Bluetooth piconets coexistence: analytical investigation on the optimal operating conditions

The increasing demand for low cost and efficient short range radio communication tools led to the development of the Bluetooth technology, which is aimed at replacing the wires used to connect electronic devices. It is foreseen that, in the next future, Bluetooth based services will be provided in highly populated environments, such as airports and convention centers. The expected explosive penetration in the mass market of BT equipped devices operating in an uncoordinated way makes the issue of mutual interference a key aspect to be investigated in order to assess the real performance of this emerging technology. In this paper herein, we address the coexistence issue by analytically deriving a lower bound on the aggregated throughput offered by BT based WPANs (wireless personal are networks) deployed in the same region and by evaluating the optimum operating conditions.
