Also called a GSM repeater, the GSM amplifier repeats a signal identically. The goal is to get a high signal to send it to where you need it.
First, the system captures the signal where it is and then sends it to the device via a cable. The repeater will then amplify it and send it to an antenna near your mobile phone, where you want to get a good network.
This makes it possible, for example, to obtain a good network in a place which initially does not allow making calls with a smartphone.
The GSM amplifier consists of several parts:
- An outdoor antenna, responsible for receiving the signal from your operator's relay antenna.
- A GSM coacial cable connected to the GSM repeater responsible for amplifying the signal and sending it to the antenna installed inside.
- The indoor antenna, located near the place where you are calling. Several models exist for your interior installation.
