UK based Mobile phone tracking company Trace A Mobile.com today announced it was now using an advanced software system called Timing Advanced mobile phone tracking (TA) to allow improved phone tracking accuracy of up to 50 metre range for the Vodafone network. The technology measures the timing and power of GSM mobile phone signals from 3 or more base stations to increase its Location Based Services (LBS) accuracy by up to 300 per cent.

Explaining the new system Managing Director Jonathan Cook said, "The timing of the bursts transmissions is very important to track mobile phones. Mobiles are at different distances from the base stations. Their delay depends, consequently, on their distance. The aim of Timing Advance is that the mobile trace signals coming from the different mobile stations arrive at the base station at the right time so it can locate a mobile much more accurately."

Other new LBS technology also planned by the company is Assisted GPS. Arriving soon in the United Kingdom these new mobile phones will include a global positioning receiver and promise an accuracy of up to 10 metres for phone locating.

Since launching in 2003, Trace A Mobile’s other mobile tracing product innovations have been the ability to receive a tracking request via SMS and the widening of coverage to include Northern Ireland. Summing up the last twelve months Jonathan adds, "We have managed to develop and lower our cost for tracking searches.
