Dear EC, In preparation for the March 802 Plenary meeting I am submitting for your consideration a PAR and CSD from 802.11. These documents were generated and approved within the HEW (High Efficiency WLAN) study group and subsequently approved by the WG in our closing 802.11 plenary today. A portion of the PAR is reproduced below to provide a brief explanation of our goals. 5.2.b. Scope of the project: This amendment defines standardized modifications to both the IEEE 802.11 physical layers (PHY) and the IEEE 802.11 Medium Access Control layer (MAC) that enable at least one mode of operation capable of supporting at least four times improvement in the average throughput per station (measured at the MAC data service access point) in a dense deployment scenario, while maintaining or improving the power efficiency per station. 5.5 Need for the Project: Wireless LAN (WLAN) devices are currently being deployed in diverse environments. These environments are characterized by the existence of many access points and non-AP stations in geographically limited areas. Increased interference from neighboring devices gives rise to performance degradation. Additionally WLAN devices are increasingly required to support a variety of applications such as video, cloud access, and offloading. In particular video traffic is expected to be the dominant type of traffic in many high efficiency WLAN ( deployments. With the real-time requirements of some of these applications, WLAN users demand improved performance in delivering their applications, including improved power consumption for battery-operated devices. Unlike previous amendments where the focus was on improving aggregate throughput, this amendment focuses on improving metrics that reflect user experience, such as average per station throughput, the 5th percentile of per station throughput, and area throughput. Improvements will be made to support environments such as wireless corporate office, outdoor hotspot, dense residential apartments, and stadiums.
