Overview

The Emergency Services Network (ESN) will be the new communication system used by the three emergency services and other public safety users across the United Kingdom.

The service will become an essential part of Britain’s critical national infrastructure. It will give the EmergencyServices the latest technology, delivering secure, resilient voice communications and high speed data services.

Installation Technology has been asked to investigate the feasibility of using LTE in underground stations and tunnels through the testing of off the shelf cellular technology.
