A cell phone signal booster is a system which takes a cell phone signal from one area where the signal is good, and repeats (or amplifies) it to an area where the signal is not good or nonexistent. A cell phone repeater has three main parts, an outside antenna that receives the initial signal, an amplifier that boosts the signal, and an inside antenna that broadcasts the boosted signal to the inside are that needs it. All three components are connected together with high quality cable. The systems usually use an external, directional antenna to collect the best cellular signal, which is then transmitted using coaxial cable to a signal amplifier unit, and then transmitted using more coaxial cable to an interior antenna which retransmits it to the users.
A cell phone repeater is able to bring a weak signal inside and amplify it significantly, but it does require a stable signal in the area where the external antenna is placed in order to work. Ideally, this is a strong signal that it can repeat, but even a weak signal can be adequately amplified when combined with a strong amplifier. A cell phone repeater will not work for areas which have no signal or have a signal which is unstable and repeatedly cuts out. If you are able to place the external antenna in a location which has signal, then a cell phone repeater should work for you. There are different types of cell phone repeaters which vary in strength and can be configured with different types of antennas in order to solve your situation.
The more advanced models often also allow multiple cell phones to use the same repeater at the same time, so are suitable for commercial as well as home use. Some political jurisdictions require these systems in all new large buildings to support emergency use (i.e. police, fire and paramedic).
