that you can use for long-distance point to point links is the Ubiquiti
Airfibre 5X. This device is engineered to give you adequate throughput even when
your link covers a distance of about 200km. If you have your radios properly
configured and aligned, you are guaranteed of nothing less than 100Mbps on a
link of about 50km. That said, while deploying the Ubiquiti Airfibre 5X, you must
not forget that it uses the unlicensed 5GHz frequencies and as such, is
susceptible to interference. With this in mind, it is highly unlikely that you
get up to the 500Mbps over 200km as stated by Ubiquiti, but with good setup and
optimization, you can get enough throughput to take care of your bandwidth needs. Let’s see how it is done below:
Ubiquiti Airfibre 5X is setup in a master-slave settings, similar to the
AP-Station that we are all used to. The transmitting device is configured as the Master while the receiving is the Slave. To connect to the master radio, do
the followings on your computer:
Assign the IP 192.168.1.1
Connect a cable from the data port of the radio adapter to the LAN port of your
Confirm connection to the radio by pinging it from the command prompt.
Open a web browser and enter the IP 192.168.1.20
The default username is ubnt while password is ubnt
successful login, do the following:
Set wireless mode to Master
Set link name
Click on change and select country of residence
Channel width can be set to 40MHz
Set Max modulation mode to 10x
On frequency setting, choose frequencies from the list of allowed frequencies
for your chosen country.
Set wireless security to ASCII and enter password.
Change the IP on the radio to something else
Set the wireless mode to Slave
Set link name to same as Master
Change country to same as master
Set channel width to same as master
Set frequency to same as master
Set max modulation mode to same as master
Set Wireless Security to same as master
Change IP. IP must be on the same subnet with the one set on the master.
connected, you will get connection status as shown in the image below.
