Everything you wanted to know about mobile boosters
Each of us has had such a situation that during a conversation the connection of your communication operator was interrupted or lost.
To eliminate this problem, which is especially relevant in the village or in the country, we recommend that you purchase a Sky mobile signal booster. The device will instantly strengthen cellular communication and the Internet.
What is a signal booster?
A cellular amplifier is a radio engineering device that improves the quality of a wireless telephone signal. This device consists of:
- An external antenna
- A main unit
- Several internal antennas
How does it work?
An outdoor antenna is installed on the wall or roof of a building and receives a cellular signal from base stations. Then, the mobile signal received from the nearest stations is cleared of interference and amplified in the main unit of the mobile repeater, after which it is broadcast to the internal antennas.
These local antennas, installed on the ceiling or walls of the room, radiate the processed signal directly to the mobile phones of the users.
When transmitting a signal from a cell phone, the entire retransmission process occurs in reverse order. At the same time, internal antennas catch electromagnetic waves emitted by mobile devices.
The external antenna broadcasts the amplified cellular signal in the direction of the base stations. Depending on the mutual location of the towers of the main mobile operators, narrow-directional or wide-directional external antennas are used.
The main part of the electromagnetic radiation of the external antenna is concentrated in the horizontal plane. Depending on the design of this device, the signal power is already reduced by two times when it deviates from the horizontal by 20-25 degrees, and then sharply tends to zero.
In addition, some external antennas, for example, “log-periodic” or “wave channel” have a narrow horizontal pattern, which allows you to significantly reduce the level of interference and obtain a “cleaner” signal.
Thus, with the correct choice of external antenna and its competent installation on the roof or facade of the building, residents of this building or office employees are not exposed to additional radiation.
How and where to install a cellular amplifier
If you have problems with cellular communication at home, you should pay attention to UCtel services. The company’s employees will tell you what equipment is needed in your particular case, how best to install it, and will familiarize you with typical solutions to similar problems.
After all, for example, to install an external antenna, you need to find an area with the most reliable and stable reception. Effective functioning of all other equipment will mainly depend on this.
You will probably need the installers’ recommendations when installing a cellular signal amplifier:
- First, the amplifier not only receives a cellular signal, but also emits electromagnetic waves. With high power relay equipment and its incorrect installation, the amplification of the cellular signal can become a source of interference. And this is not only trouble for the neighbors, but also a violation of the law.
- Secondly, it is very important to correctly orient the external antenna.
Especially in those cases when the mobile signal comes from different directions – because the operators’ base stations can be located in different places. At the same time, only an experienced specialist with the help of high-precision devices will be able to position the antenna in such a way that the telephone signal from all operators is received almost equally.
Peculiarities of using a mobile communication booster
So, for example, most enterprises have a long-term contract for corporate services with a cellular operator. At the same time, all employees are provided with SIM cards of this cellular operator for conducting industrial negotiations.
In this case, instead of a universal cellular signal amplifier, you can install equipment adapted to work with a specific mobile operator. This will significantly reduce the cost of purchasing equipment – many cellular companies provide significant discounts on “branded” equipment (it is enough to mention 3G-modems, which, when connected to the Internet access service, sound almost free of charge).
In addition, if reception and transmission of the cellular signal will be carried out only from one base station, then a narrowly directed antenna can be installed. The use of such an antenna will make it possible to significantly increase the power of the radio signal and reduce the level of interference even at the time of reception.
Accordingly, it will be possible to get by with relatively low-power equipment during the reverse broadcast of the amplified cellular signal. It is possible that the company’s employees will not be able to call from personal numbers belonging to another operator, but sometimes such a restriction even benefits the production process.
Which cellular signal booster is needed in your situation?
Despite the versatility and high quality of modern amplification equipment, each specific case of unreliable reception requires individual consideration.
So, for example, in large cities such as Moscow, the cellular signal is quite powerful, but distorted by multiple reflections from the walls of high-rise buildings, “noised” by obstacles and weakened by passing through all kinds of obstacles. In addition, “dead zones” are formed in densely built-up areas – areas where there is practically no telephone signal.
In such conditions, only narrowly directed antennas or more powerful amplifiers sometimes help. In remote areas, the situation with receiving a telephone signal is the opposite.
Although the cellular signal is relatively clean and more evenly received throughout the area, its power is sometimes insufficient. Moreover, since electromagnetic waves (GSM range) spread within the line of sight, in rural areas and cottage villages it is desirable to install the receiving antenna as high as possible.
It is even more difficult to ensure high-quality communication in basements, semi-basements, and basement rooms.
Due to reinforced concrete floor slabs, strong walls, and a thick layer of earth, the cellular signal does not penetrate in these places, so there is actually nothing to amplify it. In such cases, a careful survey of the surrounding area is required to determine a suitable location for the installation of the external antenna.
Having studied the projects already implemented in practice, the head of the enterprise or the owner of a private house will be able to independently estimate how much a reliable mobile connection will cost him, as well as what is more profitable – to install all the equipment himself or to entrust this matter to professionals.
