Modelling for Bluetooth PAN reliability
Xiao Xiong, JK Pollard · 2005
redundant links, sensors. Bluetooth-enabled sensors may be used for monitoring personal health but there is considerable interference in the received signal due to multi-path reflections. It is important that communication reliability should be improved in safety-critical data-acquisition applications. A new topology of the Bluetooth radio system is presented using cloned transmitting devices to enhance signals in particular directions. The multi-path interference at the receiver was reduced and this enabled improved signal quality (lower Bit Error Rates) to be achieved. Computer modelling was conducted to evaluate the magnitude of improvement by using Space/Time/Frequency redundancy in indoor wireless communications.
