Background

On January 2015 the Next Generation Positioning Study Group (NGP SG) a study group within the IEEE 802.11 working group had started its activity to address the needs of a Station to identify its absolute and relative position to another station or stations it’s either associated or unassociated with.

The NGP SG has successfully developed a PAR and CSD documents and project 802.11az initiated its work on Sep. 2015.

Goals

To defines modifications to both the IEEE 802.11 medium access control layer (MAC) and physical layers (PHY) of High Throughput (HT), Very High Throughput (VHT), Directional Multi Gigabit (DMG) and PHYs under concurrent development (e.g. High Efficiency WLAN (HEW), Next Generation 60GHz (NG60)) that enables determination of absolute and relative position with better accuracy with respect to the Fine Timing Measurement (FTM) protocol executing on the same PHY-type, while reducing existing wireless medium use and power consumption and is scalable to dense deployments.
