TETRA Radio System

Hand-held Products

When you choose TETRA radios for your organisation you want to be sure that they will perform well in all the situations your users encounter. Versatility, ease of use, resilience and cost-effectiveness will be high on your list of priorities. Look no further than the range of truly international, feature-rich hand-held TETRA radios, with support for many languages and frequencies.

They are the smallest and lightest hand-helds you can buy, yet rugged enough to withstand the rigours of field operation. Their performance is without question, having been proven in over a billion hours of successful operation. What is more, programmable keys, a choice of screen types and GPS functionality, together with the wide range of accessories available, mean that you can customize your hand-held to meet the needs of your operation exactly.

Our radios need little training to operate and are highly reliable. They share the standard user interface, and support tools and many accessories are common across the range, making them highly cost-effective in a mixed fleet.

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 mobile radios you are assured of a reliable hub for your communications. All 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.
