Do Cell Phone Signal Boosters Work?

Yes, our cell phone signal boosters work. As long as there's some signal outside, they can multiply that signal up to 32 times to provide strong cellular reception inside homes, offices, and vehicles.

Unfortunately, there are many cellular phone signal boosters available on the market that simply don't work as advertised. All cell phone boosters we supply do however work and will amplify weak signals by taking signals received outside and bringing these inside and amplifying them. It should also be noted that any cell signal booster will only work if there's in fact enough signal outside to place a call. Without any signal outdoors, no cellphone booster will be able to work.

Why does signal strength reduce?

Slow data rates and dropped calls are normally caused by the distance from a cell tower, man-made obstructions and terrain features.

How does cellular booster increase signal strength?

There's logic and science behind how cell signal amplification occurs. Using a high gain antenna or combining an antenna and a bi-directional signal booster system will boost cellular signals for both data and voice. We offer multiple solutions to stay connected.

Ensuring reliable cellular communications consists of two parts:

  1. Part 1 is receiving a strong signal. High gain antennas collect distant or weak cellular signals and send them to a signal booster. The booster amplifies those signals and rebroadcasts them inside for use by cellular phones and other devices.
  2. The second part of the solution is to transmit a strong signal back to the cell tower. Cell phones have limited transmission power, making this the weakest part of a mobile communications link. A much stronger signal can be broadcast back to the cell tower at a greater distance when using a bidirectional signal booster.

All our signal boosters are FCC certified. We offer a wide range of powerful vehicle and building signal boosters for all carriers as well as high-gain antennas with multiple mounting options.
