Critical Communications Broadband Group

TCCA's Critical Communications Broadband Group (CCBG), a Working Group of TCCA, drives the development and adoption of common global mobile broadband standards and solutions for users who operate in a mission critical or business critical environment*.

The aim of the CCBG is to enable all mission critical and business critical users to access their information systems, intranet and internet at broadband speeds using their professional mobile devices wherever they are and whenever they have the need. This broadband capability should meet the specific needs of the user in the same way that critical voice and narrowband data services are currently delivered by technologies such as TETRA, Tetrapol, P25 and others.

*Examples of mission critical and business critical users include the following:

  • Public Safety/PPDR
  • Government entities
  • Utilities (Electricity, Gas, Water)
  • Power Generation
  • Petrochemical/Extraction
  • Transport (International and Metropolitan Rail, Metro, Ports, Airports, Buses, Trams and Taxis)
  • Military/Paramilitary
  • Security
  • Telcos
  • Sporting and leisure complexes
