Current Progress of Wireless RF Systems March 2000 Current Progress of Wireless RF Systems Capability Today Max Data BW: 6 Mbps Sources possible Native MPEG2 SDTV Decoded DV compressed 25:1 No graphics Capability in 2Q00 Max Data BW: 18 Mbps Additional sources possible Composite, S-video, component (I/P modes) XGA (30 Hz, 24 bit compressed 32:1) Capability in 2Q01 Max Data BW: 20 Mbps Additional sources possible Native MPEG2 HDTV XGA (30 Hz, 24 bit compressed 27:1) Capability in 4Q01 Max Data BW: 32 Mbps Additional sources possible XGA (60 Hz, 24 bit compressed 35:1) Mary DuVal, Texas Instruments

Summary Compression factor depends on image content March 2000 Summary Compression factor depends on image content High frequency content Bandwidth driver is computer graphics Games with high quality graphics running at 60 fps Resolutions will move toward HDTV (1280x720) Minimum Data BW needed for XGA 38 Mbps Assumes a 30:1 compression ratio Current standard bandwidth goals are too low and too late IEEE 802.11a is the only standard effort RF close at 32 Mbps data rate Requires 35:1 compression of XGA for acceptable image quality Will be available at end of 2001 (earliest) Mary DuVal, Texas Instruments
