How many sq. ft. area can indoor cell signal booster cover?
The square footage size of indoor coverage area of a cell phone signal booster is determined by two factors:
- The cellular booster system's gain as stated in its specifications.
- The cell signal strength outside before being boosted inside.
The coverage area provided by any booster varies greatly with the strength of the tower signal received, with a bigger area being covered by a stronger signal.
This is the reason why outside antennas are placed in a location, and pointing in the direction, that allows it to receive the strongest signal.
This is a very simplistic response to the question posted in the title. If you wish to read a more detailed and in-depth article with a video illustration, please read, "how to calculate cell booster coverage area".
