The link between APs in wireless mesh design is a bridge. That means, there is a root bridge and you should issue the command from the root access point. The command is self-explanatory with 'client' in it. You can use iperf but it only shows the ...
Beamwidth is determined by only 3dB off of the center, so it is not like losing signal outside the 6 degree range.Reading RSSI is the way, but the reading is very slow, so you have to give few seconds to allow the AP to recalculate the RSSI each time...
This is more of a Physics question.You can try using 5GHz antenna on a 2.4GHz radio, however, the SWR must be very high and not much RF will be radiated from the antenna. Most RF energy stays in the transmission line as a standing wave and consumed ...
