                          Operator/User Association (OUA) latest update 24/4/19
(no new minutes, just links updates due to new TCCA host)

Note - the OUA meetings have now ceased - the last meeting having taken place on 26 September 2018
The OUA is a forum of operators and users for the sharing of experiences in implementing and operating TETRA technology and informs the TETRA + Critical Communications Association, ETSI TETRA and suppliers on the operational and business needs of TETRA operators. A key responsibility is the production of information and guidance to the Technical Forum relating to their production of the TETRA Interoperability Profiles (TIPs). For this, the OUA produces Service Overviews which define in operational language which features should be included

                            Technical Forum (TF) latest update 25/11/21
The TF is responsible for technical non-ETSI standards aspects of TETRA, primarily the management of the TETRA Interoperability process. This includes the steering of the development of TETRA Interoperability Profiles (TIPs) and Interoperability Certification Test Plans (IOPs). It is also responsible for managing the interoperability testing and certification process

                               Security & Fraud Prevention Group (SFPG) latest update 21/8/21
The SFPG deals with operational TETRA security issues which are not in the scope of the ETSI TETRA security standard. One of the main tasks of the group is to monitor fraud and threats for all types of operational TETRA systems and it produces SFPG recommendations for security and fraud prevention

                         Critical Communications Broadband Group (CCBG) latest update 16/9/21
The CCBG is driving the development and adoption of common global mobile broadband standards and solutions for users who operate in a mission critical or business critical environment*. The CCBG isl also working with the TCCA’s Spectrum Group and PSC-Europe to lobby for appropriate harmonised spectrum in which to deploy critical broadband services and applications
