CRITICAL COMMUNICATIONS
ISSUE 03 2014
to influence politicians, regulators, budget holders and other decision- makers by making the socio- economic case for developing and delivering mobile broadband services for critical users. A further publication covers the range of implementation and delivery options for CCMB, developing the arguments for and against the various approaches.
Do critical communications users need broadband? What happened to TEDS?
TEDS is capable of delivering wideband services, but not the truly broadband speeds that certain critical applications, for example live high-definition multicast streaming video, will demand. However it is notable that in the last few weeks, Norway has demonstrated the capabilities of TEDS over its Nødnett dedicated public safety network. Tor Helge Lyngstøl, director general of the Norwegian Directorate for Emergency
from independent sources such as WIK Consult and the London School of Economics are adding considerable weight to our lobbying work, and we are hopeful of a positive outcome in terms of spectrum allocation from the World Radio Conference in 2015 (WRC-15).

Communication, is quoted as saying: “Nødnett data services will enable users to report in real-time from accident scenes, stream video and share images. We have a responsibility to provide a proper mission-critical data service for our people and that’s what we are moving to do now with the TEDS network. We are impressed with the capability of TEDS to support concurrent data streams and support critical data applications that end users need to be more effective and better safeguard themselves and the public.”
Many critical applications can operate over TEDS, with the proven features of resilience, security and guaranteed service levels that critical users need. The CCBG is working to ensure that LTE networks engender the same confidence, once the critical broadband features have been standardised in the future.

What about spectrum – is the CCBG active in securing spectrum for critical communications broadband services? Spectrum is key to the future of dedicated critical communications services. We have appointed a dedicated spectrum director, Jeppe Jepsen, who is responsible for driving the spectrum agenda, in particular for European Public Protection and Disaster Response (PPDR) applications of CCMB.

However, we are fighting economics: the belief that competition can solve everything, and that commercial network operators are willing and able to provide truly mission critical communications capabilities. If governments choose commercial operators to deliver critical communications services, we can only hope that the networks are upgraded sufficiently to support the very specific resilience, reliability, coverage, capacity and availability needs of the emergency services.
What of the future – what’s on your agenda for the next two years? Each Working Group has defined further goals and deliverables for the next phases of their work. For example the SC group will be expanding the Strategic Case document to encompass transportation, utilities and other critical users, as well as PPDR. The UR and SA groups are working closely together on aspects of security and resilience requirements for critical mobile broadband services over an LTE bearer, and so on. Plus of course we will continue to work to secure protected spectrum for critical communications users. LTE
