PRESS RELEASE

Streamwide, together with its partner Rohill, will give a practical demonstration of the interworking of Mission Critical Push-to-Talk (MCPTT) and Land Mobile Radio (LMR) based on the 3GPP Interworking Function (IWF)
standard at the Critical Communications World (CCW) conference and exhibition in Vienna 21-23 June 2022.

Paris, 21 June 2022 – Streamwide, market leader in mission-critical communications solutions, and Rohill, the Dutch manufacturer of TETRA communications infrastructures, will jointly demonstrate the interworking of LTE
(Long Term Evolution) mission-critical communications systems with LMR (Land Mobile Radio) systems based on the new 3GPP Interworking Function (IWF) standard.

Teams from Streamwide and Rohill carried out the necessary developments allowing the two communications systems to interface in accordance with the new 3GPP-IWF standard. The first live demonstration will take place at the Critical
Communications World (CCW) conference and exhibition.

While LMR communications systems have for years proved their stability and reliability, this narrow-band system was unable to meet the fast-changing operational requirements of critical environments and the increased needs of
broadband data applications. Many organizations which have long used the LMR system are now seeking to upgrade their communications in order to reach new levels of functionality and enhance the security and efficiency of their missions by
adding standardized mobile broadband technologies using dedicated private networks, commercial provider services or a combination of both.

In making new advanced functions available to numerous government users, above all in the field of public security, and also to other users of key vertical markets, the team on mission broadband solution allows operational tasks to be simplified and improves coordination between different teams. Given that the LMR system will continue to serve critical missions for the coming years, the new 3GPP-IWF standard will allow LTE public security systems to integrate with LMR
systems allowing the users to benefit from both worlds.
