Bluetooth is a short range wireless interface that offers data transmission rates of the order of 721 kbit/s which is comparable with ADSL data rates, but which could be regarded as being too low for deployment as a limited range wireless access point. The capacity of a wireless access point based on Bluetooth technology can be increased significantly by co-locating a number of Bluetooth transducers in a hotspot scenario. This paper describes a technique which reduces mutual interference in co-located Bluetooth transducers by coordinating the hopping frequencies of the individual devices. Such a system can then provide attractive data transmission rates when deployed in wireless access point applications.
