IEEE unveils two more groups for wi-fi standard


IEEE and the IEEE Standards Association have formed new study and topic interest groups focusing on the 802.11 communications specification.

The groups IEEE 802.11 Extremely High Throughput Study Group and the IEEE 802.11 Real-Time Applications Topic Interest Group aim to enhance WI-FI functionalities and adoption, respectively.

The Extremely High Throughput Study Group will initiate discussion on the new IEEE 802.11 features for bands between 1 and 7.125 GHz.

The aim is to amend the IEEE 802.11 to support demanding applications such as video over wireless local area networks (WLANs), augmented reality (AR) and virtual reality (VR).

Michael Montemurro, chair of the IEEE 802.11 Extremely High Throughput Study Group, said: “We are seeking stakeholders throughout the IEEE 802.11 ecosystem to share their experiences with the standard and needs for features such as more spatial streams, higher bandwidth, multi-AP (access point) techniques and multiband switching, aggregation and operation.

“We envision a rapidly paced effort over the next six to nine months, which we hope will bring into clear definition the most important requirements to be addressed in accelerated development of a possible future amendment to the IEEE 802.11 base standard.”

Problem areas and piloting solutions

The IEEE 802.11 Real-Time Applications Topic Interest Group is quantifying performance lags and stability issues that have been observed with real-time applications such as mobile and multiplayer games, robotics and industrial automation.

The group is working to document usage models and requirements metrics for real-time applications.

Said Allan Jones, chair of the Group: “Immersive gaming, for example, is very latency sensitive and requires a quick turnaround on packets for users to enjoy a high-quality experience. Jitter, packet loss and what’s going on throughout the network can have a large impact on these real-time applications, which may have only moderate bandwidth requirements but have very low tolerance for latency.

“What we’re trying to do in our group is define more specifically what these requirements are for this particular category of applications, toward the goal of informing ongoing IEEE 802.11 innovation.”
