 To validate, run `which iw` to see where is current path for `iw` and run `iw --version` to see if it is `iw version 4.14`.

+### AP side
+Simply enable HostAPd.

+First create a file `config_entry` contains the following entry:
+```
+<mac_address> bw=20 cf=2462 retries=5 asap
+```
+where `bw` is the bandwidth, `cf` is the center frequency of AP's channel.
+
+Then request FTM measurement via
+```
+sudo iw <wlan_interface> measurement ftm_request config_entry
+```
+### Result example
+You should see something like the following:
+```
+Success to put for target 34:f6:4b:5e:69:1f.
+phy #0: FTM result! Status: 0 
+Target: 34:f6:4b:5e:69:1f, status: 0, rtt: -33429 psec, distance: -501 cm
+```
+If you see anything other than `status: 0`, it means it is not succeeded.
