8. doc.: IEEE 802.11-08/0130r0 Submission By 2011-12 expect strong demand for new WiFi to Stimulate Revenues Stimulate WiFI Market with speed upgrade Source: ABI research 2Q 2006 11b started at 1999, 11g started at 2003, 11n started at late 06  4 years cycle.. VHT at late 2010

9. doc.: IEEE 802.11-08/0130r0 Submission VHT A new 802.11 PHY/MAC standard should support a data rate of at least 5 Gbps. –In order to be relevant 5 years from now –To satisfy the emerging throughput-hungry applications For such a high rate there is no substitute for BW –The 60 GHz band has 7-9 GHz of unlicensed BW with quite high output power and EIRP regulatory limits. January 2008 Gal Basson (Wilocity)Slide 9

10. doc.: IEEE 802.11-08/0130r0 Submission Suggested path for VHT To define standardized modifications to the 802.11 MAC and PHY layers to operate in the 60 GHz band to achieve at least 5Gbps of over -the-air data rate. January 2008 Gal Basson (Wilocity)Slide 10

12. doc.: IEEE 802.11-08/0130r0 Submission Broad Market Potential Platforms with >20GB HDD/SSD are everywhere.11 is known to be IP over Wireless Media appliances moving to HD content Significant industry-wide incentive to drive innovation into a commoditizing market of 11n (2010+) January 2008 Gal Basson (Wilocity)Slide 12

13. doc.: IEEE 802.11-08/0130r0 Submission Compatibility Backwards compatible to earlier IEEE 802.11 standards – Triple-band WiFi Precedent:.11b/g are single band standards 11n which came later is a dual band standard. January 2008 Gal Basson (Wilocity)Slide 13

14. doc.: IEEE 802.11-08/0130r0 Submission Distinct Identity Substantially different from other 802 standards –Proposed speeds are substantially higher than the maximum 802.11n rates ~ 10 times higher –Addresses non-PAN market needs; e.g., traffic backhaul and campus/auditorium connectivity. January 2008 Gal Basson (Wilocity)Slide 14

15. doc.: IEEE 802.11-08/0130r0 Submission Technical Feasibility The availability of 7-9 GHz of unlicensed BW in the 60GHz band makes it very easy to achieve VHT. There are existing proprietary proofs of concept for wireless systems in 60GHz. –http://www.youtube.com/watch?v=3AkseaNB Ymk January 2008 Gal Basson (Wilocity)Slide 15

16. doc.: IEEE 802.11-08/0130r0 Submission Economic Feasibility Current processes more than adequate to support Giga speed Low cost 60GHz transceivers proven by several vendors VHT products must hit same cost envelope as 11n January 2008 Gal Basson (Wilocity)Slide 16
