Bluetooth
Bluetooth is a wireless technology standard for
exchanging data over short distances (using short-wavelength radio transmission
in the ISM band from 2400 – 2480 MHz) form 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 18,00 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was standardized as IEEE 802.15.1, but the standard is no longer maintained.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 protect the trademarks. To be marketed as a
Bluetooth device, it must be qualified to standards defined by the SIG. A
network of patents is required to implement the technology, which is licensed
only for that qualifying device.
