`
`•
`
`Background
`• Market expectations exist for continual significant increase in
`WLAN speed and performance and thus renewed product success
`• 802.11a represents a 1st generation solution for high data rate
`WLANs
`– Legacy behavior will limit attainable performance
`• Low power operation
`• Capacity / peak throughput / range
`• QoS
`Incremental enhancements to 802.11a/g will limit the capabilities
`improvement achieved, and may miss market requirements in the
`medium to long term
`– Will also result in market fragmentation
`• Only one option:
`– Make Significant improvements through introduction of new, scalable
`technologies

`
`Drivers
`
`• In order to ensure continuing WLAN market expansion
`and product life extension, the second generation
`standard needs to be carefully designed in terms of:
`– Optimized cost / power / capacity / performance envelope
`– Backward compatibility or coexistence with first generation
`systems
`– Support of new applications as they emerge over time

`
`HTSG Proposed Purpose
`To define PHY and Medium Access Control
`protocol that can be gracefully deployed in the 5
`GHz band and support:
`•100-200Mbps for raw peak user rate, together with
`higher effective cell throughput (70-140Mbps)
`• low bit rate applications (increased voice capacity)
`• flexible tradeoff between power, capacity and
`performance.

`HTSG Technical Avenues
`
`• OFDM with higher number of sub-carriers and higher order
`QAM
`• Space-time coding techniques
`– e.g. 2 x 2 MIMO
`• New channel coding techniques
`– e.g. low constraint length turbo-codes,
`• Hybrid ARQ
`– Incremental Redundancy (IR) and Chase Combining
`• MAC efficiency improvement
`– e.g. TDD/TDMA incl. backward compatibility
`– Reducing overhead in the MAC will only be part of the story

`
`Conclusion
`
`• Imperative that we make big strides in developing
`the 802.11 standard
`– Small incremental changes will have only limited
`improvements in capability
`– New technology can allow a paradigm shift in
`applications
