Allow everything on WLAN1 that has a signal above -87dBm (eg, signal between -86 and+120 dBm) , and allow even that signal to drop below -87 dBm for 30 sec.
The allow is authenticate (associate) and forwarding (connect to other clients). The allow-signal-out-of-range is needed because devices are in their hands, so the signal fluctuates, but I prefer not to drop them immediately.
To stop the weak signal connections on WLAN1 the next line is needed. For everything with signal between -87 and -120 dBm there is no authentication allowed.
The allow-signal-out-of range is short here (1 sec) because this is used for roaming clients that are sticky to their first AP, but they may come back very soon to this AP, and I prefer not to deny them longer than needed.
To build 30 km point-to-point wireless connection on speed 100 Mbit/s we used two Cambium ePMP 1000 and two 27 dBi parabolic MIMO antennas.
To create point-to-point wireless link we need to configure first antenna as Access Point and the second antenna as Station. First of all make sure there are no interference in front of the antennas:
Let’s configure access point, to log in to the configuration panel open in your web browser address: 192.168.0.1 (Access Point) or 192.168.0.2 (Station). By default enter login: admin and password: admin
We will configure our link based on this schema:
On Access Point select SSID, your country code, work frequency, channel width (20 or 40 mHz) and security password:
Also to achieve the best result select TDD wireless protocol.
On the other side on Station antenna select the same parameters, but in Radio Mode select Subscriber Module.
Don’t forget to change default administrator passwords on both antennas and change your own static or dynamic IP addresses.
On page Monitor->Wireless make sure that your Station connected to Access Point:
