P802.11 – High Efficiency WLAN STUDY GROUP - MEETING UPDATE
Status
of IEEE 802.11 HEW Study Group
High
Efficiency WLAN (HEW)
Osama Aboul-Magd (Huawei
Technologies), Chair
Yasuhiko Inoue (NTT), Recording
Secretary
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 “high efficiency WLAN” 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
<Motion>
Request approval by IEEE 802 LMSC to form an
802.11 Study Group to consider High-efficiency WLAN [as described in doc
11-13-0339r2] with the intent of creating a PAR and five criteria.
HEW study group had seven sessions during the week.
