Bluetooth is a standard for short range, low power, low cost wireless communication that uses radio technology. Bluetooth is an open wireless protocol for exchanging data over short distances from fixed and mobile devices, creating personal area networks (PANs). The Bluetooth functions by forming piconets and transferring data over the link protocols. It can connect several devices, overcoming problems of synchronization. Bluetooth network can support mobility and flexibility of nodes in a network. Bluetooth is one of the most widely used wireless technology.Although originally envisioned as a cable-replacement technology by Ericsson (a major cell phone manufacturer) in 1994, embedded Bluetooth capability is becoming widespread in numerous types of devices. They include intelligent devices (PDAs, cell phones, PCs), data peripherals (mice, keyboards, joysticks, cameras, digital pens, printers, LAN access points), audio peripherals (headsets, speakers, stereo receivers),and embedded applications (automobile power locks, grocery store updates, industrial systems, MIDI musical instruments).Joint work by the SIG members allowed the Bluetooth vision to evolve into open standards to ensure rapid acceptance and compatibility in the marketplace.In recent times, Bluetooth has emerged as a reliable technology for transfer of data over short distances. Various versions of Bluetooth have been developed with each delivering better performances than the previous one. The Bluetooth technology competes well against other wireless technologies that are used nowadays like Wi-Fi, Infra-Red, Wi-MAX, Ultra Wide Band etc. Bluetooth is and will continue to stay as one of the most important and widely used wireless technology because of its features like low cost, low power consumption, robustness and easy implementation.
