The Australasian TETRA + Critical Communications Forum, formerly the Australasian TETRA Forum, is a chapter of the international TETRA and Critical Communications Association (TCCA) and part of more than 160 organisations from all continents of the world bringing together all those with an interest in the provision and development of non-proprietary digital wireless communications in mission- or business-critical environments.
The TCCA also works closely with those that are responsible for the development of standards relating to critical mobile communications. These include ETSI, the European Standards Development Organisation, and 3GPP which develops and maintains standards for public mobile networks.
