TCCA - The Critical Communication Association

The TCCA leads the global development and promotion of standardised critical communications solutions for professional users. The TCCA provides a forum for governments, regulators, manufacturers, operators, end-users – for any and every stakeholder in the critical communications sector – to discuss, debate, deliver and evolve the market for the benefit of all.

The TCCA influences key decision makers on the need for and benefits of open and competitive markets, and lobby for the spectrum required for critical communications to operate effectively.

The TCCA works closely with organisations responsible for the development of open standards relating to critical mobile communications, including ETSI and 3GPP.


Members of TCCA design, manufacture, build, implement, utilise, analyse, promote, develop and deploy critical communications worldwide.
