It varies. The range of a repeater is dependent on the power output of a repeater. In general, a standard repeater system can improve the cellular reception in an area up to 2,500 sq. ft.; enough to cover a home or small office. (This corresponds to a power output of between 5 and 10 dBm). For larger buildings, a repeater with a greater power output is more appropriate. We recommend the following approximate guidelines:
For use in home/small office or any other area up to 2,500 sq. ft.. |
 |
5-10 dBm |
For use in a large office/building or any other area up to 25,000 sq. ft.. |
|
> 10 dBm |
For use in a car or other vehicle |
|
In car model |
The coverage areas quoted are for optimal conditions. The exact coverage area a cellular repeater will yield is dependent on a number of different factors, such as the construction materials of the building the repeater is installed in, and the outside signal strength where the repeater's antenna is to be installed.
In order to maximise the coverage area, it is beneficial to have at least two bars of signal somewhere outside or inside the building, where the antenna will be installed. Also, you should take care to install the actual repeater unit as centrally as possible and away from metallic obstructions. Even if these conditions cannot be met, cellular repeaters will, in general, offer significant improvements in cellular reception
