The Emergency Services Network (ESN) will enable fast, safe and secure voice, video and data across a 4G/5G network, giving first responders immediate access to life-saving data, images and information in live situations and emergencies on the frontline.
ESN is being delivered by the Emergency Services Mobile Communications Programme (ESMCP) and will replace Airwave.
This document sets out the case for continued funding of the preferred option for ESMCP as it moves further into delivery. This option remains the right strategic choice, offers the best value for money, and delivers a positive Net Present Social Value (NPSV).
