4 Editor’s letter
James Atkinson considers some of the
concerns surrounding interoperability in missioncritical
LTE networks, products and solutions
6 Who, what, where
The Netherlands transitions to an upgraded
TETRA network; Highways England invests in
Sepura TETRA radios; Swiss Air-Rescue adopt
Hexagon CAD system; Hamburg re brigades
choose Motorola pagers; Nokia SpaceTime
analytics trialled on Japanese rail crossings;
Klabin implements MOTOTRBO Linked Capacity
Plus system in Brazil
8 News
APD awarded control room integration project by
the Home Of ce for ESN; T-Mobile US and Sprint
merger brings free 5G rst responder offer nearer
9 TCCA news
TCCA has joined a project to create compliance
testing for mission-critical implementations
10 Nordics in focus
PMR is widely used across a number of
industries in the Nordics and each has a
nationwide TETRA emergency services network,
but most are looking towards a broadband future
14 Testing MC 4G products
TCCA’s Jeppe Jepsen explains why it is so
important that an interoperability test and
certi cation process is established for missioncritical
LTE products and solutions
16 3GPP SA6 progress
SA6 chairman Suresh Chitturi provides
an update on the latest work to develop
speci cations for mission-critical applications in
4G and 5G
22 MC LTE in the USA
The USA is implementing a nationwide public
safety broadband network, but the situation is
complicated by other providers offering similar
services, leading to concerns over interoperability
27 Facial recognition
Facial recognition technology can help identify
suspects and locate missing people, but its use
is controversial as it raises privacy concerns
31 Network resilience
PMR networks are hardened to resist
environmental damage and deploy redundant
switches, links and power, but now commercial
4G broadband networks need to nd ways to
ensure they also meet mission-critical criteria
