Summary:In 1998, five major companies (Ericsson, Nokia, IBM, Toshiba and
Intel) formed a group to create a license-free technology for universal
wireless connectivity in the handheld market. The result is Bluetooth, a
technology named after a 10th-Century king who brought warring Viking
tribes under a common rule. The Bluetooth specifications (currently in
version 1.1) define a radiofrequency (RF) wireless communication
interface and the associated set of communication protocols and usage
profiles. The link speed, communication range and transmission power
level for Bluetooth were chosen to support low-cost, power-efficient,
single-chip implementations of the current technology. In fact,
Bluetooth is the first attempt at making a single-chip radio that can
operate in the 2.4-GHz ISM (industrial, scientific and medical) RF band.
While most early Bluetooth solutions are dual-chip, vendors have
recently announced single-chip versions as well. In this overview of the
technology, I first describe the lower layers of the Bluetooth protocol
stack. I also briefly describe its service discovery protocol and,
finally, how the layers of the protocol stack fit together from an
application's point of view
