Scenario driven evaluation and interference mitigation proposals for Bluetooth and high data rate Bluetooth enabled consumer electronic devices

This paper investigates the effects of interference occurring between Bluetooth and high data rate Bluetooth enabled consumer electronic devices in the home and office environment. Software simulated results for frequency collisions between piconets operating in both synchronous and asynchronous modes with typical up and downlink loading factors are presented (for time-bounded and non-time bounded electronic devices). The significance of this interference on the data throughput in a number of example scenarios is investigated using a state-of-the-art indoor space-time propagation model. These results are then compared with measured channel data taken in the test environment using a MEDAV RUSK BRI channel sounder. The paper concludes by proposing to mitigate the effects of interference by employing synchronous communication in future Bluetooth and Bluetooth evolution networks.
