RR 2200 is designed for building reliable digital radio relay links with transmission capacity 2 Mbit/sec in the frequency band 2,2 GHz on a lower level of organizational units.

The station can also be used for a connection of special communication (and other) units to the integrated tactical/operational communication system OTKS/TAKOM.

Technical specifications and standardized interfaces ensure connectivity with other technical means of OTKS system and also facilitate the connection of other data terminals using radio relay link for mutual interconnection.

Design of the station facilitates application in different types of communication containers as well as a stand-alone unit.
