Description
A cell phone repeater is an electronic device used in areas where cell phone reception in very low or spotty. The repeater system will pick up and boost a cell phone signal, making it easier to receive. It can also amplify outgoing cell phone transmissions. The repeater is completely wireless, and does not require a physical connection to a cell phone.
System Configuration
Cell phone repeater systems consist of an antenna that is more highly sensitive than that in your cell phone. The antenna is usually mounted on the roof and is connected by coax cable to a fuse, which protects the repeater system against damage from lightning. The fuse is connected to an amplifier, which in turn connects to an antenna within the building.
Incoming calls
When an incoming call is transmitted through the cell phone system, the antenna on the roof will pick it up, boost it, and send it through the coax cable it to the amplifier. The amplifier will then boost the signal significantly more, then send it to the internal antenna within the building. The internal antenna covers a specific area and will broadcast the call signal to your cell phone. The signal will be several more time as strong as the original signal.
Outgoing Calls
For outgoing calls, the process is reversed, with the internal antenna picking up your call signal, transmitting it to the amplifier, then out to the outside antenna for broadcast.
