SATTRANS repeaters (bi-directional amplifiers) offer a high-quality and cost-effective solution for extending mobile (cellular) coverage in areas with low or inexistent penetration of the GSM signal

As the mobile usage rapidly grows in all parts of the world, very often places with inevitable needs for mobile use are left with weak coverage due to prohibitive costs of wireless networks expansion. Such places may include shopping malls, parking lots, sports arenas, industrial facilities, airports as well as outdoor space in hilly, wooded or urban areas. Repeaters (or bi-directional amplifiers) can also be used to establish or improve coverage on trains, ships, ferries and even airplanes.

The GSM repeater system consists of three key components: donor antenna, bi-directional amplifier and service antenna. The donor antenna takes the signal from a nearby cellular base station. The signal is then amplified by the amplifier and re-broadcast by the service antenna. In the opposite direction, the signal from mobile phones within the repeater coverage is picked by the service antenna, amplified in the uplink stage and transmitted towards the base station through the donor antenna.

Multi-carrier capabilities
SATTRANS repeaters are built on the band-selective technology so they can easily work with several frequency carriers in one area. At the same time, the product can be set up to support only particular carriers if so required by the user. Repeaters are available in three options for one of the three most common GSM frequency bands: 900, 1800 and 1900 MHz. An option for the Thuraya satellite service (1600 MHz) is also available.

Unlimited number of channels
SATTRANS repeaters do not limit the number of simultaneous calls possible in its service area, so the maximum capacity is on a par with the mobile operator’s performance. This is especially important in the conditions of heavy traffic and multiple carriers.

Automatic Gain Control
The Automatic Gain Control (AGC) feature allows operation of repeaters at different gain levels. AGC is indispensable for effectively serving mobile users located in various spots of the repeater coverage and at different distances from service antennas.

Low power consumption
Low power consumption makes it possible to operate the repeater system continuously by using a solar panel of small dimensions.

Compact design
Our repeaters combine the light-weight and compact design with robust performance. The small dimensions of the product result in easy and quick installation and low (if any) site rental costs.

Cost-effectiveness
SATTRANS repeaters are a great means to balance between needs for more capacity and costs for network extension. The product’s excellent performance per price ratio and its low installation and maintenance costs make it an ideal solution not only for network operators and corporations but also for government agencies, small and medium businesses and even personal use.
