  1. Interest for HDR extension to 802.11a VK Jones, Rolf DeVegt Woodside Networks John Terry Nokia Research VK Jones, Ph.D, Woodside Networks.

  2. Topics • Introduction and Objectives • Market Needs • Target Solution Requirements – 6 Criteria • Conclusion and Proposed Next Steps VK Jones, Ph.D, Woodside Networks.

  3. Objectives of the Presentation • Convey the market needs for higher data rate 802.11 technology (>100Mbps) • Indicate that the 6 Criteria for an IEEE 802 PAR can be met • Make the case for the creation of a Higher Data Rate 802.11a Study Group (HRaSG) VK Jones, Ph.D, Woodside Networks.

  4. Four Distinct Market Drivers: Increasing Data rates in Wireline Ethernet More data rate Intensive Applications • 100 Mbps ->1 Gbps • Multimedia conferencing • MPEG video streaming • Consumer applications • Network Storage / file transfer Need for Higher Data Rate Wireless LAN Standard Need for Higher Capacity WLAN Networks Non-standard 100Mbps+ products entering the market • Hotspots / Service Providers • Wireless Back Haul • Increasing # of users per AP VK Jones, Ph.D, Woodside Networks.

  5. Timing is Right for Further Innovation Max. Data Rate Mbps 802.11a HDR 802.11 a + g 802.11 b 802.11 Time -> VK Jones, Ph.D, Woodside Networks.

  6. Solution Requirements • Worldwide Acceptance • Meets the 6 Criteria1. Broad Market Potential2. Compatibility3. Distinct Identity4. Technical Feasibility5. Economic Feasibility 6. Addresses Interference Issues VK Jones, Ph.D, Woodside Networks.

  7. Solution Requirements: Worldwide Acceptance • Compatibility with 802.11a PHY • Compatibility with 802.11 & 802.11e MAC • Compatibility with 802.11h DFS/TPC • Coordinated with ETSI BRAN VK Jones, Ph.D, Woodside Networks.

  8. 802.11 Five Criteria • Broad Market Potential • Compatibility • Distinct Identity • Technical Feasibility • Economic Feasibility • Interference Considerations VK Jones, Ph.D, Woodside Networks.

  9. 1. Broad Market Potential • Broad range of applicability: • Support high data-rate applications • Increase capacity of WLAN Networks • Enable wire-line to wireless migration / substitution • Multiple Vendors, multiple users • Balanced costs VK Jones, Ph.D, Woodside Networks.

  10. 2. Compatibility • Compatibility with IEEE 802.11a will result from the use of the 802.11 MAC (including planned enhancements) VK Jones, Ph.D, Woodside Networks.

  11. 3. Distinct Identity a: Substantially different from other 802 projects • Proposed speeds significantly extend 802.11a data rates (100Mbps+) b: One unique solution per problem- The project should define only one additional 5 GHz PHY rate extension VK Jones, Ph.D, Woodside Networks.

  12. 4. Technical Feasibility Potential Approaches to Study: • Modulation and Coding Enhancements • Spatial Diversity Techniques • Spatial Multiplexing 4. Double bandwidth solutions with underlying 11a waveforms • Example: Proxim Harmony 802.11a with 2x mode VK Jones, Ph.D, Woodside Networks.

  13. 5. Economic Feasibility - Requirements • Semiconductor process technology now being used to implement 802.11 is adequate for higher rates • Products that include the data rate improvements should be made available at cost points relatively close to 802.11a cost points • Installation cost of higher rate devices should approximate current 802.11a and b. installation cost points VK Jones, Ph.D, Woodside Networks.

  14. (6) Interference Contribution to Network- Requirements • Target technology should consider effects on mean signal-to-interference ratio across a network of 802.11a and 802.11a HR radios. • Target technology should address international regulatory issues governing the use of the band • Target technology should address potential impacts on other non-802.11 users of the band VK Jones, Ph.D, Woodside Networks.

  15. Conclusion • There is significant future demand for an 100+Mbps WLAN standard • Non-standard 100Mbps devices already in the market • Data rate intensive applications require more throughput • Need for higher capacity WLAN networks • Increased rates in wireline networks • 100Mbps is an achievable goal • Multiple approaches to achieving 100Mbps in the 802.11 framework • Cost, complexity, power, and range criteria are impacted differently depending on which approach is chosen • IEEE 802.11 working group should start a ‘Higher Rate 802.11a Study group’ (HRaSG) VK Jones, Ph.D, Woodside Networks.
