Field test results carried out by the OOO “New Technologies Center” showed that to ensure reliable radio communication between an alert force and subscribers of the radio communication network in the open public space using portable radios with RF power less than 5W, it is essential that the following requirements to the base equipment location be met:
Transceivers (remote access stations) shall be spaced by the distance of less than 15 km, and the receivers – by less than 5 km (the coverage radii ratio for transmitters and receivers being 1:3).
Since the area of responsibility for each rifle team is not in excess of 10 km (excluding tunnels), then to ensure radio coverage for one area it is essential that one remote access station with RF power not more than 10W be installed, and in case of a complicated areas (tunnel, track bends, relief specifics) additional remote access stations of lower RF power will be required.
In the buildings for the rifle teams, the team boss is provided with the 5-channel “Dispatcher” software to ensure interaction between rifle teams, both between riflemen and with other establishments, if necessary, (MIA Transport Headquarters, EMERCOM, MIA).
The guard house is equipped with the KD-02 Dispatcher Console (Remote control set) with a headset to ensure communication between duty officer and riflemen within the area of responsibility of his rifle team, and nearby rifle teams.
