Cellular signal amplifier for giving

If your dacha is away from the radio tower, you have to make considerable efforts to take or make a call or connect to the Internet. Most likely, you are already pretty worn out. Without cellular communication and a worldwide network in our age it is difficult to imagine at least one day, and at the dacha we live at times a week, a month, or even the entire summer season. So how to solve this problem? It's very simple - you need a signal amplifier for your cellular network.

How does the cell phone signal booster work for the phone?

This device is a device with 2 antennas (external and internal), an RF cable and a repeater. An amplifier is installed indoors, and only an external antenna is mounted to the roof or wall from the outside.

Repeater serves to ensure two-way communication. It converts the changeable and weak signal of the modem into a good and confident one. Thus, the signal amplifier provides the coverage area with a steady signal throughout the entire territory of your holiday home .

How to choose a cellular signal amplifier?

GSM-signal amplifier of cellular communication or 3-G antenna? What to choose? The repeater (or repeater) GSM is designed to improve the reception quality of the cellular signal. Selecting the optimal model from the large number of available in the modern market is necessary, based on their own needs and the conditions of its planned operation.

First you need to determine the standard of cellular communication. Choose what services you need - mobile Internet, voice calls. If you need to improve the quality of the connection, then you need a GSM repeater, but if you want to increase the speed of the Internet, then you can not do without a more powerful 3-G antenna.

You also need to consider the compliance and maintenance of the repeater operator's work. So, for subscribers of the Tele2 network, the repeater is needed with the support of the GSM-1800 standard.

If you need to solve two problems at once, you need a dual-band GSM / 3-G repeater.

Which cellular signal amplifier is better?

Before buying and installing an amplifier, you need to measure the signal of the cellular network with several different mobile devices in order to take into account the likely differences in the sensitivity of the antennas of the phones. This will allow you to more accurately choose the amplification factor of the repeater. Follow this pattern: the worse the signal, the more powerful the repeater is, that is, it must have a large gain factor.

To determine the required CU (gain), you need to make measurements inside and outside the house. If in the house you see 1-2 divisions, and on the street - a full scale, you need an amplifier with a KU of 65 dB or more. Well, and even if you see on the street that the signal is weak, then the amplifier KU should not be less than 75-85 dB.

There are models of amplifiers with a CU of less than 60 dB. They are not recommended for use in any of the cases, as they do not provide a normal result and are not useful devices.

Also, when buying a cellular signal amplifier, you need to know the area of ​​your home in order to determine the power of the repeater. The larger the area, the greater its power should be.

A standard amplifier of 100 mW is able to amplify the signal in the territory up to 200 square meters, but repeaters with a power of 300 mW or more are recommended to use in rooms with an area of ​​600-800 squares. However, at a summer residence such powerful device is hardly necessary for you. They are often installed in office centers and other large buildings.

In addition, that you need to choose a good repeater, you need to make sure of the quality of the external antenna and cable. This will eliminate the loss of strength and power of the radio signal during its transfer from the repeater to the internal distribution antennas.

And another important point - the installation of the amplifier. It is better to entrust this issue to professionals, especially since in this case you can use warranty service in case of malfunctions, while installing the amplifier yourself, you take full responsibility for yourself.
