  2. Outline • Application Requirements for Audio/Video • Application Requirements for Voice • General HT Requirements Wataru Gohda

  3. Application Requirements for Audio/Video • High Bandwidth • 24Mbps for HDTV MPEG2 Stream • 7Mbps for SDTV MPEG2 Stream • At least 3 HDTV streams at the same time • QoS capability • High reliability and low jitter • Synchronization << 1us • Mostly for high end audio requirement Wataru Gohda

  4. Application Requirements for Voice • Power save feature • Max and Average(*) battery usage for existing Cellular Phone • Max 7.5hours, Ave 3.5hours for talk time • Max 16days, Ave 7.4days for standby time • Fast roaming capability • QoS capability • High reliability and low jitter • *simple average based on spec value of each model in Web site Wataru Gohda

  5. General HT Requirements • Backward compatibility • Compatibility with 11a/g PHYs is highly desirable • Forward compatibility • As the FCC/Japan MPT/Other regulatory bodies would allocate another unlicensed spectrum, we want to be able to adapt the system for use in that band quickly • Coexistence • Home AV requirements must compatibly coexist with Public Space, Enterprise deployments Wataru Gohda

  6. Summary • These “application requirements” have to be met by whatever HT MAC/PHY combinations are proposed for usage models. Wataru Gohda
