3. Motivation • Observations: • Existing and upcoming technologies may already satisfactorily address basic WPAN needs • Features that provide added utility beyond existing WPAN technologies must be identified • 60 GHz unlicensed spectrum has already attracted the interest of other regulatory agencies internationally • Challenges: • mmW technology will impact solution cost • Exploit unlicensed bands with large amounts of available spectrum to realize higher capacity, cost-competitive solutions • Purpose of this presentation: • Help frame key questions for the mmW Interest Group to address collectively S. David Silk, Motorola

4. * Graphic is an excerpt from reference [1] and has been modified for this submission Application Input • What applications can be enabled and exploited by 60 GHz? • Challenges: • mmW technology will impact solution cost • Differentiate from other technologies to address non-overlapping application spaces, perhaps identify a variety of niche applications addressed by different device classes mandating at least one common mode of operation between the device classes • Exploit and balance RF spatial processing such as diversity, directive antennas, or circular polarization to mitigate the effects of multipath propagation to ease and perhaps obviate the need for an equalizer WPAN region 1000 fixed wireless broadband region UWB region 100 UWB Potential 60 GHz region 802.11a 10 802.11b Throughput Capacity [Mbps] 802.15.4 WLAN region 1 UWB reach out with less data, but with location (SG4a) 0.10 1k 0 10 20 30 40 50 60 70 80 90 100 Range [m] S. David Silk, Motorola

5. Conclusions • To date several submissions have addressed: • PHY requirements [2] • Application concepts [3] • Fixed wireless access point-to-point • Inter-vehicle communication • In-home video distribution • Regulator issues and spectral management • Japanese regulations [3] • European regulations [4] • To progress the IG to a SG, analyses of the application space and market requirements to identify critical system parameters are needed • The IG must differentiate 60 GHz from competing and upcoming technology and identify an unique set of criteria (as an example data rate requirements based on identified applications) S.
