摘 要：Bluetooth is an open standard for short-range radio frequency (RF) communication. Bluetooth technology, which is used primarily to establish wireless personal area networks (WPANs), has been integrated into many types of business and consumer devices; examples include cell phones, laptops, automobiles, medical devices, printers, keyboards, computer mouse devices, and headsets. Bluetooth technology enables users to establish ad hoc networks supporting voice and data communications between a wide variety of devices that can be conveniently interconnected without the need for cables or wired connections.
