R&S CMX500 radio communication tester

The R&S CMX500 radio communication tester has been used to successfully validate mission-critical push-to-talk protocol conformance test cases for the Global Certification Forum. With this achievement, Rohde & Schwarz is paving the way for a smooth transition from narrowband TETRA to broadband 3GPP Mission Critical Services (MCS) for device manufacturers and service providers.

3GPP MCS refers to a suite of communications services that are essential for public safety and emergency response operations. It is designed to ensure seamless communications for first responders, enabling efficient coordination and rapid response in critical situations. Often referred to as MCX, these mission-critical services, which include not only MCPTT but also mission-critical data (MCData) and mission-critical video (MCVideo), are designed to meet stringent requirements for reliability, availability and security.

The protocol conformance test cases were developed using the R&S CMX500 radio communication tester and allow engineers to evaluate their MCS applications and devices under realistic conditions. The device under test establishes a real-time, comprehensive connection to the simulated MCS network and tests the relevant signalling and RF scenarios in line with 3GPP specifications.
