Bluetooth is a proprietary wireless technology intended for short-range communication that is overseen by the Bluetooth Special Interest Group. It provides a secure, robust, low power, and low cost method for exchanging information between devices. Because it is a global standard, any Bluetooth-enabled device can communicate, or pair, with any other. A Bluetooth device can also connect with up to seven other devices in an ad-hoc personal-area network called a piconet, and be a member of several piconets at the same time. Bluetooth uses a technology called frequency-hopping to ensure that it is resilient against interference. Bluetooth utilizes frequency-hopping spread spectrum technology to avoid interference problems. The ISM 2.4 GHz band is 2400 to 2483.5 MHz, and Bluetooth uses 79 radio frequency channels in this band, starting at 2402 MHz and continuing every 1 MHz. It is these frequency channels that Bluetooth technology is hopping over.
