How to choose a cellular amplifier: TOP-5 models in the ranking - Setafi

Cellular amplifiers work on the principle of an antenna. They pick up the signals from the base station and amplify them to maintain a normal mobile phone and internet connection. Today, several hundred different types of models are being produced, so figuring out how to choose a cellular amplifier is not always easy. To do this, you need to study the technical specifications, as well as consider specific devices of well-known brands - all this information can be found in the presented article.

Types of amplifiers

A repeater for amplifying a cellular signal can be of different types. Common devices such as an antenna, a cellular or Internet signal amplifier:

1. An Internet signal booster is a small antenna that is connected to a router or modem. It is used only to amplify the Internet signal. Separately, such a gadget does not work - it must be connected to a modem. The device is compact, does not take up much space and does its job well.

2. The amplifier antenna performs the same function, but it is not connected to the modem via a standard USB cable. Communication is carried out using a special high-frequency cable with connectors. Boosts Internet signal and Wi-Fi.
3. Considering how to choose a repeater, you can pay attention to the classic cellular amplifier. Compared to other devices, models of this type have their own antenna. It is placed inside the house and forms a coverage area. Enhances mobile phone signals as well as internet connections.

Amplifier design

To understand how to choose a cellular amplifier for a summer residence, it is useful to understand its device. As a rule, the model is a passive antenna with a USB port for connecting to a modem. Moreover, the kit usually comes with wires with which you can immediately connect to the 3G or 4G module.

There are also models that include a modem with several LAN ports and slots for SIM cards. Depending on the set of accessories, connection to a laptop, PC is carried out via cable or modem, as shown in the diagram.

The rating of cellular amplifiers is represented by the best models, which consist of 3 main elements:

1. Actually the amplifier (repeater).
2. External antenna.
3. Internal antenna.

Each element is connected in series with the other using a coaxial cable. The repeater itself works when plugged into a standard 220V outlet.

Top Cellular Booster Includes 2 Types Models kits:

1. Two-module systems consist of an external antenna and a repeater, which has its own (internal) antenna built into it. Since there are few elements, installation is noticeably simplified. But it should be borne in mind that such a device is not very powerful. Therefore, if you need to understand how to choose a cellular signal amplifier with higher performance, you should consider other models.
2. Three-module consists of a repeater and 2 separate antennas. They are more expensive, but give a stronger signal. In addition, antennas can be placed at a maximum distance to cover the entire network area.

How to choose an amplifier

To select the right model, you need to understand how a cellular amplifier works, as well as what technical characteristics it has. Before buying equipment, it is recommended to pay attention to several parameters.

Type of external antenna

The principle of operation of a cellular amplifier is similar to the operation of an antenna. The device receives a radio wave from a source and converts it into high-frequency vibrations. There are 2 types of external amplifier antenna:

1. Directional - it should be directed only in the direction of the base station, since it is in this case that the signal will really be amplified. Models with a directional antenna are used in cases where the station is located at a great distance.
2. Omnidirectional is distinguished by a small radius of "capture" by the signal, but it better receives reflected waves. Such a device is well suited for areas with dense urban development.

Antenna protection

When studying how to choose a GSM repeater, you need to pay attention to the protection of the external antenna. Usually a plastic or metal box is installed on it. The design looks more attractive and also receives protection from any external influence. Typically, these models use directional antennas.

There are also devices that do not have a box. As a rule, these are omnidirectional antennas. They are cheaper, but lose in terms of aesthetics. In addition, the lack of protection leads to rapid wear and corrosion. When analyzing how to choose a communication amplifier, this point must be taken into account.

Degree of protection

The best cellular repeaters serve without complaints for several years, because they have reliable protection. You can define it in the description of the model according to the IP standard. The minimum requirement is IP40, although it is better to consider equipment from IP55. You can clarify the compliance of the standard with a qualitative description of protection in the table.

Cables and Connectors

If you understand which cell signal amplifier is better for giving, you need to pay attention to the completeness. As a rule, the set contains several connecting elements, including brackets and cables. Models must also be equipped with TS9 or CRC9 connectors. The kit also comes with adapters for connectors.

When analyzing which cellular amplifier to choose for a summer residence, it is best to stop at a radio cable with a resistance of 50 ohms and SMA-type connectors. The connection of such a device is performed according to the specified scheme.

Communication standard

Having figured out how a cellular signal amplifier works, it will not be superfluous to pay attention to the communication standard it supports:

• 2G - allows you to receive only voice calls to phones;
• 3G - in addition to calls, provides Internet access, but only at low speed;
• 4G - provides both calls and the Internet, and at high speed.

Gain

The best cellular amplifier for a summer residence should have a sufficiently large gain. This indicator is measured in dB:

• for models that amplify the Internet signal, the optimal value of the coefficient is from 7 to 20 dB;
• for mobile signal amplifiers - from 25 to 50 dB.

There are models with a higher coefficient. They are installed in the countryside. Moreover, if the signal is weak both at home and on the street, it is better to take a maximum - from 75 to 85 dB. And if the signal outside is good, but weak at home, you should consider devices with 60-70 dB.

Top 5 amplifiers

Considering which cellular amplifier to choose, you need to study several models of well-known brands. If you study the reviews and specifications, you can make the following rating:

1. S2100 KROKS RK2100-70 - amplifies 3G signals. Gain from 60 to 75 dB, covers an area up to 200 m2. Such a device can be used both in a residential area and in a car. The degree of amplification can be adjusted using the manual switch.
2. Titan-900/1800 PRO is a repeater with 2 antennas (outdoor and indoor). Serves all communication standards from 2G to 4G. Designed for large areas up to 1000 m2. Equipped with indicators that allow you to correctly position the device. Has a certificate of the Ministry of Communications of the Russian Federation.
3. TR-900/1800-30dBm - this repeater supports all communication standards and covers an area up to 1000 m2. Works in a wide temperature range - minimum -10, maximum +55 degrees. Receives signals from a station located at a distance of up to 20 km.
4. PROFIBOOST E900/1800 SX20 - the device is powered by a microcontroller, so all settings are performed automatically. Supports all communication standards, has IP40 protection. Designed for rooms up to 500 m2. Reliable model from a well-known brand.
5. DS-900/1800-17 - amplifier dual band type for all communication standards. The power consumption is 5 W, while the gain is 70 dB. Provides coverage of an area within 300 m2. Equipped with a number of smart functions that allow you to position the device in a convenient place and save electricity.

Repeaters provide stable reception and amplification of the communication signal. When choosing a particular model, you need to take into account the characteristics of your area and the remoteness of the tower. So, for a dense urban development or a village, it is necessary to consider models with a maximum gain.
