FTM Protocol Overview
This page introduces an open platform for experimenting with WiFi fine time measurements (FTM). Our FTM tool is based on Intel Dual Band Wireless-AC 8260 cards, and open source linux driver.
The IEEE 802.11-2016 now includes a FTM protocol for WiFi ranging, and several WiFi chipsets offer hardware support albeit without fully functional open software. Our tool reports the round trip time and the corresponding distance between a station and the intended access point.
