The Home Office is a ministerial department of the British Government, responsible for immigration, security, and law and order. We’re currently leading the Emergency Services Mobile Communications Programme (ESMCP) to deliver the new Emergency Services Network (ESN) critical communications system. ESN will enable fast, safe and secure voice, video and data across a 4G network and give over 300,000 first responders immediate access to life-saving data, images and information in live situations and emergencies on the frontline.
