Critical communications for all professional users


The TCCA (TETRA and Critical Communications Association), was established in December 1994 (known then as the TETRA MoU Association) to create a forum to act on behalf of all parties interested in TETRA technology, representing users, manufacturers, application providers, integrators, operators, test houses and telecom agencies.

Today the TCCA represents more than 160 organisations from all continents of the world, bringing together all those with an interest in the provision of wireless communications in a mission critical or business critical environment. The TCCA believes in the principle of open and competitive markets worldwide through the use of common standards and harmonised spectrum. The TCCA continues to support and promote the use of TETRA technology and is driving industry synergy in the development of future mobile broadband capability for the users and providers of critical communications.

The TCCA is a Limited Company and is registered in the United Kingdom. It is governed by UK Law and, as such, is required to have two legal documents in place. The first is the Memorandum of Association which describes the purpose and principles of the Association.

The second legal document constitutes the Articles of Association. This is a set of legally binding rules and procedures that have been agreed by the Members and which the Board and Chief Executive follow when conducting the business of the Company. The documents are available to members here.

Organisations or individuals that wish to join the TCCA can do so by downloading and completing an application form and sending this to the Association's membership department. Full details and the forms can be found on the How to join page.

The TCCA comprises an Executive Board, which directs the Association’s many activities. Within the TCCA there are also a number of groups that have been formed to specifically support the TCCA’s objectives.

Detailed descriptions of each group's activities can be found in the Membership brochure available on the How to join page.
