Bluetooth

Bluetooth is a wireless technology standard for exchanging data over short distances (using short-wavelength radiotransmissions in the ISM band from 2400–2480 MHz) from fixed and mobile devices, creating personal area networks (PANs) with high levels of security. Created by telecom vendor Ericsson in 1994, it was originally conceived as a wireless alternative to RS-232 data cables. It can connect several devices, overcoming problems of synchronization.

Bluetooth is managed by the Bluetooth Special Interest Group, which has more than 18,000 member companies in the areas of telecommunication, computing, networking, and consumer electronics.

Bluetooth was standardized as IEEE 802.15.1, but the standard is no longer maintained. The SIG oversees the development of the specification, manages the qualification program, and protects the trademarks.^[4] To be marketed as a Bluetooth device, it must be qualified to standards defined by the SIG.^{[citation needed]} A network of patents is required to implement the technology and are licensed only for those qualifying devices.
