How do cell phone repeaters work?

The outdoor donor antenna is connected via coaxial cable to an amplifier unit which amplifies the signal, and retransmits it locally via one or more indoor antennas, providing improved signal strength inside the building. Smaller cell phone repeaters are also used inside vehicles, boats, and recreational vehicles to improve reception for users.

What are the different types of cell phone repeaters?

The two types of repeaters are passive and active. Passive repeaters have no amplifier and pass information from one antenna to another via cable. Active receivers also use antennas and cables; however, an amplifier boosts the strength of the power output to your devices. Both types of repeaters boost your phones.

How much noise does a cellular repeater need?

For most amplifiers, this is between 6 dB and 8 dB. In order for a cellular repeater to operate correctly, the signal-to-noise ratio (SNR) of the donor signal must be greater than the noise figure of the amplifier. Without adequate signal at the donor antenna location, no improved signal will be experienced by users.
