Pioneering mission-critical mobile services over LTE
The new global standard MCPTT (Mission Critical Push-To-Talk) will replace legacy group communication systems, such as VHF, TETRA, P25, iDEN and others. Based on LTE architecture, it will be available to governmental institutions, public safety organisations as well as commercial users.
The new technology comes with several advantages: On the one hand, this market approach will drive costs down due to economies of scale. Sharing network infrastructure with commercial users ensures adequate capacity for emergency situations, when public safety users have priority over commercial users. On the other hand, MCPTT will foster a faster response and enhanced situational awareness in the event of a disaster by enabling new features like the utilisation of broadband transmission technology.
The LTE technology is currently being implemented worldwide in the safety-critical domain. Preliminary work and the rollout are already in progress in various countries. Frequentis is well prepared for the emerging standards. The 3020 LifeX public safety platform allows the implementation of new technologies such as the above-mentioned broadband communications, while smart devices will further accelerate the development of high-performance safety-critical applications.
MCPTT benefits were proven in a live demo, when Frequentis and its technology partners, Austrian mobile radio provider A1, Italian LTE mobile core network provider Athonet and Spanish MCPTT application provider Nemergent, united to demonstrate the rapid establishment of safety-critical LTE communication infrastructure “at the network edge”.
For this demo, a crisis flood scenario was set up in a power plant. Different terminals and LTE networks were brought together for the solution, consisting of an LTE network from A1, and a 5G-ready complete LTE mobile core network including IMS (IP Multimedia Subsystem) from Athonet. In addition, Nemergent deployed the MCPTT client and server components, while Frequentis provided the control room solution with their Multimedia-Collaboration Platform 3020 LifeX, enabling cross-coupling (LTE, TETRA, Emergency Telephone Calls) and mixing media as well as tracking the resources on the embedded geographical information system (GIS).
Mobile broadband network coverage was combined with a deployable micro system, allowing private and group calls to be established between professional field units and the dispatcher, providing tracking and location information. In various scenarios, the integration of safety-critical communication and broadband applications was displayed by emergency teams wearing helmet mounted cameras streaming live HD video to the control room.

This breakthrough demonstration in mission-critical mobile services represents a further milestone in the collaboration between Nemergent and Frequentis to implement a standards-based control room interface for MCPTT. Staying compliant with current and emerging standards ensures that the company’s systems keep up with future requirements of the most demanding customers.
