R&S®GB4000C/ R&S®GB4000V pairing for VoIP operation

Your task

Operators must use and control a variety of stationary radios at constricted radio sites. Setting up such sites is a challenge due to extremely tight space that limits the number system components such as computers, servers, or voice communications equipment.

Radios are used for civil and military air traffic control (ATC), maritime communications and military ground‑air‑ground communications and must support a broad array of radio waveforms.

Small systems must also be highly reliable, easy-to-use and have a favorable cost/benefit ratio.

Rohde & Schwarz solution

The R&S®GB4000C/R&S®GB4000V pairing for VoIP operation makes it easy to set up the smallest systems that use an exclusively IP based communications infrastructure. The R&S®GB4000C remote-control unit automatically establishes the VoIP connection between the paired R&S®GB4000V and the selected radio.

The IP based design makes it possible to build straightforward systems that consist of just a few components to save time and space during setup, conceptual design, and commissioning.

Application

An R&S®GB4000C remote control unit is paired with an R&S®GB4000V audio unit. The remote control unit has three functions: operating and monitoring a previously selected R&S®M3SR Series4400 radio and controlling the establishment of a VoIP session link for the audio unit.

A functional pair is defined within the radiocommunicationssystem by assigning the R&S®GB4000V audio unit to an R&S®GB4000C remote control unit. When a radio is selected using the remote control unit, the assigned audio unit automatically establishes a VoIP connection to the radio and voice transmissions can be sent and received immediately.

Several R&S®GB4000C/R&S®GB4000V pairs can be used within a communications system. One R&S®GB4000C can control a radio while other control units have monitoring access to the same radio.

The concept of two separate units for control and audio allows the two units to be spatially separated for greater flexibility in implementing a broad array of application scenarios.

The R&S®GB4000V audio unit and R&S®M3SR Series4400 software defined radios support VoIP in line with the EUROCAEED-137 standard.

R&S®GB4000C/R&S®GB4000V pairing for VoIP operation is available for radio software version 23 and higher.
