A repeater is a device that allows you to amplify a cellular signal. It is needed in places where the signal is too weak due to the distance from the base stations or due to a large number of interferences of both natural and artificial origin. The device is equally effective in receiving and transmitting a signal within its range.

The choice of a communication amplifier depends on what you will use it for – for cellular calls or for accessing the Internet. If you only need to improve mobile communication, a repeater of the GSM standard is suitable. To access the Internet, a device with 3G or 4G support is required. And if you are going to call and access the Internet, you will need a repeater using GSM, 3G and 4G standards.

Installing a repeater yourself is not difficult, but you need to follow a number of rules:

It is recommended to install the external antenna for signal reception as high as possible, ideally on the roof, where there will be a minimum of obstacles around it.
The distance between the external antenna and the antenna of the subscriber’s device should be at least 5 meters. A shorter distance will lead to self-excitation of the external antenna.
If you are outside the city, try to point the external antenna towards the nearest base station. If in the city, place it in such a way that the signal reception of all operators is uniform.
After all the cables are connected, be sure to check how the system works, test the reception level. It may be necessary to adjust the location of the antenna.
After full adjustment and testing, lock all items securely.

The number of users does not affect the quality of communication. The main thing is that it is in the coverage area of ​​the device. Any number of subscribers can use the connection at the same time.

This information can be found in the list of technical characteristics of the specific model. The maximum distance depends on the power of the device and the communication standard used. A standard cable is included with the repeater, it is best to use it when installing the system.

Different models operate in different ranges (from 800 to 2600 MHz). They are also designed to enhance different communication standards – 3G, 4G or GSM.
