Bluetooth technology aims at allowing wireless short-range communications between several devices. Developed originally by Ericsson, Bluetooth undergoes an evolution of its specifications maintained and developed by the Special Lobby Special Interest Group (SIG) of Bluetooth and is accessorily standardized by the IEEE under the reference IEEE 802.15.1. Today IEEE 802.15 subgroups and other forums such as the Wimedia Alliance are competing for the same field of operation.
