Cambridge Positioning Systems (CPS) has secured a new patent in the USA for its Matrix high accuracy location technology.

Cambridge Positioning Systems (CPS) has secured a new patent in the USA for its Matrix high accuracy location technology.

The patent - 'Improvement in Radio Positioning Systems' - is the tenth that CPS has been granted in North America and further strengthens and enhances the company's IPR portfolio that now extends to more than 24 patent families worldwide.

Matrix technology, which makes use of the signals radiated by the cell towers to locate the position of a mobile phone, underpins all the company's positioning technology.

This includes the recently announced E-GPS system, which combines Matrix and GPS technology to deliver powerful all-environment coverage, lower implementation costs and fast location fixes for wireless devices.

CPS CEO Chris Wade said: "Our strategy has always been to develop and protect our IPR strengths while at the same time ensuring that we enable widespread market take-up through fair and competitive licensing arrangements".

"The growing list of major vendors and new market players embracing Matrix technologies shows that this is the way to drive the location based services market forward".

CPS's policy is to apply for patents worldwide which protect its core intellectual property.

These include both in technologically advanced nations and countries such as China - where CPS recently announced its first patent award - that are emerging as major powers in the mobile communications industry.

CPS delivers cost competitive high accuracy mobile location technology to the billion-strong customer GSM and emerging 3G/W-CDMA markets.
