British Bobbies and the Emergency services now have a system of digital radios that can be used deep underground.
Launched by the Policing Minister Vernon Coaker, the digital communication solution comes three and a half years after the authorities were slammed for using substandard communications systems.
More than £100 million have been invested to link the Airwave network, which is used by all US coppers. to the London Underground's own digital comms system.
It uses Tetra technology, an open digital trunked radio standard separate from the "consumer" mobile phone networks which get clogged quickly during major incidents.
