CSI technology gets patent

CSI Wireless Inc has been awarded a patent for its antenna splitter technology for the motor vehicle market. Initially submitted for patent protection

CSI Wireless Inc has been awarded a patent for its antenna splitter technology for the motor vehicle market. Initially submitted for patent protection in early 2000, the AVL-1 antenna signal splitter uses a vehicle's standard AM/FM radio antenna to receive accuracy-enhancing differential GPS (DGPS) signals.

DGPS technology enables users to improve location accuracy to within one to five meters (3.28 to 16.4 feet).

The AVL-1 enables a standard AM/FM antenna to interface with CSI Wireless' 300 kHz beacon differential technology. The splitter effectively inserts itself between the vehicle's antenna and the radio, with a connector to one of CSI Wireless' DGPS receivers. This eliminates the need for additional external DGPS antennas on all vehicles equipped with AM/FM antennas.
