Cambridge Positioning Systems (CPS) has secured its first success at the Chinese Patent Office for its Matrix location technology. With Matrix, mobile devices may be located to sub-100m accuracy across all environments in systems using GSM, W-CDMA and China's own 3G technology TD-SCDMA. China, with over 360 million mobile users, represents one of CPS's main markets with growing demand for high accuracy solutions to meet a burgeoning market for vehicle, asset and personnel safety tracking. CPS's policy is to apply for patents worldwide which protect its core intellectual property, and today it has more than twenty patent families relating to positioning systems.
