1000 W,  2000 W, 4000 W, 6000 W.

In transmitters is carried out:
— microprocessor control;
— full control and diagnosis of all units of transmitter
— parameters set up by hand or automatic;
— automatic start up at video signal.

FOR MOBILE COMMUNICATION SYSTEM RGSM-900 (ОUT)

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».

Repeater provides increasing of mobile communication range at line of sight of base station.

Repeater amplifies a signal and reduces risk of communication losses 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.

Delivery complete set:
— transceiver module…………………1pc.;
— antenna as «wave channel»………2pcs.;
— connecting cables.

It is possible manufacturing of antennas with a spectral radiation (reception of three operators is provided) on the customer’s request.

REPEATERS FOR MOBILE COMMUNICATION SYSTEM RGSM-900

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.

MULTI — CHANNEL  RADIO SYSTEM OF SYNCHRONOUS TRANSLATION

Multi-channel radio system of  synchronous translation is a complex of hardware for transfer to broadcast speech of orators and for organization  of synchronous translation speech of orators on one or few languages.
Using of the given system allows to increase  level of holding of conferences, meetings and  business meetings with foreigners’ participation.

Common units of the system are: 
— transmitters with telescopic antennas  (it is necessary one transmitter for orators  speech translation and one transmitter for synchronous translation of each language);
— handsets for interpreter;
— radio receivers;
— complex of jumper cables;
Provides:
    — quality and reliability;
— stable work at participants movies in room;
— simultaneous use of any quantity  of radio receivers.
