Finnish State Security Networks shows how to succesfull migrate from TETRA to LTE
High speed data will bring so many benefits to public safety users that it’s not surprising everyone wants to introduce it and as quickly as possible. But how is it done? What are the steps on the path to broadband? And who is doing it right now?
According to Airbus Defence and Space, there is a good answer to the last question. Finland’s VIRVE nationwide network operator State Security Networks has started on a step-by-step plan to bring high speed data to its users via a hybrid network built on TETRA and LTE. And they are not hanging around. The first step was setting up a mobile virtual network operator (MVNO). Its first customers received SIM cards for the network in January 2016.
The benefits are obvious. With the state-operated VIRVE network behind it, users are assured that they are getting a secure data service. Plus, there’s the added reliability of two networks - one commercial operator on the normal LTE frequency bands and one on the less common 450 MHz band – so getting connected will not be a problem.
Users also have a choice of which device to use to access the network – from PDAs to laptops, everything is supported.
With step one ticked off, VIRVE is already planning for step two. This will see critical voice and messages run in the narrowband network, with high-speed non-critical (but secure) data running in the commercial broadband network.
When broadband services develop the required features as well as the required reliability and security, the different services can then be merged.
VIRVE is certainly setting the pace in showing how TETRA network users can adopt broadband successfully.
Supplier of the VIRVE network, Airbus Defence and Space created a document "Finland - Hybrid networks in use. Hybrid network covers mobile broadband needs of mission critical users" gives more information about VIRVE’s approach.
