Phone communications have an important place in the functioning of our society. Poor network coverage can prevent you from accessing the Internet and making smooth calls. Fortunately, an amplifier of this type can overcome these problems at an affordable price.

What is a GSM amplifier?

The purpose of a GSM amplifier, or GSM repeater, is to amplify the mobile signal. This device helps to boost the signal reception of our smartphones and thus allow better reception.

The 4G amplifier can be installed in a private home or in a professional setting. Examples of places that can accommodate a GSM amplifier: Home, office, boat, warehouse or factory, underground parking.

In England, not everyone benefits from the same network quality and many French people encounter difficulties during their telephone calls. In question, the GSM coverage of our country, dense in agglomeration and sometimes difficult to access on the rest of the territory (white zones). Finally, a large number of professional premises do not allow uninterrupted telephone calls because of their size or their location not or poorly covered by telephone operators.

If network coverage is nonexistent or you are located in a white area, the GSM repeater will not be able to amplify the signal. The amplifier's external antenna must be able to pick up a signal outside your home or business premises before amplifying it.

What is the GSM amplifier made of?

A device of this type is made up of three parts, interconnected by a coaxial cable so as not to lose signal quality: An antenna placed outside receives the signal, the amplifier improves it and the antenna interior placed where you make your calls repeats the amplified signal.

This makes it possible to obtain a good mobile network in a place which initially does not allow making calls with a smartphone.

What is the GSM amplifier made of?

Outdoor GSM antenna : Oriented towards the nearest operator antenna and attached at a height, on the roof or on a facade, the latter picks up the upward and downward signal.

Different types of external antenna exist, depending on your environment and the distance to the operator antennas: Omnidirectional, monodirectional, omnidirectional plate with tubes. The omnidirectional antenna is ideal in urban areas since the signal is high and comes from multiple directions. In rural areas, it is recommended to turn to a directional antenna capable of picking up a distant signal, provided that it is well oriented.

GSM amplifier (repeater) : This electronic box improves the signal. First of all, it receives a quality signal from the outdoor antenna.

Then, this signal is recalibrated and transmitted to the smartphone by the antenna placed inside. The gain of an amplifier can be variable, depending on the quality of the signal received by the external antenna.

The latter is selected according to the frequencies of the operator. Some operators use the 900, 1800 and 210 Mhz, others do not. The mono, bi or tri-band GSM amplifier must be chosen carefully to match the frequencies of the mobile operators within signal range.

In the amplifier market, the main difference is in the supported frequency bands (3G, 4G, both ...) and in the number of internal antennas included or possible to add later.

Indoor GSM antenna : The indoor antenna should be placed close to where you are calling. Captured by the outdoor antenna, the signal is then amplified by the repeater and then the indoor antenna broadcasts the improved signal. It can be used in various and varied places (home, warehouse, office, car, boat).

Several options are available to you for optimal operation:

- The panel antenna, oriented towards a precise location and ideal in the event that it is necessary to cover several floors or long corridors.

- The Dome antenna broadcasts the signal in all directions. It is therefore recommended for better network coverage in large spaces.

Although usually included in GSM amplifier packs, the indoor antenna can be purchased separately if you need an antenna with better performance or more suitable for your situation. A faulty antenna can also be replaced.

How to choose my GSM amplifier (Signal booster)?

Do you have network problems? You do not know how to choose your GSM amplifier?

A large number of parameters must be taken into account when selecting your mobile amplifier. Start by finding out what frequencies your mobile operator uses depending on whether the device is connected to the 2G, 3G, 4G or 5G network.

The different parts of the GSM repeater

How to choose the cable?

To obtain the best possible performance, the cable used between the outdoor antenna and the network amplifier (repeater) should be as short as possible so as not to affect the signal.

How to choose the outdoor antenna?

The external antenna must be able to withstand the elements. Plastic antennas are therefore not recommended. Aluminum and steel are preferred.

How to choose the indoor antenna?

In urban areas, we recommend that you choose an omnidirectional antenna as the signal comes from multiple directions.

In rural areas, the directional antenna will be better able to pick up a distant signal, provided it is oriented in the right direction.
