Bluetooth technology was introduced in 1998 as a wireless replacement for wired connections to transfer voice and data rapidly between devices over short distances. It allows for automatic recognition and connection of devices like laptops, phones, headsets and printers. While Bluetooth provides convenient wireless connectivity with low power usage, it has some limitations regarding security, file size and distance between devices. Ongoing development by the Bluetooth Special Interest Group aims to increase transfer speeds, connection strength and operating distances for Bluetooth over time.
