What Is A Signal Booster

A cell phone repeater (also known as cellular repeater, amplifier, or cell signal booster) is a device used to improve cell phone reception in an indoor outdoor environment. A cell phone repeater is typically made up of three primary components:

• An outside antenna - also called a "reception" antenna
• A signal amplifier
• One or more rebroadcast antennas

It's a solution that takes an existing outside cell signal, amplifies it, and then broadcasts the boosted signal to an area inside of a building or vehicle that needs better signal. 

What Signal Booster Does Not Do

A cell phone signal booster requires an existing outside cell signal to boost. It cannot create it's own cellular signal, so if there is not an existing outside cell signal available, then a cell phone signal booster will not work.

Will it work for my carrier?

It's important to note that the frequency bands used for mobile communication can vary by country and even by mobile service provider within a country. It's best to confirm which frequency bands are used in your area.

This booster works for Band 28. Provided that your mobile phone operates on the same frequency as the amplifier, it will effectively function.

You could contact your mobile service provider or utilize your phone to confirm the frequency. 

Here's how to check frequency bands with cell phone.
