ESN (Emergency Services Network)

ESN is the Government’s selected option to replace the Airwave Network, which The Emergency Service in England, Scotland and Wales use for communications between Control Rooms and the ‘Field’.

ESN will enable fast, safe and secure voice, video and data across the 4G network and give first responders immediate access to life-saving data, images and information in live situations and emergencies on the frontline.

Investment in ESN will also mean improvements to 4G network coverage, which will allow 999 calls to be made from any 4G enabled mobile phone in some of the most remote and rural parts of Great Britain where it was not previously possible.
