Radio networking

Is it that you are trying to connect to remote offices with a radio connection? For a radio connection between two antennas line of sight between the two is very important. The first job is to make sure that the link is a good one. The rest is just hooking up the modem to the router and then to your wired network.
Good luck.

This is the term you probably mean. All present wireless technologies require clear line of sight between the sending and receiving antenna. With any distance beyond about 12 km, the curvature of the earth becomes a significant factor. Anything between the sending and receiving antennas (buildings, vegetation, terrain) may degrade the signal beyond useful strength or even prevent reception. With the distance you are talking you will need either tall antenna masts(which will add to cost) or intermediate repeaters (which will significatly add to cost. Without in-depth knowledge of radio communications, radio-wave propagation and antenna theory and design, your best bet is to leave a project like this to a vendor that specializes in thistype of installation.

I have installed several wireless links using 2.4 and 5.7 license free bridges over a variety of distances up to 14 miles so far. The equipment specs out to 25 miles so this might be what you need. You can do a point-to-point or multi-point solution if needed.

How much would setting up a network with a relay in the middle? Just the hardware, that is?
