Essentially this comprises hardware and software. The hardware is the SiRFStarV chipset, and the software is SiRFusion. The SiRFStarV architecture has been designed to 'sniff' a number of different radio signals from WiFi to Bluetooth, Cell to GPS, incorporating all the different flavours of GPS: NAVSTAR, GLONASS, Galileo, etc. Not only does it detect radio signals but it also has integrated movement sensors. These take over when the traditional radio signals are weak or non-existent. One of the sensors is a pressure sensor, which is so accurate it is able to determine the floor that you are on in a multi story shopping mall. SiRFusion is a software component that allows the various radio signals and sensors to amalgamated, prioritised and fed into a backend server that is able to consolidate all the data and provide a very accurate location either indoors or outside. This software is able to provide realistic locations and discard any invalid data. The self-learning location platform “fuses” location information from multiple technologies to make extremely reliable and accurate indoor location and navigation a reality. The whole package has been designed with mobile in mind paying particular attention to the limitations of power and size.
On the patent front, CSR will transfer 21 U.S. patents to Samsung.
