  The Booster is designed to boost signal strength and ensure reliable coverage for cell phones, PDAs and laptop air cards, 

no more dropped calls or poor cell phone reception!


Works with AT&T, Verizon,Alltel, Cellular one, ROGER, BELL and any wireless operator in the frequency range of 824-894 MHz, (850MHZ) CDMA, GSM System.

You will need a different PowSignal products for iDEN(Nextel), or some 1900 MHz services.

Please visit Enter your zip code and locate your service provider to find the coverage frequency in your service area. It is important that you find out the coverage frequency because this product ONLY SUPPORTS 850 MHz. When you check, if both 850 MHz and 1900 MHz are listed, our product will work for you. IF ONLY 1900 MHz IS LISTED, DO NOT BUY THIS PRODUCT.In such a case, please visit our eBay store for other models.

We carry Dual Band Booster please ask a quotation.

We guarantee a much stronger signal than Wi-Ex products.

How All Signal Boosters Work:

Signal Boosters improve cell phone coverage by capturing the weak signals at a 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, making a good booster is still a challenge. The cell phone signals are tiny electric waves at very high frequencies.  A very low level of noise, which is 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. 


Key points to consider before purchasing any booster:

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


means how badly the system creates noise. If a booster introduces too much noise, it could actually amplify noise instead of signal.  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 amount of noise are two main parameters that determine the quality of a booster.


Included in the Package:

  • PowSignal UNIT - The heart of the PowerSignal Booster system is a revolutionary signal enhancer that blends with most home and office environments.
