A mobile phone repeater operates within apparatus or spectrum licensed radio-frequency bands.
Gain is simply the measure of a boosterâs or antennaâs signal output relative to its signal input. Gain is usually expressed in decibels (dB), a standard unit of measure for signal strength. If a booster provides a maximum 50 dB gain, then the boosted signal coming out of the unit is up to 50 dB stronger than the unboosted signal that went into the unit. In a practical terms, gain represents the relative level of signal boost that a booster and/or antenna is capable of providing.
