What is a "Mobile Repeater"? The Most Authoritative Explanation.
What is a cellular repeater?
A cellular repeater(also known as cell phone signal boosteror cell phone signal amplifier) is a type of bi-directional amplifierused to improve cell phonereception.What is an analog repeater?
Analog repeater. This type is used in channels that transmit data in the form of an analog signal in which the voltage or current is proportional to the amplitude of the signal, as in an audio signal. They are also used in trunklines that transmit multiple signals using frequency division multiplexing (FDM).How does a low-gain mobile repeater work?
The idea is that your mobile phones and other cellular devices can connect to the indoor antenna and get coverage that’s at least as good as if they were located outside. A low-gain mobile repeater works on a similar principle, but is designed to improve the signal inside a moving vehicle.What if there is no signal to amplify a cell phone repeater?
If there is no signal to amplify, the cell phone repeater system will be nothing but an expensive trinket. The weaker the incoming signal, the more difficult it is to amplify, and the more systems you will need to adequately cover a large space. The additional noise added by an amplifier is called the “noise figure.”
