Functional for: Orange, Telekom, O2.

It perfectly amplifies the signal inside the building and outside the building.

It is the ideal device for use where there is insufficient signal for your mobile phone and is suitable for any home or business.

Its use is also suitable for various buildings and spaces where gsm coverage is a signal of a heaving (underground and reinforced concrete structures, bars, games rooms, even smaller outdoor spaces) which are shaded by tinting or massive walls.

GSM signal repeater amplifiers, GSM amplifier is used to improve GSM signal in areas with poor coverage.

Various variants of repeater - repeater or signal amplifier of mobile operators (GSM amplifier) are available on the market.

Repeater is suitable in places in buildings with weak or no signal of the mobile operator. The function of the repeater is to amplify and further distribute the amplified signal inside the building.

Repeaters are divided by frequency.

The signal amplifier for the mobile phone (also known as an amplifier or amplifier) consists of three main elements - an external antenna, an amplifier, and an internal antenna.

The mobile phone reception amplifier is a refresher system that includes an amplifier that receives amplification or power reception in different directions. The task of the external antenna is to receive and transmit the signal from the tower (winger) and transfer it to the amplifier. The gain of the antenna is usually not less than 7 dB and can be greater than 10 dB. The antenna is connected to the amplifier itself via a coaxial cable. The main purpose of the booster is to take the existing GSM signal for mobile phones from the antenna and amplify it.

How the mobile phone reception amplifier works.

Signal amplifiers from operators are used in places where the reception of the mobile phone is poor. The strength of the mobile phone signal is usually affected by various obstacles. These include natural obstacles such as trees, building materials in buildings and hills, as well as distance. GSM signal reception amplifier is designated for such locations. The mobile phone signal refers to the signal strength that is calculated in dBm, which the mobile network sends to the mobile phone.

First, the reception of the signal from the mobile phone is captured by an external antenna. Then it is amplified by an amplifier and carried over the building through the internal antenna. The result is amplified signal reception even in more remote places of the house. You can then enjoy cleaner calls and faster internet browsing and fast downloading and uploading data. This is how a mobile phone signal amplifier works in your office or house. This is how all signal amplifiers work on all networks of technology platforms, including GSM, CDMA, TDMA, EVDO, UMTS, HSPA+ and the latest LTE. Data and voice speeds from 2G voice, 3G data and 4G LTE advanced networks are enhanced depending on the amplifier you have called. Another advantage of the amplified signal is that the battery life of the mobile phone is extended by a few days. You can actually select a mobile amplifier, which simultaneously amplifies the signal strength of various mobile phones. The signal strength refers to the size of the electric field at the reference point, which is a little far from the antenna that makes the transmission. The signal strength is also known as the field strength or the signal of the received level. When you speak on your phone, the cell phone turns the voice into electrical signals and sends it like radio waves. The phone of the person you're talking to converts electrical signals into a sound that an individual can hear.Any mobile phone signal amplifier for a domestic, automotive or naval ship works to amplify this transmission.

Signal strength.

The coverage of the location by mobile signal on where you want to mount the external antenna determines the total area that needs to be covered, for example, in the office or at home. If the external reception is strong enough, you can easily cover an area that is about the same size as the coverage area shown on the repeater. On the other hand, if there is a weaker external signal, the internal area to be covered shall not be the same size as indicated on the signal repeater. You can also turn to the display on your phone to assess the power of coverage. This will help you estimate the best place to connect an external antenna.

MGC , skratka Manuálneho ovládania zisku, - MGC stands for Manual Gain Control

is a state-of-the-art technology to mitigate interference. The adaptive and innovative MGC mechanism allows users to manually adjust the profits of the mobile repeater. Simply click the "Add (+)" or "Reduce (-)" button, the internal MCU single-chip microcomputer immediately changes the gain of the amplifier and also displays the current gains on the LCD screen.

Advanced MGC circuit design can greatly optimize the quality of cellular conversation, reduce interference on the BTS cell phone signal tower and avoid self-oscillations in the repeater system.

Automatic profit control - AGC - Automatic gain control

Automatic Profit Control (AGC; also called automatic voltage amplification) is a feedback control circuit designed to provide a controlled signal amplitude on its output, despite changing the amplitude of the input signal. The average or peak level of the output signal is used to dynamicly adjust the I/O gain to an appropriate value, allowing the circuit to work satisfactorily with a larger range of input signal levels. It is used in most radio receivers to compensate for the average volume (volume) of different radio stations due to differences in the intensity of the received signal, as well as variations of the radio signal of one station due to fading. Without AGC, the sound emitted by the AM radio receiver would differ from a weak to strong signal to extreme; AGC effectively reduces the volume when the signal is strong and increases it when it is weaker.

How it works

The signal to be controlled by the amplifier (radio detector output) goes to the diode and capacitor that produce peak DC voltage. This is fed into rf amplation blocks to change their bias, thus changing their profit. Traditionally all phases controlled by profit have come before signal detection, but it is also possible to improve profit management by adding an amplified degree after signal detection.

ALC Automatic power level control with adjustable coverage

ASF Auto-off feature is available for both uplink and downlink

Note: The operation of GSM repeaters is possible in the Slovak Republic only on the basis of an individual authorisation issued by the TU SR (ÚrekaPS). Only operators to whom the relevant frequency band has been assigned may be holders of such authorisation. Another person may obtain authorisation provided that it is demonstrated by the consent of the operator whose frequencies should be used by the repeater. The GSM repeater does not fall under the general authorisation issued for GSM network terminal equipment unless it is mobile...

The equipment can only be used in the territory of the Slovak Republic within the meaning of § 36 of Act 351/2011 on electronic communications.

Installation steps

Step 1 Start by taking your phone up to the roof or other place outside to find where the signal is strongest.

Step 2 Temporarily mount the external (outdoor) antenna in this place. You may need to set up and move the antenna later.

Step 3 Lower the coaxial cable into the building so that you can move comfortably (attic, etc.), where you can also get standard performance for the signal repeater.

Step 4 Place the signal repeater in this location and connect the coaxial cable to the outside of the signal repeater and the external antenna.

Step 5 Install the internal (internal) antenna in a productive position. You may need to adjust or move the antenna later. More notes on Indoor Antennas and Patterns here.

Step 6 Connect the coaxial cable between the internal antenna and the Signal Repeater output port.

Step 7 Turn on the system and check the signal inside the building. If necessary, tune the system by dragging or directing the external and internal antennas until they reach the maximum possible signal.

Step 8 Secure all antennas and cables, securely mount the signal repeater and clean the installation.

Of course, there are still a few things to consider, but in general it is a basic procedure. For more information, please contact us. Step-by-step instructions for the adjustment provided for the goods.
