TCCA Working Groups are set up and managed by TCCA members, and report to the Association Chief Executive and Board.
The Asia Regional Group encompasses North Asia (Japan, Korea, Greater China), South-East Asia (ASEAN) and South Asia (India, Sri Lanka, Bangladesh). The Group works to understand the landscape in respect to business and mission-critical communications in each of the nations within the region.
The Broadband Industry Group (BIG) facilitates 3GPP mobile broadband vendor cooperation and collaboration for the benefit of customers, focused on the development and promotion of global critical communications solutions that are built using 3GPP 4G LTE, 5G and 6G standardised technologies.
The CCBG drives the development and adoption of common global mobile broadband standards and solutions for users who cooperate in a mission critical or business critical environment, working closely with industry and public safety stakeholders.
This Group primarily considers emerging technologies, or novel use cases of existing or emerging technologies, that are of potential interest to the community served by TCCA, providing an early forum for horizon-scanning and technical assessment.
At the crossroads of moving from LMR systems like TETRA, P25 and GSM-R to the broadband 3GPP world, an interface is needed to ease transition between heterogeneous systems. The IWF Working Group identifies and develops these interworking functions.
TCCA's Legal and Regulatory Working Group (LRWG) focuses on the legal and regulatory issues and challenges related to the evolution from TETRA to broadband services for critical communications. The LRWG is open to governmental operators of critical communications networks.
The SFPG prepares and manages recommendations on the use of security in critical communications networks, and supports members in addressing emerging security and fraud risks facing the sector.
The Spectrum Group is guided by the principles of harmonisation and efficient spectrum use to meet the needs of critical communication users, agreeing common positions on spectrum matters that secure narrowband PMR technologies and support evolving broadband communications.
Among other responsibilities, this group converts the service overviews into profile and test documents which will be used for the Interoperability Testing and Certification process (IOP), and provides a key forum for knowledge exchange.
TETRA Industry Group (TIG) works to promote TETRA, develop the technology and advocate an evolutionary path towards future solutions for the mission critical communications market TETRA serves, based on open standards, drawing on the complementary strengths of TETRA and LTE.
