- Aimed At
-
Those who are developing or implementing high-performance wireless systems will benefit from the detailed analysis of the Bluetooth specification, including range calculations, modulation and packet structures, and how Bluetooth devices find each other and establish a communication link between them. Designers will gain insight into how device authentication, encryption, and other security measures are implemented in Bluetooth, and how a Bluetooth device communicates with its host. The strengths and weaknesses of Bluetooth against other wireless network protocols, and the interference they cause to each other, will be especially useful to those who must select one or more wireless methods best suited to their specific applications.

None
- Course in a Nutshell
-
This comprehensive three-day course introduces and analyzes Bluetooth wireless networking based on Bluetooth specification 2.1 + EDR (Enhanced Data Rate).
Participants begin by studying Bluetooth signal propagation characteristics, modulation, packet structure, data and audio processing, and error control. The role of the Bluetooth link manager in establishing a connection and implementing security and encryption measures is then discussed. Various higher layers in the Bluetooth protocol stack are examined such as packet segmentation and reassembly, service discovery, the host controller interface, and the implementation of application profiles. The Bluetooth qualification program is discussed. Finally, the ability of Bluetooth to coexist with other wireless networks in the 2.4 GHz band is analyzed.
- Customize It!
