LEADING telecommunications firms BT and Motorola have joined forces with the police to develop a hi-tech new radio system that is set to hit Blackpool next month.

The "Airwave" service, launched in Preston this week, is the first step in plans to equip officers with a "virtual office" that can be carried around in a car or even clipped to a belt and which will give access all the information on the force's computer systems.

At this stage, though, the new system will increase coverage, give full encryption and allow officers to make calls directly to standard mobile phones, with plans to extend facilities over the next few months to include text messaging, touch screens and vehicle tracking capabilities.

Chief Supt Bernard Lawson said: "The fact is, officers can't wait to get their hands on these new radios. Our staff know this will really help them to fight crime effectively."

But, concerns have been raised over the possibility of digital radio transmissions interfering with sensitive hospital, speed enforcement and breathalyser equipment, as well as the familiar health concerns.

Director of Corporate Services, David Brindle said that, having tested most equipment, it had been declared safe from interference. Concerning health issues, he added: "I am confident there is nothing to fear".
