Applications include mining, the military, government agencies, emergency services, rail, and transport services. The common mode of operation for TETRA radios is in a group-calling mode in which a single button push will connect the user to the users in a selected callgroup and/or a dispatcher. If enabled by the subscriber management, TETRA terminals can act as mobile ("cell") phones, with a full-duplex direct connection to other TETRA users or the PSTN. Emergency buttons, provided on the terminals, enable the users to transmit emergency signals to the dispatcher, overriding any other activity taking place at the same time. In addition, there are a number of very attractive features such as DMO (Direct Mode Operation—where two terminals can be used without the network) and Gateway mode—where a mobile radio acts as a TETRA repeater for portables in its near vicinity). In short, TETRA is the perfect “in-between” technology for organisations requiring combined cell phone and traditional radio-style tactical communications. It is also very cost effective for multi-site fleets of more than 100 terminals.

DAMM BS421 base station
A popular choice of configuration of this system is the mast mounted option, the BS421 single and dual carrier system. The DAMM BS421 is a single-carrier TETRA base station and is a supplement to the existing 2, 4 and 8-carrier DAMM BS41x TETRA base stations.
The BS421 can be used as base stations in large networks in areas where moderate traffic capacity is required (up to 7 Erlang). The BS421 is developed to be used, together with the DAMM SB421 Service Box containing the base station controller software, as platform for small and low cost stand-alone TETRA systems.
The BS421 base station is designed to be mounted in the top of a mast close to the antennas. This eliminates the traditional degradations due to feeder loss and reduces the cost considerably. It is also ideal as a movable base station mounted in a truck or on a ship. It is designed for harsh climatic environmental conditions and is fully IP65 sealed.
The BS421 is provided with full dual RX diversity for optimal sensitivity, and has a built-in duplex filter with an output power to the antenna connector of up to 10W. With the elimination of the normal feeder loss it has a Radio performance superior to most other available solutions.

STP8000 Hand Portable TETRA Transceiver
The latest TETRA radio from Sepura is a high performance, rugged hand-portable designed to be worn on the belt, but is of suitable weight and size to be worn elsewhere.
The STP8000 has been designed to perform in the most demanding operational environments - breaking new ground in TETRA.
The RF Power can be incrementally set at any level up to 1.8 Watts in TMO, DMO and as a DM repeater, delivering reliable communications when most needed, extending coverage beyond the reach of typical hand held radios.
The largest front-facing loudspeaker available in a TETRA hand-portable provides powerful, clear audio and alert tones, even in the noisiest environments.

SRG3500 TETRA Mobile Transceiver
Control-room and in-vehicle radios are at the epicentre of your operation. And data functionality will be as important as voice to keep essential information flowing and decision-making timely and accurate.
When you choose Sepura's mobile radios you are assured of a reliable hub for your communications. All Sepura radios share our standard user interface so that users need little training to make best use of the comprehensive functionality. A range of mounting options make them suitable in trains, planes, emergency vehicles, cars and on the desktops while optional GPS functionality will enable you to track and better deploy your field force. They can be configured for one, two or no consoles and offer a high number of data ports so you can run the applications that drive your operation easily.
With up to 10W of power, our mobiles will provide coverage at greater distances from TETRA base stations. And when set to gateway mode, the RSG3500 can extend the coverage of your TETRA communication still further.

SRG3500 Tetra Gateway/Repeater
When it comes to advanced mobile radio communications, the SRG3500 is hard to beat. This top-of-the-line radio comes with built-in gateway and repeater functionality. In gateway mode it forms a bridge between the trunked TETRA network and a number of individual hand-helds, giving improved access to the network in areas of poor reception. In repeater mode it acts as a powerful mobile base station for a number of hand-helds in the field, which are operating separately from the TETRA network.
A range of accessories enables the SRG3500 to be mounted in a car or emergency vehicle, on a motorcycle, in a covert vehicle or marine vehicle.
The SRG3500 can be fitted with a GPS module to enable advanced location-based functionality.
