9. 1. Broad Market Potential
January 2001
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. January 2001
2. Compatibility
Compatibility with IEEE a will result from the use of the MAC (including planned enhancements)
VK Jones, Ph.D, Woodside Networks.

11. January 2001
3. Distinct Identity
a: Substantially different from other 802 projects
Proposed speeds significantly extend a 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

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 a with 2x mode
VK Jones, Ph.D, Woodside Networks.

13. 5. Economic Feasibility - Requirements
January 2001
5. Economic Feasibility - Requirements
Semiconductor process technology now being used to implement is adequate for higher rates
Products that include the data rate improvements should be made available at cost points relatively close to a cost points
Installation cost of higher rate devices should approximate current a and b. installation cost points
VK Jones, Ph.D, Woodside Networks.

14. (6) Interference Contribution to Network- Requirements
January 2001
(6) Interference Contribution to Network- Requirements
Target technology should consider effects on mean signal-to-interference ratio across a network of a and a HR radios.
Target technology should address international regulatory issues governing the use of the band
Target technology should address potential impacts on other non users of the band
VK Jones, Ph.D, Woodside Networks.

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 framework
Cost, complexity, power, and range criteria are impacted differently depending on which approach is chosen
IEEE working group should start a ‘Higher Rate a Study group’ (HRaSG)
