels –~15 Mbps per unit today –30+ Mbps per unit in the future Phased deployment options –Data and voice services only 8 units per cell –~ 1 Mbit Capacity model must also include –Individual unit ad-hoc connections Cameras Game interfaces MP3 devices –Other fixed networks Video/Audio distribution Total required capacity of 300 Mbps –Includes adjacent cell interference

8. doc.: IEEE 802.15-02/137r0 Submission March, 2002 Jim Meyer, Time Domain CorporationSlide 8 Functional Requirements – Security Each Unit must have a secure network The network must provide security for: –Delivered content Broadband data Voice content –Internal Content Ad-hoc Permanent Network operators will provide their own security - Video & Audio –“Studio Approved” conditional access technologies exist –Fighting the security battle is not worth the time to market cost –Equipment manufactures use their CA as a differentiator Security doesn’t need to be added at the MDU

9. doc.: IEEE 802.15-02/137r0 Submission March, 2002 Jim Meyer, Time Domain CorporationSlide 9 Functional Requirements – Mobility While the focus of MDU multimedia distribution is viewed as a fixed device proposition today… –Future video display devices will be portable Microsoft Mira portable display technology CE manufactures are aggressively pursuing video tablets Portable connected devices must be compatibleProjector Digital Camera MP3 Player Laptop TV Camcorder Printer

10. doc.: IEEE 802.15-02/137r0 Submission March, 2002 Jim Meyer, Time Domain CorporationSlide 10 Functional Requirements – Co-existence Multiple networks and other wireless CE devices will exist in the home –WiFi, Bluetooth, 2.4 & 5 Ghz phones etc will be part of the environment Incumbent networks will not be discarded –If we don’t work with the old network, we're not deployable Service providers may combine networking technologies –In unit gateways may utilize 2.4 or 5 GHz hand sets

11. doc.: IEEE 802.15-02/137r0 Submission March, 2002 Jim Meyer, Time Domain CorporationSlide 11 Summary The MDU/MTU market is large –It accounts for a large percentage of homes High data rates will be required in the future – 300 Mbps Demands cell re-use and high spatial capacity Individual unit security is a must Co-existence may be more important –Incumbent networks will not be discarded – it may be your neighbors! If we don’t work with the old network, we're not deployable Success depends upon also meeting the key metrics for consumer multimedia devices: QoS Power consumption Footprint Cost
