May 2000 doc. : IEEE 802. 11 -00/074 Technical Feasibility of CCK Extensions for HRb Mark Webster and Carl Andren Intersil Corporation May 2000 Submission 1 Mark Webster, Intersil

May 2000 doc. : IEEE 802. 11 -00/074 Conform to Current Regulatory Rules • USA’s FCC, Japan’s MPT and Europe’s ETSI • Minimize the time-to-market by conforming to the current FCC rule set. • Avoid a lengthy FCC debate with an uncertain outcome. • Avoid burdening 802. 11 with the need to lobby the FCC to assume a new position different than the NPRM. • Avoids opening the 2. 4 GHz band up to detrimental, under-regulated signals. Submission 2 Mark Webster, Intersil

May 2000 doc. : IEEE 802. 11 -00/074 Target at Least 33 Mbps • 22 Mbps HRb may not provide adequate throughput rates for desired applications. • 33 Mbps appears to provide significantly higher throughputs. • HRb standard should provide a path to data rates higher than 22 Mbps, if feasible. • Avoids a need to return the standards process yet again.

May 2000 doc. : IEEE 802. 11 -00/074 CCK Extensions for HRb • High-data-rate extensions to the CCK waveform exist which are compatible with the FCC rules (spreading codes). • High-data-rate extensions to the CCK waveform exist which reach a minimum of 33 Mbps. • The CCK extensions perform well in thermal noise (AWGN). • We are currently analyzing the performance for multipath and multipath-plus-noise.
