Chapter 1. What Is Bluetooth?

The term Bluetooth™^[1] refers to an open specification for a technology to enable short-range wireless voice and data communications anywhere in the world. This simple and straightforward description of the Bluetooth technology^[2] includes several points that are key to its understanding:

^[1] Bluetooth is a trademark owned by Telefonaktiebolaget L M Ericsson, Sweden and licensed to promoters and adopters of the Bluetooth Special Interest Group.

^[2] The Bluetooth Brand Book contains guidelines for the use of the term Bluetooth. To be consistent with those guidelines, we will henceforth use the term as an adjective, not as a standalone noun.

Open specification: The Bluetooth Special Interest Group (SIG) has produced a specification for Bluetooth wireless communication that is publicly available and royalty free. To help foster widespread acceptance of the technology, a truly open specification has been a fundamental objective of the SIG since its formation.
