How car amplifier Boosters Work?

 

Signal Boosters improve cell phone coverage by capturing the weak signals at certain frequency range and then amplifying the signals. Boosters do not process the signal, so they cannot distinguish signals and noises. They just simply amplify everything in their operation frequency range.

 

Even though the concept is simple, it is still a little challenge to make a good booster. The cell phone signals are tiny electric waves at very high frequencies. A very low level of noises, which are introduced during the boosting process, can significantly distort the original signals or interfere with the signals at other frequency spectrum. It is also hard to boost signals evenly on the frequency band. Any time lags caused by the process can make the signal useless as well.

 

Key Parameters that you should Care about

 

Frequency Band

 

determines which frequency of signals will be amplified. In North America, there are currently two frequency bands than wireless phone services operated within. One is CELL 824 - 894 MHz, the other is PCS 1850-1990 MHz.

 

System gain

 

measures how powerful the car amplifier  Booster system can amplify the electric waves at its operation frequency. It is car amplifier booster gain plus antenna gain minus cable loss. So, with better antennas and cables, you can get a little more gains. Total Antenna gains are usually under 8dB, the loss for 50ft long cable is around -4dB.

 

Noise

 

means how badly the system creates noises. If a booster introduces too much noise, it would actually amplify noises instead of signals. The lower the number, the better the booster can pick up a weak signal.

 

Of cause there are many other specs that measure many other different aspects of the system. However, for end users, System gain and Noise are two main parameters that determine the quality of a booster.
