Overview 5 kinds of the best cellular signal amplifiers: how to choose which one to buy, the pros and cons, features, rating

Cellular operators annually expanding coverage, and the market is constantly there are new providers of mobile internet services. But often in suburban homes, and sometimes in apartments located even in the city, covering all missing or the quality is not enough for a normal mobile phone use for other purposes. In such situations, the position is able to correct a special device called a GSM amplifier repeater or repeater. Its task - to take a weak signal from the base station, amplify it, and then establish its coverage area, which area depends on the device characteristics.

How to choose a cellular signal booster

The choice of amplifier is based on the specific conditions of use. Ensuring a stable coating in a country house for 1-3 rooms, a city apartment or a car, which does not need a large working radius repeater requires the purchase of a completely different amplifiers. Matter and supported communication standards, in other words - the frequency bands which will be amplified. The following are the main aspects of the choice of the amplifier for specific tasks.

cellular standards

First, it should define its needs. So, for a stable mobile Internet will require a powerful receiving antenna and repeater supports 3G standards or 4G. To improve cellular communication, can be quite inexpensive GSM-repeater. Specific standards of operators are specified in the operators themselves. The fact that each of them can use the frequencies 900, 1800 and 2100MHz.

The amplification factor (KU)

From this parameter depends on the ability of the equipment to ensure the normal coverage at a particular signal level reaching the installation location of the repeater from the base station. The signal level in the home is determined through the use of several phones or even a mobile one. The better the coating, the less powerful amplifier is required. So, if on the phone screen displays the level of communication with one or two divisions corresponding to the scale when the test held indoors and outdoors, for example, displays all of the finishing touches need a repeater with a gain about 65 dB. In the case of a weak signal in the house, and the street is selected amplifier with 75 dB or more.

When selecting the amplifier is recommended to exclude variants KU of less than 60 dB, since their functionality is often severely limited. For example, during operation, noise may occur if within the network are a few phones.

coverage

This parameter, roughly speaking, determines the size of the room, which is able to cover the amplified signal repeater. When choosing a power amplifier draws attention to its power output and range. For example, the amplifier 100 mW is sufficient to cover the area of ​​200 sq.m. At the same time, an area of ​​800 square meters require a repeater capacity of about 300 MW. When buying better to make a small margin on the coverage area, but excessively high power amplifier for specific operating conditions had not justified itself. This is especially true cost.

Antennas and cables

Antenna and connection cables - not the last point, to which you should pay attention when buying an amplifier. As mentioned above, the repeater receives the signal, amplifies it and "sends", creating a coverage area. For the first and last two actions are required of the antenna connected to the block repeater cable. On the quality of the signal loss depends directly on the site of the antenna - a repeater, thus it must comply with the equipment. As for antennas, the use of at least one of each type:

• External. Often this is an all-weather option, which is set in the streets as high as possible (preferably in open terrain). The external antenna is required to receive a signal from the cellular base station operator.
• Internal. It signals necessary for stabilization and amplification of the transmission inside the premises where it is installed. Some models are equipped with built-in antenna amplifiers, while others require a separate connection options.

When installing the antenna must be remembered that their signals can overlap that would create interference and a significant deterioration of the amplifier. It looks like this is if you bring microphone to a working speaker. For this reason, the maximum separation between the antennas themselves.

External antennas are also divided into:

• Omni-directional (omni-directional). In fact, represent a common vertical pin uniformly receiving a signal from any direction, but not able to strengthen it. Almost all internal antennas - omnidirectional, only in this case, they emit a signal in all directions, and do not accept.
• Directional - are used for signal amplification and guided at its source, sometimes up to a degree. In other words, the signal is amplified by the repeater is not only, but also such an antenna.

As for the directional antennas, in most cases, it is used:

• Panel - mainly used to enhance the 3G and 4G. Compact, easy to install, less demanding on the orientation.
• Yagi (wave channel) - classical antenna with a large gain. Demanding to positioning accuracy, have dimensions, and therefore susceptible to icing in the winter and wind gusts.

Cable repeater antenna itself are chosen with suitable connectors to each other. Do not be amiss to ask the manufacturer or retailer, how complicated installation and connection. It is generally recommended for the installation of components and configure them to invite experts, in order to avoid not only bugs, but also damage to the individual pieces of equipment.
