Connecting radios all over the world

Sepura Tetra terminals

The Sepura mobile Tetra terminal can be remote controlled either fully through an interface that gives the operator a Virtual Control Head, or through our universal (LE) interface.

The Virtual Control Head gives you full remote control of the radio, just as if you were sitting in front of the radio. You have a full display and all buttons can be accessed from your touch screen, with the PC mouse or by short cuts on the standard keyboard.

Mimer SoftRadio


As with all other SoftRadio you can operate several radios from one dispatcher and each radio can be operated from several dispatchers. Each dispatcher can also use other types of radios in a mix.

All connections are made from one of the control head connectors on the radio. The standard control head can be left connected to the other port and will work in parallel with the virtual control head.

The terminal needs no special programming.

Network Interface: 3009/08
CableKit: 3015

Single Talk Group use

For users that needs only one talkgroup and no other functions from the radio, the Network Interface LE can be used. A system mix of advanced radios and single talkgroup radios are also possible. See example below.

The terminal then needs to be equipped either with the standard control head or with the AIU-box, so that audio can be accessed through them.

Network Interface LE: 3130
CableKit: 3246

Examples of use:

  • Local use when several dispatchers want to share one radio
  • Remote use where a dispatcher at one location want to talk to radio users at a different location
  • Cross patch between Tetra and other two way radio systems, like Airband, Nexedge, DMR, MPT or an other Tetra network
  • Service work, by placing a radio at a remote location in the Tetra network

Typical at a larger dispatch installation is to have a few radios with a fixed talk group (through the Network Interface LE) and a few with a full remote function (Standard Interface).

In this way the dispatchers can monitor all the most important/most used talk groups in parallel.  And depending on need set the full function radios to other talk groups and use them for sending SDS messages etc.
