doc.: IEEE /534r0 Submission July, 2003 Wataru GohdaSlide 2 Outline Application Requirements for Audio/Video Application Requirements for Voice General HT Requirements
doc.: IEEE /534r0 Submission July, 2003 Wataru GohdaSlide 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
doc.: IEEE /534r0 Submission July, 2003 Wataru GohdaSlide 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
doc.: IEEE /534r0 Submission July, 2003 Wataru GohdaSlide 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
doc.: IEEE /534r0 Submission July, 2003 Wataru GohdaSlide 6 Summary These “application requirements” have to be met by whatever HT MAC/PHY combinations are proposed for usage models.
