Dual band Mobile Signal Amplifier With LCD


Each radio signal, whether it is television or GSM, is distributed unevenly in space, may be lost and weaken. All this leads to the formation of places of uncertain reception and "dead zones", where the signal may be completely absent. The life of a modern person is closely connected with the use of a mobile phone. The need to be in touch all the time and caused the emergence of special amplifiers, called GSM repeaters, to keep the signal at the proper level. 


1.The main problems when choosing an amplifier

The cellular amplifier provides high-quality and efficient reception of the radio signal of the mobile network. GSM repeater, GSM amplifier or GSM repeater are synonymous

2. How to start a choice?

Choose a signal amplifier based on your own needs and conditions for its further operation. Next, we will deal with all the difficulties in steps.

3. A repeater is selected. It's enough?

Solve the problem of strengthening the cellular with only one repeater will not work. Why? As described in our article on the basics of mobile communications, the cellular signal propagates between the operator’s base station and your mobile phone.

Therefore, in order to strengthen a weak signal, it must be taken to an external antenna (usually a street one), pass it through the repeater and send to the output antenna (inside a house, apartment, office)

And of course, it requires a high-quality cable to reduce power losses during the transmission of a radio signal from a GSM repeater to internal GSM distribution antennas


Repeaters can also be installed in any other premises where the connection is unstable, the signal during a conversation is interrupted and unstable. Connecting a GSM amplifier will allow you to always be in contact with business partners, colleagues, friends and family! This will ensure you success in work and the ability to keep in touch at a distance with people close to you! Repeaters can be installed not only to ensure good voice communication, but also to gain access to high-speed Internet of cellular operators (3G / 4G networks). Mobile Internet has now gained immense popularity. First of all, this is due to the advent of modern smartphones that allow you to use not only voice communication, but also to go to the world wide web. You can connect to 3G / 4G networks both on a modern phone and from any other device, like a computer, tablet, laptop. But because of the peculiarities of the transmission of electromagnetic waves, the walls of the house, as well as interfloor partitions and ceilings are an obstacle to the signal and special amplifiers 3g and 4g networks - cellular repeaters are installed to enter the buildings on the Internet. Installing an amplifier is not only an opportunity to get high-quality voice communication, but also a stable 3G / 4G Internet reception.
