How do cell signal boosters work?
Cell phone boosters work transparently and efficiently with the complexity running behind the scenes.
Cell phones are actually two-way radios hidden behind a modern user interface. Mobile phones communicate with cell towers by using radio frequency (RF) signals.
A cellular signal booster operates as follows:
- Faint signals that can't be detected by a phone are collected.
- The faint signals are amplified.
- Amplified signals are broadcasting to an interior space where they can be used by phones or other cellular devices.
- When a device transmits the signal back to the tower, the reverse process takes place.
Cell signal booster systems have three basic components connected to each other with coax cables.
- An outside antenna is mounted on the roof or an exterior wall and communicates with the cell tower.
- Signals are passed along coax cable to the booster unit which amplifies the signal. The amplified signal is passed along coax cable to the inside antenna.
- Inside antenna distributes the amplified signal to the interior space where it is used by any cellular device.
