doc.: IEEE /0848r0 Submission Comments received From the “concerns” doc (TG3c July 7 th ): “VHT60 PAR: may need further clarification These including: 1.“Maintain the user experience” (in Scope)” So, what is meant by “user experience”? January 2008 Gal Basson (Wilocity)Slide 2

doc.: IEEE /0848r0 Submission user experience We all know b, g, a and n is much more than these standards. The “ user experience” is defined by the ecosystem created by the additional standards. –As much as the PHY and the MAC are important, they are a small part of the whole user experience. And, Wi-Fi Certification enables consumer confidence in interoperability, coexistence and basic operation. January 2008 Gal Basson (Wilocity)Slide 3

doc.: IEEE /0848r0 Submission Basics Wireless LAN- Based on Ethernet Implied bridging between and at the low level protocol –3 to 4 addresses: Source, BSS ID, (BSS ID) Destination MAC Address format is driven from the Unscheduled transmission –Unreliable Media Medium access is based on carrier sense. Almost 100% of the traffic on Wireless LAN is TCP-IP January 2008 Gal Basson (Wilocity)Slide 4

doc.: IEEE /0848r0 Submission LAN ecosystem is much more than a PHY So what is the wireless LAN ecosystem –What does it takes to run wireless LAN at 60G? One Example: –I have a client running n with i security, e QOS, and k Radio management for Traffic balancing –I want to seamlessly move from my wireless LAN 5G to the Wireless LAN VHT (60G), maintaining the same security agreement and the same QOS level all while enabling the system administrator to perform network balancing January 2008 Gal Basson (Wilocity)Slide 5

doc.: IEEE /0848r0 Submission The alphabet soup d (approved 2001) – International support (Roaming, country to country, also includes c), Widely deployed h (approved 2003) – Spectrum managed 5GHz, DFS (Dynamic Frequency Selection), TPC (Transmit Power Control) Widely Deployed i (approved 2004) – Enhanced Security baseline for every product WFA) e (approved 2005) – Quality of Service, parts of it widely deployed k (approved 2008) – Radio measurements helpful for load balancing, network maintenance etc.. (To be deployed at 2009) w (Ongoing) – Security for management frames (expected to be deployed in 2009) January 2008 Gal Basson (Wilocity)Slide 6

doc.: IEEE /0848r0 Submission The alphabet soup s (Ongoing) – mesh networking r (Almost published) – Fast roaming u (Work in progress) – Advertising under 802 before association v (Work in progress) - Network management z (Work in Progress) – DLS (Direct Link Setup) aa (work in Progress) - Video Transport Stream More: –802.11j – Japan support –802.11y G spectrum support January 2008 Gal Basson (Wilocity)Slide 7

doc.: IEEE /0848r0 Submission The Market/Environment According to ABI Research, demand for WLAN ICs is expected to grow at a 34% Compound Annual Growth Rate (CAGR) from 2007 to 2012 and Wi-Fi IC sales are expected to exceed 1 Billion units per year in Wi-Fi Alliance certification to a/b/g/n ensures interoperability and has enabled wide market adoption January 2008 Gal Basson (Wilocity)Slide 8

doc.: IEEE /0848r0 Submission LAN ecosystem is much more than a PHY Can we implement Wireless LAN over c ? –Sure we can, but at what cost? One Example: –I have a client running n with i security, e QOS, and k Radio management for Traffic balancing –I want to seamlessly move from my wireless LAN to the Wireless LAN, maintaining the same security agreement and the same QOS level all while enabling the system administrator to perform network balancing. –While it is possible to reproduce all of these features in c, it seems to be a negative ROI, given these features already exist in January 2008 Gal Basson (Wilocity)Slide 12
