Critical Broadband

The Critical Communications Broadband Group (CCBG) is a working group of the TCCA tasked with driving the development and adoption of common, 3GPP mobile broadband standards and solutions for users who operate in a mission critical or business critical environment. The CCBG has formed relationships with a wide variety of user and operator groups from around the world that have common aims.
The CCBG’s goals are to enable all Critical Communications users to access their information systems and applications, reliably, and at broadband speeds, on their professional mobile devices, wherever they are and whenever they have the need. This will ensure that critical LMR users have the right tools available to undertake their increasingly complex role and that resources are used in the most efficient manner possible.
The creation of the necessary standards and technology by 3GPP is only part of the solution. Delivering services and products that take advantage of such capabilities in a timely, cost effective and affordable manner is also a significant task.
TCCA has taken the initiative to form a critical communications Broadband Industry Group (BIG), a TCCA Working group formed to encourage broadband vendor cooperation in the development of common global critical commu-nications solutions. The BIG will work closely with TCCA’s Critical Communications Broadband Group (CCBG). These TCCA initiatives will help the co-ordination of critical communications standardisation efforts in 3GPP together with the public safety agencies and operators, in line with the CCBG goals and TCCA’s Market Representation Partner role in 3GPP.

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.

mission critical and business critical users include the following


Oil & Gas


Rail and Metro


Power Generation

Safety/Public PPDR

Government Entities

Ports & Logistics
