Cell phone repeaters are an emerging technology of bi-directional cellular amplifiers. If you are suffering from weak cellular signal, then a cellular repeater system can help you by improving the cellular reception that you experience. It does this in two ways:
1. A cellular repeater system will include an antenna which sits outside your building, where the cellular signal is stronger, and feeds this strong signal into your building through a low loss cable.
2. The cellular repeater system actively boosts this signal through the bidirectional amplifier because both incoming ''and'' outgoing signals are boosted.
After a rocky start, cellular repeater technology has much improved and now there are a variety of repeaters which are licensed by the FCC, the body which monitors the communications industry. Be sure to look for this endorsement when buying a repeater, but rest assured that all cellular repeaters from the established manufacturers such as Wilson Electronics, Clear Voice and WiVehicle versions, Large building versions and standard home/small office versions.
