By the end of 2004 , the majority of the existing police radio spectrum , which was subject to serious interference in some areas , was to be withdrawn and replaced by a new spectrum of superior quality , dedicated to use by public safety organisations , on which users would be required to use digital equipment . Knowledge of this change reinforced the need , already identified by the Association of Chief Police Officers ( ACPO ) and the Home Office , for a new radio strategy . A Review of Radio Communications in the Police and Fire Services of England and Wales was inaugurated , a parallel review was carried out in Scotland , and the Public Safety Radio Communications Project was born . The radios proved exceptional during the 2005 London bombings
