This page is shows how to configure wireless links between BSC and BTS. Here we are using Ubiquity airGrid links, though most Ubiquity links will be similar.

The equipment

Ubiquity Airgrid[1] | air OS Manual [2]

Connect to the airGrid

Connect the airGrid to the POE port on the power supply via ethernet cable and the work machine to the LAN port.

Plug in the power supply to boot up the antenna.

In your browser connect to the interface via https://192.168.1.20.

Username and password are both : ubnt

Country: Mexico

Language: English

Under Wireless tab:

Wireless Mode: Station (for tower/BTS) , Access Point (for BSC)

WDS (Transparent Bridge Mode): Check for Enable

SSID: RHIZO_INSTALLNAME (eg: RHIZO_ALOTEPEC). Set SSID to be same for both links!

Security: WPA2-AES WPA Authentication: PSK WPA Preshared Key: same key between antennas

Under Network Tab

Network mode: Bridge

Management Network Settings:

Management IP Address: Static

IP Address:172.16.0.250 ( within 172.16.0.0/24 with exception of 172.16.0.1, 172.16.0.11 (BTS) and 172.16.0.12 (BTS), generally between 172.16.0.250 and 172.16.0.255)

Netmask: 255.255.255.0

Gateway IP: 172.16.0.1

After clicking change and then Apply, change DNS settings on your work machine to an unassigned static IP in the 172.16.0.0 range (eg: 172.16.0.34) log back in via IP address to the assigned airGrid: eg: 172.16.0.250

Under System Tab

Change password by clicking little key to the right of //Administrator Username//.

Change and Apply everything by clicking the corresponding buttons!

Maintenance from a distance

One can ssh into the airgrid from the connected BSC or otherwise from the network

(eg: ssh ubnt@172.16.0.250)

vi /tmp/system.cfg

edit the config

then "save && reboot"

Example config file

This for the Cajonos tower link (/tmp/system.cfg):
