Deutsche Telekom offered a first glimpse at a technology developed to open TETRA networks to all mission-critical services organisations, providing connectivity regardless of the technology they use.

The operator demonstrated the expansion to its T Mission portfolio by using a smartphone to communicate in a 5G network using a TETRA radio.

Deutsche Telekom explained the test used Motorola Solutions’ latest mission-critical technology and proved this could interact with TETRA set-ups.

This means German public safety organisations can continue using existing radio infrastructure in mission-critical services, with the combined network approach boosting coverage and resilience.

An enhanced T Mission video function was also demonstrated. It enables control centres to transmit up to ten different streams to defined groups and Deutsche Telekom pointed to drone, security and body camera footage as examples.

The operator also showcased a GUI for sensor data developed in conjunction with electronics manufacturer and distributor ATS Elektronik which enables real time monitoring of data including pulse rate and body temperature.

Deutsche Telekom stated this is being used by firefighters, though emphasised its potential for other emergency services personnel.

The demonstrations took place during specialist trade show PMR Expo in Cologne last week, though Deutsche Telekom only publicised the developments today (2 December).
