Paris, France – ETELM, a leading manufacturer of advanced Mission Critical communications infrastructures, and Nemergent, a working group that specialises in the development of interoperable emergency communications solutions, have announced that they are collaborating on a Mission Critical Push-to-Talk (MCPTT) solution for critical communications over TETRA and LTE. The partnership marks a major step forward for PMR accessibility to multiple technologies on a single unified platform.

The new solution combines ETELM’s 4GLinked infrastructure with Nemergent’s MCPTT Application Server, one of the earliest implementations compliant with the 3GPP R13 MCPTT suite of standards. The combined solution aims to overcome traditional issues associated with legacy systems and their evolution and association to LTE, by bringing to market a fully interoperable and harmonised mission critical communications solution. The new solution fulfils the expectations of all legacy PMR users that are willing to benefit from the broadband services provided with LTE technology.

ETELM’s 4GLinked is a fully integrated platform connecting multiple critical communications technologies (TETRA, DMR, Analog, P25, LTE) over a single LTE EPC core, allowing seamless communications across technologies. The addition of Nemergent’s MCPTT Application Server to 4GLinked brings the application layer which is expected by all mission critical users.

The first deployments of the solution are planned for summer 2017. ETELM and Nemergent will both participate in the 1st MCPTT Plugtests, taking place from 19 to 23 June 2017 in France, which are being held by ETSI in partnership with the TETRA and Critical Communications Association (TCCA).
