It is intended for increasing of GSM mobile communication service zone in places with a low level.
Repeater’s using allows provide a reliable phone communication in places with impossible communication for some reason.
To a category of such places are referred so-called, «shadow areas» — basements, hangars, shopping centers, vestibules, or premises with thick walls.
The repeater amplifies a signal and allows stabile phone communication reducing risk of its loss or interruption at the lowest signal level.
Advantages:
-decrease of a microwave irradiation of the subscriber at the cost of a power decreasing, demanded for reliable reception;
— increasing of accumulator work duration without recharging of a battery.
At base station direct visibility the repeater installation is simple and does not demand the special equipment.
Delivery complete set:
- transceiver module………….. 1pc.;
- antenna as «wave duct»………1pc.;
- connecting cables.
It is possible manufacturing of antennas with a spectral radiation (reception of three operators is provided) on the customer’s request.
