Radio-relay station (RRS)

PURPOSE

    Radio-relay line (RRL) of DS-CDMA standard is intended for wireless voice and data transmission within 1600 km (32 intervals) and for providing  telephone services, Internet access, holding of videoconferences.

POTENTIALITIES

• Construction of multihop (up to 32 intervals) radio-relay communication lines.
• Communication line construction in areas with unfavourable geography for signal porpagation (mountainous terrain, watery waste etc.).
• Transmission of confidential information without use of additional cryptography algorithms.
• Digital stream branching (1Å1) of central trunk line (4Å1).

FEATURES AND ADVANTAGES

Scrambling and noiseless coding.

• Ensures high noise immunity of the line against disturbances from both other transceiving devices and landscape and/or city buildings.
• Ensures high level of confidentiality of transferred data without use of additional cryptography algorithms.

Intellectual algorithm of adaptive power change.

• The central station automatically changes (depending on required quality of data transmission) output signal power ensuring in this way saving of electric energy and improving electromagnetic compatibility indexes.

RAKE receiver.

• Ensures serviceability of the system under conditions of multipath signal propagation.
• Increases stability of RRL operation and continuity of data (voice) transmission  along  the whole extent of communication line.

Remote monitoring and control system.

• Gives the possibility to control any transceiver in the system and remotely analyze the quality of transferred data by means of connection of a PC to any radio-relay station in the line.

SoftwareRadio function.

• Gives the possibility to programmatically configure the functional parameter set of the RRL as applicable (without any change in the equipment configuration).

Developed in Russia.

• The developer adapts the equipment according to the requirements of customer and provides after-sales services.
