That’s according to ABI Research, which said that existing safety protocols like TETRA and P25 are well established because they are so stable.
But LTE vendors are working with both TETRA and P25 vendors to introduce LTE (4G) capabilities.
ABI said that since Release 10, 3GPP has included enhancements which improve the mission critical features of LTE.
LTE-Relay extends network coverage while LTE-Direct lets public safety devices create direct point-to-point communication without needing a base station.
Release 13 of 3GPP will standardise indoor positioning and push to talk capabilities.
A number of vendors is working together to show the advantages of a single unified broadband and narrowband system, with Motorola, Ericsson, Harris and Nokia working together.
ABI believes that the first markets to have a fully working public safety network will be the USA, the UK and South Korea.
