  2. More information on compromises Generation of product – As companies invest in silicon, they are less willing to consider anything that would represent a reset ofdevelopment. XSI Defends Development MBOA Defends Development 14 companies merge in MB-OFDM proposal Jan 04 Jan 05 Jan 03 Freescale proposes dual PHY XSI stop merging discussion (conf. call) XSI stop compromise negotiation with Intel Freescale not receptive to negotiate compromise Freescale/MBOA stop compromise negotiation

  3. Our History of Compromise • We have reset our programs repeatedly based upon “best technical solution” • Multibanding • Multibanding w/ OFDM • Various companies have given up developments such as Spectral Keying, frequency modulated OFDM and high rate sampling

  4. Options / Issues • Dual PHY • Maximizes market fragmentation • Does not provide benefit to customers • Complicates situation in USB/WiMedia/1394 • Complicates situation into regulatory bodies • Hybridization • Delays market • Resets silicon investments

  5. Issues With CSM Proposal • Communication is likely to be reduced to the least common denominator • It encourages fragmentation • It forces more intense use of channels, complicating the SOP situation in dense areas • It preserves DS development at the expense of other companies

  6. The Weighted Effects of Change • The number of companies who must change is asymmetric • Assuming a change, who takes the hit • OFDM silicon providers • Approximately 16 (TI, ST, Philips, Intel, Infineon, Wisair, Staccato, Alereon, etc) • DS silicon providers • Approximately 1 (Freescale) ?

  7. Conclusions • Compromise is challenging at this stage of the game. • Any path has severe market effects • It is necessary to coordinate with all OFDM authors and supporters • We hope to present a proposal in Nov.
