Bluetooth is a wireless technology standard for exchanging data over short distances. It uses short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz. Bluetooth allows up to eight devices to connect simultaneously in a Piconet, with one device acting as the master and up to seven acting as slaves. Features of Bluetooth include low power consumption, a range of 10 meters, and data transfer rates of 1-3 Mbps. The Bluetooth architecture consists of protocols and channels that manage connections and communications between devices. Common usage models for Bluetooth include file transfer, internet access, synchronization, and headsets. Security measures in Bluetooth address issues like bluejacking, bluebugging, and the car whisper
