The 8th MCX Plugtests in Sophia Antipolis successfully validated MCPTT, MCData, and MCVideo capabilities over LTE and 5G networks using over 1,500 use cases based on 3GPP Release-17. For the first time, the event included off-network device-to-device testing and integrated eMBMS multicast components into a multivendor environment to ensure seamless interoperability. Key focus areas included FRMCS features, Interworking Functions for legacy LMR systems like TETRA, and the execution of conformance tests that will inform future updates to ETSI TS 103 564. The sessions were supported by an observer program featuring presentations on deployment challenges and standards progress from government, operator, and regulator stakeholders.
