Next-Generation Bluetooth 6 and Beyond

Bluetooth is a cable replacement technology for short-range data exchange and has become indispensable for smartphone chipsets, hands-free calls, in-vehicle infotainment, fitness bands, hearing aids, and wireless ear buds. Bluetooth devices communicate with each other in a limited area to form a small network. The Bluetooth consumer market is driven by over 1 billion wireless audio accessories that are sold annually, including ear buds, gaming headsets, and smart speakers. The ubiquity and quality of Bluetooth voice communications and audio streaming will be further enhanced with LE audio and the use of advanced codecs such as LC3.

Using over 330 informative slides, this course describes the foundational principles of Bluetooth, including the latest technologies and applications. More specifically, it discusses the technical details of the Core Specification 6.2 and new use cases such as location and positioning services, distance measurement, and multi-stream audio streaming and sharing. Bluetooth LE audio and real-time isochronous stream support are covered, including subrated connections and flow control in telephony and audio applications. The course also presents key Bluetooth physical and medium access layer mechanisms, as well as detailed packet formats that illustrate the functions of each mechanism. A coherent analysis of channel sounding and enhanced security is described. Practical tips on Bluetooth audio codecs, Android Bluetooth, Radio Interface Layer (RIL), Hardware Adaptation Layer (HAL), and Qualcomm MSM Interface (QMI) are also provided, together with a short quiz.

The instructor has published 15 wireless books and over 70 scientific research papers. Four of his books were used as training material for Anthropic and other AI companies. He has taught custom Bluetooth courses for Qualcomm and Motorola Solutions, and has served as an expert witness.
