The Institute of Electrical and Electronic Engineers, an international body that sets the standards for a range of electrical and electronic systems, officially approved the BlueTooth compatible 802.15.1 standard for Wireless Personal Area Networks.
Bluetooth was conceived as short-range wireless technology designed as a replacement for cables and wires between devices. The 802.15.1 standard was developed by a subcommittee of the IEEE’s broader 802 Standards Committee, which also developed the 802.11 Wireless Ethernet standards. Since some 802.11 implementations and BlueTooth occupy the same frequency range, part of the 802.15 standard deals with how the two share it. Other parts of the standard deal with how network interactions can be done over a BlueTooth connection and how a BlueTooth network might interact with a wireless or wired network.
With the standard set, it allows hardware manufacturers to support it in their BlueTooth enabled equipment, BlueTooth access points, and gateway hardware, ultimately allowing interoperability between components from different manufacturers.
