The TETRA and Critical Communications Association has become the latest Market Representation Partner within 3GPP, the organisation responsible for the development of mobile wireless standards. LTE is set to offer increased interoperability between critical communications systems and ubiquitous networks based on 3GPP specifications, without compromising on the highest standards necessary for the secure operation of mission critical voice and data services. Several new features are being worked on in 3GPP, which has led to a high degree of participation from public safety groups.

At the detailed level, the TCCA’s Critical Communications Broadband Group will work closely with 3GPP, on Spectrum, Architecture, User requirements and on strategic case studies. The TCCA has set out a plan for its members service evolution, for data and voice for LTE, with four sequential steps identified:

1. Upgrade existing Mission Critical V+D services until LTE readiness and maturity
2. Uptake of Non Mission Critical data with commercial LTE
3. Build Mission Critical Data LTE networks
4. Migrate Mission Critical Voice

In his proposal to 3GPP, Phil Kidner, the TCCA Chief Executive promised that “The Association will bring a European and global input to 3GPP for critical communications”. The formal signing of the 3GPP Partnership Agreement will take place at the next meeting of the Partners, in Fukuoka, Japan on the 30th October.
