Mobile relay station R-414 MC in the four directions, is designed to provide radio relay lines, operating in continuous mode in the network of special purpose of the strategic, operational and strategic and operational management level.
Main characteristics
The equipment allows the station:
- the formation of the four microwave links with a programmable variable bandwidth of 2.45 Mbit / s up to 78.4 Mbit / s;
- joint transmission of E1 and Ethernet streams with flexible reallocation of E1 and Ethernet traffic flows within the bandwidth;
- support system configuration "0 + 1", "2 + 0" (without buffer) and "1 + 1" with different types of redundancy trunks;
- monitoring and control of radio link via software;
- align the antennas correspondent in azimuth and elevation,
- switching channels
- selection of channels.
Structure
The structure of the radio relay station 414 P-MP includes:
- the car antenna with a support "Pine-M";
- trailer hardware.
Composition of machine antenna
Machine equipment with an antenna support "Pine-M" and AFU located on an open platform KaMAZ-63502 established terrain directly to the vehicle chassis.
Composition hardware trailer
The structure of trailer hardware P-414 MC includes K2.131 body mounted on a special trailer 2 Mo 4.
Microwave equipment provides communications at intervals up to 45 km (open and semi-open).
