The Australasian Critical Communications Forum (ACCF), is a chapter of The international Critical Communications Association (TCCA) with more than 150 members from around of the globe bringing together stakeholders with an interest in the development, deployment and use of open standard non-proprietary critical digital wireless communications. ACCF/TCCA members promote and design, manufacture, build, integrate, implement, analyse, utilise and deploy standardised critical communications worldwide. The TCCA works closely with international standardisation bodies such as ETSI, the European Telecommunications Standards Institute, and the 3rd Generation Partnership Project (3GPP) responsible for the development of international standards relating to critical mobile communications and broadband technologies including 5G and is a partner in the international Mission Critical Open Platform project (MCOP).
