Determining coverage areas for Base Stations and Relays As we said before, it is almost impossible to predict the effective RF
communications range in a given environment. The typical area of coverage
is a 1000 - 3000 ft. radius.
After a Site Test, if you have determined that you will need to add Relays to
cover the area you want to operate in, you will need to determine where to
place your Relay in relation to your Base Station. To effectively cover an
area, there must be overlap between the area covered by the Base Station
and the area covered by the Relay. The example below shows what can
happen with no area overlap:
As you can see, the only area adequately covered is in a path where the two
circles touch. The “dead space” is completely without coverage. Alternatively,
locating the Base Station and Relay as shown below results in better coverage:
