Mobile Phone Repeaters
What is a Mobile Phone Repeater?
A mobile phone repeaters main function is to improve the signal inside a building. It does this by grabbing the outdoor signal, boosting it up and rebroadcasting indoors. A mobile repeater has two ports, one for connecting to an outside antenna and the other for connecting to an indoor antenna.
The outdoor antenna is usually mounted on the roof and pointed towards the tower to get the best possible input signal. The indoor antenna is located inside the building in a position where maximum coverage is achieved.
Mobile Boosters include a amplifier module capable of providing a typical gain of 40-100dB. For a repeater to work, there must be signal available at the antenna to amplify. If a mobile signal is not present the repeater will not work.
Mobile Phone Repeater can also be known as Cell Extenders, Cell Phone Repeaters or Bi-Directional Amplifiers (BDA).
