Mobile/ Cellular Signal Boosters Explained

The main function of the cellular mobile signal booster is to amplify the signals to and from a cellular tower, improving mobile phone and mobile data performance. Signal Boosters solve the challenge by retransmitting a cellular signal from a donor tower into a targeted area resulting in fewer dropped calls and reliable data transfers. In automotive applications, a signal booster can ensure a reliable cellular experience whilst on the move or camped up in the harshest of areas.

Cel-Fi signal boosters are designed to operate with Telstra, Vodafone, and Optus to improve cellular use in places with weak reception. The strength of the cellular phone signal is usually affected by diverse obstructions, like trees, construction materials in buildings and hills as well as distance. This is where the Cel-Fi signal booster system is designed to operate.

Firstly, the cellular network signal is captured by the outside antenna. It is then amplified by the Cel-Fi signal booster and then rebroadcast across the building or car through the inside antenna. The result is boosted cellular phone reception that culminates in more bars on your phone even in remote locations. You can then enjoy clearer calls that will not drop out, faster internet browsing, and rapid data downloads and uploads. This is how the Cel-Fi signal booster works in your car or house.

This is how all signal boosters work on every technology platform including GSM, CDMA, TDMA, EVDO, UMTS, HSPA+, and the latest LTE. A cellular booster will not work if there is no signal to start with. Cel-Fi signal boosters require at least some signal to amplify.
