The Australasian TETRA + Critical Communications Forum (ATCCF) is a chapter of The international Critical Communications Association (TCCA) that brings together all those with an interest in the provision of standardised mission and business critical RF communications. We believe in the principle of open and competitive markets worldwide through the use of common standards and harmonised spectrum. TCCA continues to support and promote the ongoing development and use of TETRA and other standardized narrowband technologies and is driving industry synergy in the development of future mobile broadband capability for the users and providers of critical communications. In so doing TCCA works closely with global standards development organisations who develop and maintain relevant standards including ETSI, the European Telecommunications Standards Institute and the 3rd Generation Partnership Project (3GPP) that unites [Seven] telecommunications standard development organizations.
