1 doc.: IEEE 802.11-08/0848r0 Submission January 2008 Gal Basson (Wilocity)Slide 1 802.11 Wireless LAN user experience Date: 2008-07-13 Authors:

2 doc.: IEEE 802.11-08/0848r0 Submission Comments received From the 802.15 “concerns” doc (TG3c July 7 th ): “VHT60 PAR: may need further clarification These including: 1.“Maintain the 802.11 user experience” (in Scope)” So, what is meant by “user experience”? January 2008 Gal Basson (Wilocity)Slide 2

3 doc.: IEEE 802.11-08/0848r0 Submission 802.11 user experience We all know 802.11b, 802.11g, 802.11a and 802.11n. 802.11 is much more than these standards. The “802.11 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 802.11 user experience. And, Wi-Fi Certification enables consumer confidence in interoperability, coexistence and basic operation. January 2008 Gal Basson (Wilocity)Slide 3

4 doc.: IEEE 802.11-08/0848r0 Submission 802.11 Basics Wireless LAN- Based on Ethernet Implied bridging between 802.11 and 802.3 at the low level protocol –3 to 4 addresses: Source, BSS ID, (BSS ID) Destination MAC Address format is driven from the 802.3 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

5 doc.: IEEE 802.11-08/0848r0 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 802.11n with 802.11i security, 802.11e QOS, and 802.11k Radio management for Traffic balancing –I want to seamlessly move from my 802.11 wireless LAN 5G to the 802.11 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

6 doc.: IEEE 802.11-08/0848r0 Submission The 802.11 alphabet soup 802.11d (approved 2001) – International support (Roaming, country to country, also includes 802.11c), Widely deployed. 802.1h (approved 2003) – Spectrum managed 5GHz, DFS (Dynamic Frequency Selection), TPC (Transmit Power Control) Widely Deployed 802.11i (approved 2004) – Enhanced Security baseline for every product (WPA2 @ WFA) 802.11e (approved 2005) – Quality of Service, parts of it widely deployed 802.11k (approved 2008) – Radio measurements helpful for load balancing, network maintenance etc.. (To be deployed at 2009) 802.11w (Ongoing) – Security for management frames (expected to be deployed in 2009) January 2008 Gal Basson (Wilocity)Slide 6

7 doc.: IEEE 802.11-08/0848r0 Submission The 802.11 alphabet soup 802.11s (Ongoing) – mesh networking 802.11r (Almost published) – Fast roaming 802.11u (Work in progress) – Advertising under 802 before association 802.11v (Work in progress) - Network management 802.11z (Work in Progress) – DLS (Direct Link Setup) 802.11aa (work in Progress) - Video Transport Stream More: –802.11j – Japan support –802.11y- 3.65-3.7G spectrum support January 2008 Gal Basson (Wilocity)Slide 7

8 doc.: IEEE 802.11-08/0848r0 Submission The 802.11 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 2012. Wi-Fi Alliance certification to 802.11a/b/g/n ensures interoperability and has enabled wide market adoption January 2008 Gal Basson (Wilocity)Slide 8

9 doc.: IEEE 802.11-08/0848r0 Submission Backup January 2008 Gal Basson (Wilocity)Slide 9

10 doc.: IEEE 802.11-08/0848r0 Submission Wi-Fi Alliance January 2008 Gal Basson (Wilocity)Slide 10 The Wi-Fi Alliance is a “Non-profit organization with the goal of driving the adoption of a single worldwide-accepted standard for high-speed wireless local area networking” “The Wi-Fi Alliance develops rigorous tests and conducts Wi-Fi certification of wireless devices that implement the universal IEEE 802.11 specifications” Over 300 companies members (regular, Affiliate, adopter) Company logos represent the Board of Directors

11 doc.: IEEE 802.11-08/0848r0 Submission Wi-Fi Alliance activities Address the market needs for specification –Slow Specification process (WPA for security) Test plans for the different 802.11 amendments Plug fests Interoperability events Interoperability lab January 2008 Gal Basson (Wilocity)Slide 11

12 doc.: IEEE 802.11-08/0848r0 Submission LAN ecosystem is much more than a PHY Can we implement Wireless LAN over 802.15.3c ? –Sure we can, but at what cost? One Example: –I have a client running 802.11n with 802.11i security, 802.11e QOS, and 802.11k Radio management for Traffic balancing –I want to seamlessly move from my 802.11 wireless LAN to the 802.15 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 802.15.3c, it seems to be a negative ROI, given these features already exist in 802.11 January 2008 Gal Basson (Wilocity)Slide 12
