TUTORIAL III
The Bluetooth Technology: Specifications and Performance
Rajeev Shorey and Apurva Kumar
IBM India Research Laboratory

Audience: This tutorial is intended for computer professionals, telecommunication engineers, researchers, educators, and graduate students interested in the Bluetooth technology.

Course Description: Bluetooth technology provides a low cost, low power, and low complexity solution for ad-hoc wireless connectivity. The technology is capable of connecting a wide variety of devices like Personal Digital Assistants (PDAs), mobile and cordless phones, headsets, desktops and notebook PCs, digital cameras, home appliances, etc. The applications include eliminating cables/ wires between devices like PCs, printers, modems, projectors, self synchronization between PDAs and PCs, wireless connection to local area networks (LANs) through access points and internet through mobile phones, providing home networking solutions, etc. This tutorial will provide an overview of Bluetooth technology and its applications. The Bluetooth system will be introduced and various modes of operation will be discussed. A description of functionalities of Bluetooth layers and the protocol specifications will be presented. Various usage scenarios and the profiles which support them will be explained. An insight into the performance of Bluetooth based systems will be provided. Means of evaluating/improving performance of Bluetooth based systems will be discussed. Key features of an open-source Bluetooth simulation tool which can be used to evaluate the performance of applications over Bluetooth will be described. We will provide an overview of a number of open research problems related to Bluetooth specifically, and short range wireless in general. Some of the problems that we will discuss are MAC scheduling with and without low power modes, performance of TCP/UDP over a Bluetooth piconet and Bluetooth capacity.
