ETSI, with the support of the Critical Communications Association (TCCA) and the Union Internationale des Chemins de fer (UIC), is organising the tenth MCX Plugtests™. Co-funded by the European Union (EU) and European Free Trade Association (EFTA), this Plugtests event will take place in the ETSI premises in Sophia Antipolis, France.
The concept of Mission Critical Services such as “Mission Critical Push To Talk” (MCPTT), “Mission Critical Data” (MCData) and “Mission Critical Video” (MCVideo) started with 3GPP Release-13 and is ongoing in current Releases. The goal of this MCX Plugtests event is to validate the interoperability of a variety of implementations using different using different multi-client / vendor complex scenarios based on 3GPP Mission Critical Services. The format of the event will be live testing conducted face-to-face over 4G and 5G Networks. This Plugtests event will focus on the 3GPP Releases 18 and 19.
Specific focus will be put on cross communications including the Interworking Function (IWF) to other technologies like TETRA and P25 and the inter MCX scenarios (enabling the connection of different systems, agencies or countries). The tests are based on 3GPP, ETSI and IETF standards and are designed for:
This event will feature tests with 4G and 5G radio equipment (gNBs, eNBs, 5GCs, EPCs, UEs) and will also allow Over-The-Top (OTT) testing of Mission Critical Servers and Clients. Test Equipment vendors will have a possibility to test as well in the Plugtests event.
New vendors and observers must sign the Rules of Engagement and NDA of the MCX Plugtests programme to participate.
Please note that due to space limitations at the venue, a maximum of two delegates per equipment may attend in person.
Observers are welcome to help define the scope (i.e. functionality to be tested) for this event and to evaluate the tests statistics in the TRT (Test Reporting Tool).
In parallel to the testing, we are planning to organise an observer round table discussion, an observer programme with presentations and interoperability demos. The focus of the observer round table discussion and programme is to examine and discuss the progress of deployment and the challenges in testing of the Mission Critical Services for Public Safety and Public Transport. The observer round table discussion and programme will be held onsite during the event.
The interoperability demos will be performed by the interested vendors showing interoperability of their equipment by showcasing the MCX Plugtests test cases and observer scenario use cases.
REGISTRATION
The deadline for organisations to register was 13 February 2026. Registered organisations who wish to add team members after that date can do it by contacting [email protected].
All participants are expected to register to this event even if they participated in previous events part of the MCX PlugtestsTM programme. All participants must register individually. Each first person from an organisation to register for the event is de facto the official contact for technical and logistics matters. After registration, all participants joining this Plugtests will be invited to the preparation conference calls and be subscribed to the Plugtests mailing list dedicated to the MCX Plugtests event. Participants who joined the MCX Plugtests programme during one of the past MCX/FRMCS Plugtests events will by default remain on the dedicated mailing list and will receive invitations to the conference calls on this mailing list. The event is free of charge.
NDA
By registering for the 10th MCX Plugtests event, new participating organisations will join the MCX Plugtests programme and will be asked to sign the Rules of Engagement (RoE) and Non-Disclosure Agreement (NDA) which they will receive upon registration. These RoE and NDA will cover the series of remote and face-to-face Plugtests events which will be held as part of the MCX Plugtests programme.
Companies which previously signed the RoE and NDA of the MCX Plugtests programme when registering to one of the past MCX/FRMCS Plugtests events, will not need to sign the RoE and NDA again: only new organisations joining the programme will receive the RoE and NDA for signature. Upon signature of the RoE and NDA sent to the official contact, the new participants will receive their credentials for the 10th MCX Plugtests wiki. Participants will not be allowed to participate in the event if the NDA of the programme has not been signed by a representative of their company. The deadline to return the signed NDAs to ETSI is 20 February 2026.
This event will take place in Sophia Antipolis, France. Vendors participating in over-the-top testing and Observers will be allowed onsite.
