How Bluetooth works

Bluetooth technology operates on the principle of short-range radio communication using low-power radio waves in the 2.4 to 2.485 GHz frequency band. Devices equipped with Bluetooth contain a tiny radio transmitter and receiver that enable them to communicate wirelessly. When two Bluetooth-enabled devices come within range, they establish a connection by performing a process called "pairing." During pairing, the devices exchange unique identification codes and create a secure link. Data transmission between paired devices occurs through a series of short-range radio frequency hops, where the transmitting device breaks data into packets and sends them out on different frequencies within the designated band. The receiving device collects and reassembles these packets in the correct order to reconstruct the original data. Bluetooth technology allows for the seamless transfer of data, enabling devices to communicate and share information efficiently within a short range without t...
