How to find the Carrier's Bands infromation (Frequency) that your cell phone used

The repeater will only work properly if the frequency of the repeater is the same as the frequency of the carrier's base station. Before purchasing a repeater, you should first specify the carrier frequency of the place where you need to boost the signal.

Basic Physics for Wireless Communications - Electromagnetic Wave

With the development of science and technology, radio wave applications have penetrated into every aspect of our lives!
Radio/TV; mobile phone communication, Wi-fi Bluetooth, infrared remote sensing.
To understand wireless transmission, first we need to understand the basic physical knowledge: electromagnetic waves.
