Summary Qualcomm proposal builds on existing 802.11a,g,e design November 2004 Summary Qualcomm proposal builds on existing 802.11a,g,e design 802.11n can enable new markets & applications: Multimedia distribution in the home Enhanced enterprise applications (e.g. VoD, Video Conf.) These applications require: High throughput  SS/ES, ACF, rate feedback High QoS  SS/ES, ACF, rate feedback Maximized range  ES Maximum spectral efficiency  ES SS/ES + rate feedback + ACF meet the requirements associated with these new markets & applications: Highest network capacity: greater than 100 mbps above the MAC inside 30 m (20 MHz, 2x2, 5 GHz) Reliable coverage QoS: Less than 50 ms latency with “ZERO packet loss” PHY techniques proven in FPGA-based prototype John Ketchum, et al, Qualcomm

Throughput Comparison November 2004 Throughput Comparison 0 dB: 120 m 10 dB: 60 m 20 dB: 30 m 30 dB: 15 m 37.5 dB: 10m SGI-52: 52 data subcarriers with short guard interval Results given with closed loop rate control SS-STBC can achieve 120Mbps at 30m (20dB) ES has > 6 dB advantage over other at 150 Mbps PHY throughput At 30 m (20 dB) ES has >50% PHY t’put advantage over others John Ketchum, et al, Qualcomm

Goals Maximize Throughput, QoS, and Spectral Efficiency November 2004 Goals Maximize Throughput, QoS, and Spectral Efficiency Minimize complexity and assure backward compatibility Provide balance between TTM needs and 11n design longevity economics John Ketchum, et al, Qualcomm
