Funktel und TETRA

The future of professional mobile communication

With its TETRA handsets, funktel sets the benchmark in terms of functionality, user-friendly operation and ease of use.

Optimal ergonomics, comprehensive protection against external factors as well as comprehensive TETRA performance features give the FT5 and FT4 (Ex) series the competitive edge.

In addition, the FT5 S  and FT4 S (Ex) Security versions offer high-quality integrated sensors for personal security with manual and automatic alarm initiation as well as localisation functions—even within buildings. All devices are available in the 380-430 frequency band; the FT4 series is also available in the 410-470 MHz frequency band. 
Maximum future-proofing is ensured by a continuous process of further development and seamless integration with existing funktel security systems or TETRA infrastructure. 

The TETRA FT5 handset offers an optimal ergonomic design and complete protection against external influences without compromising on features and functionality. 

All of the previous TETRA features according to ETSI standard remain available, along with state-of- the-art technologies such as Smart Ready Bluetooth for audio connection and location, a 4-way satellite receiver and the unique high power transmission for optimal radio connection.

The FT5 maintains its sturdy, dustproof and waterproof housing (IP65), but is much smaller, lighter and more manageable than most TETRA radios on the market, offering an ultimate portable and comfortable hand-held device.
