In the event of a natural disaster or terrorist threat how would we communicate?
How does your business ensure that all critical communications will be transmitted?
Businesses and individual are reliant on communications hosted by a third party telephone network such as O2, Vodafone and Three but what would happen if these services were not available?
Businesses and public services need to be able to communicate, if the third party services stop, this is where critical communications are vital.
As it stands, emergency communications are run on a private network called Airwave. This network is supplied to the Scottish Fire & Rescue Service, as with counterparts across Great Britain, known as FireLink.
This network is run on TETRA technology.
What is TETRA?
Terrestrial Trunked Radio; it is a set of standards developed by the European Telecommunications Standardisation Institute (ETSI) that describes a common mobile radio communications infrastructure throughout Europe.
Blue light services such as Police, Fire and ambulance along with other bodies serving the public such as utility companies, use the TETRA network. TETRA gives fast and accurate field communications to and from a central office or dispatcher, which are are often critical.
TETRA relies on digital trunking. TETRA-based products come with built-in encryption features to ensure the privacy and confidentiality of sensitive data/voice communications. These products are also designed with the ability to transfer data at faster rates than seen before in mobile communications.
“The ability to communicate – whether by voice or data – is vital for the proper functioning of our Blue Light Emergency Services (police, fire and ambulance services) and other Category 1 Responders (e.g. health boards and local authorities)” Scottish Government
Is there a solution for non-blue light companies?
Short answer ‘yes’
Radio systems come in varying sizes and functionality:
Radio to radio system: If your business is based in one place i.e. Farm land, large yard, stadium etc. providing the distance between each hand portable radio is not vast, the radios can be set up with this hardware only. The radio’s would be programmed to a private channel which eliminates the chance of interference and increases privacy.
Private channels require a radio licence. The cost of the licence is relative to the size of the coverage area and business use.
