Bluetooth/GPS system

Friday, 05 August, 2005 | Supplied by:

RF Micro Devices has released the RF8900, claimed to be the industry's first sole-source 'converged' Bluetooth GPS solution.

Through its ability to integrate both Bluetooth communication and GPS technology into a complete system, the device enables a 20% reduction in size and a 25% reduction in cost, versus competitive solutions.

The device is the enabling technology for 'puck-style' devices that transmit location information wirelessly, enabling location-based services to be received by any handheld device with Bluetooth and associated mapping software.

The RF8900 includes a processor that performs both the GPS navigation and Bluetooth communication functions. In addition, it includes all system integration functions customised for high-volume applications.

The device is an integrated system incorporating Bluetooth and GPS navigation with signal sensitivity (-155 dBm). The signal sensitivity of the RF8900 is 5 dBm, enabling it to track GPS signals down to -155 dBm, while maintaining a one-second position update rate. High signal sensitivity allows the end user to locate their position virtually anywhere, including areas where GPS signals are weak, fading or obstructed, such as indoors and outdoors where there is foliage, tall buildings or mountains.

The system comes with a reference design that includes all required software, filtering, memory, reference frequencies and antennas. It is designed to interface with Bluetooth-enabled PDAs, mobile phones and personal computers.
