Background

The publication of IEEE 802.11-2016 Fine Timing Measurement (FTM) is the original accurate positioning (2nd Generation range) moving from Received Signal Strength Indication (RSSI) to an accurate Time of Flight (ToF) based range measurement.

IEEE 802.11az-2022 saw major improvements to FTM allowing <1m accuracy levels:

·       Privacy and security via MAC level and PHY Symbol level measurement protection

·       Native IEEE 802.11 MIMO support providing spatial diversity, enhanced link budget via use of 802.11ax based waveforms

·       Shorter measurement time for improved power, QoS and spectrum efficiency.

and is referred to as 3rd generation 802.11 based positioning.

The introduction of 320MHz channelization as part of IEEE 802.11be, provided additional opportunity to improve accurate positioning of the IEEE 802.11based solutions.

Goals

 320 MHz Positioning is a new Task Group within the IEEE 802.11 working group that will enhance the IEEE 802.11 FTM positioning protocols with the IEEE 802.11be derived 320MHz waveforms. This increase from the IEEE 802.11az maximum of 160MHz will provide a substantial performance gain in accuracy levels.

Coupled with the IEEE 802.11 native MIMO support and superior link budget, this enhancement will bring IEEE 802.11 technology to the very cutting edge of accuracy, security, and reliability of current and observed future connectivity-based positioning.
