The Official Bluetooth® Technology Web Site. Bluetooth protocols. The Bluetooth protocol stack is split in two parts: a "controller stack" containing the timing critical radio interface, and a "host stack" dealing with high level data.
The controller stack is generally implemented in a low cost silicon device containing the Bluetooth radio and a microprocessor. The host stack is generally implemented as part of an operating system, or as an installable package on top of an operating system. For integrated devices such as Bluetooth headsets, the host stack and controller stack can be run on the same microprocessor to reduce mass production costs; this is known as a hostless system.

Bluetooth wireless technology is different from historical wireless standards in that it is an open standard that is consistent worldwide.
The Bluetooth Special Interest Group (SIG), comprised of leaders in the telecommunications, computing, and network industries, is driving development of the technology and bringing it to market. The Bluetooth SIG includes promoter companies 3Com, Ericsson, IBM, Intel, Lucent, Microsoft, Motorola, Nokia and Toshiba, and more than 2000 adopter companies. The goal of the SIG is to promote the standard, ensure interoperability, define the radio characteristics, link protocols and profiles, and provide free access to the Bluetooth standard. The benefits to producers include standardized connectivity and protocols, opportunities for product enhancement and differentiation, and reduced interoperability concerns. Broadcom is an associate member of the Bluetooth SIG and participates in various Bluetooth SIG working groups.
