Hytera Mobilfunk GmbH is developing LTE-based Next Generation Critical Communication system
The system will integrate narrowband and broadband on one single platform to ensure reliable interworking between the different radio access technologies.
Hytera Mobilfunk GmbH is currently developing the LTE-based Next Generation Critical Communication system at their German-based research and development centre near Hanover. The system will integrate narrowband and broadband on one single platform to ensure reliable interworking between the different radio access technologies.
At the TETRA World Congress 2011 in Budapest a first prototype of TETRA and LTE interworking was shown to the public. The demonstration system has been enhanced with a smartphone-based PMR user agent on the end user equipment and is presented at this years TETRA World Congress in Dubai.
With the integrated SIP-based core server, service interaction between narrowband and broadband is ensured. Group calls with priorities as well as text messaging throughout the system can be demonstrated. Video captured with the end user equipment can be transferred to a central dispatcher and can also be received from a stationary camera.
This proof-of-concept for broadband-enriched voice services over LTE is an important milestone for the evolution of the TETRA system ACCESSNET-T IP by Hytera Mobilfunk GmbH.
