What is a repeater? What is a repeater?

Mobile communication has long been a familiar part of our lives. Being “out of the access zone”, we experience discomfort, isolation. Unstable GSM / 3G / CDMA communication is typical for areas remote from base stations, semi-basement offices and shopping centers, tunnels. Consider the most popular solution used to improve the quality of communication and operators, and subscribers (individuals and organizations) - repeaters or repeaters cellular.

A repeater is a signal repeater. - repeater, rus. - repeater. The repeater / repeater is designed to transmit a signal, repetition of frequency and amplitude. In cellular communications, a repeater is used to repeat and retransmit a signal received from a base station to a place where it was absent or was low. The basis of the repeater - repeater is a two-way cellular signal amplifier. The task of the cellular amplifier is to accept, amplify the signal, to spread in free space. The gain of the repeater depends on the cellular amplifier used. Repeater - repeater can be used for a variety of needs.

So what is a repeater / Booster?

Repeaters are also called amplifiers, boosters, repeaters - these are the names of the same device. But the essence remains the same.

The zone of uncertain wireless coverage can be located both inside (office buildings, garages, multi-storey buildings, large shops and hotels) and outdoors. Outside the premises, a low signal level may be caused by the terrain, for example, hills, lowlands, deciduous forests and high-rise urban buildings. All of these factors lead to a weakening or complete attenuation of the GSM / 3G / CDMA signal.

The solution to the problem of poor coverage can be the installation of an active gain system, designed for use in various installation options. Below is an example of installing a repeater with an antenna system in a residential building. The amplification system provides an effective solution to this problem by redirecting, filtering and amplifying the existing signal on the donor antenna and then directing it to the area of uncertain coverage through the service internal antenna / antennas.

One full kit consists of the following elements:

External/Outdoor antenna (installed on the roof or on the wall of the building, the antenna is target to receive a signal from the base station - towers of cellular operators);

Repeater/Booster (for receive signal is cleared of all sorts of interference and amplified, then the signal is transmitted to the internal antennas);

An internal(Indoor) antenna (Receive the signal from repeater/booster and broadcasts it to the house space around you).

Mobile amplifier

This repeater including two frequency:

900MHz(2G) and 2100MHz (3G). Two frequency can working at same time.

Amplify both 2G and 3G signal. Not only for calling. but also improve the data quality for your mobile.

Signal Repeater for moible phones

Everyone use cell phones. These devices are used to provide communication between company employees.The signal booster have A distinctive feature is ease of installation, autonomy and reliability.

There are cases when have weak signal. To increase it, radio signal repeaters are used.

In this case, the mobile signal repeater for signal stations operates on a duplex type: a signal is simultaneously received and transmitted. At the same time, the received signal is cleared of interference and amplified, and then transmitted.

Repeaters for walkie-talkies are tuned to two frequencies. The first frequency is configured to receive the signal, and the second - to transmit it. To increase the range of the repeater, the device is installed at the highest point of the room or area, and is also equipped with amplified antennas.
