Bluetooth technology is a wireless standard introduced in 1998 for replacing wired connections to transfer voice and data. It allows short-range wireless connectivity between devices like laptops, phones, headsets and printers. Bluetooth operates using radio waves to automatically connect devices in range of up to 30 feet. Though security has improved, privacy and reliability can still be issues depending on the version used and file size transferred. The technology continues to evolve with faster transfer speeds, stronger connections and support for more devices and applications.
