Technical Feasibility of CCK Extensions for HRb Month 1998 doc.: IEEE 802.11-00/xxx May 2000 Technical Feasibility of CCK Extensions for HRb Mark Webster and Carl Andren Intersil Corporation May 2000 Mark Webster, Intersil Mark Webster, Intersil

Conform to Current Regulatory Rules May 2000 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. Mark Webster, Intersil

May 2000 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. Mark Webster, Intersil

May 2000 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. Mark Webster, Intersil
