2. doc.: IEEE 802.11-07/2587r0 Submission September 2007 Gal Basson (Wilocity)Slide 2 Abstract This presentation discusses some possible future (5-10 years out) applications that require very high throughput (above 1 Gbs) and are beyond the capability of 802.11n.

3. doc.: IEEE 802.11-07/2587r0 Submission Terminology Application – a source or sink of wireless data that relates to a particular type of user activity Usage Model – A specification of one or more applications and environments from which a simulation scenario can be created once the traffic patterns of the applications are known. Usage models are created to encompass use cases. Latency- The time from when a packet was sent till it has been received w/o an error September 2007 Gal Basson (Wilocity)Slide 3

9. doc.: IEEE 802.11-07/2587r0 Submission Summary In 5-10 years, the need for Gbps-WLAN is obvious –Various applications that exist today + more we can’t think of now… Holograms ???? Who knows.. Need 10X over 11n to be still relevant in 10 years –3-5Gbps Is there a substitute to higher BW ? –Is it reasonable to expect a factor of 5-10 increase in data rate in the 5 GHz band used by two prior 802.11 standards? –Increasing bandwidth is the most straightforward method for increasing rate, as we do not get unlimited robust gains from spatial multiplexing.
