Background

The High Efficiency WLAN Study Group (HEW SG) is a study group within IEEE 802.11 working group that will consider the improvement of spectrum efficiency to enhance the system throughput/area in high density scenarios of APs and/or STAs.

 

The study group was created based on the following straw poll and motion:

<Straw Poll>

Do you support starting a new study group called �ghigh efficiency WLAN�h to enhance 802.11 PHY and MAC in 2.4 and 5GHz with a focus on:

l  Improving spectrum efficiency and area throughput

l  Improving real world performance in indoor and outdoor deployments

Ø  in the presence of interfering sources, dense heterogeneous networks

Ø  in moderate to heavy user loaded APs
