The embedded world Exhibition & Conference is the world’s premier event on the embedded systems topic. It brings together researchers and developers, industry and academia from all disciplines of embedded system development and drives the development of complex systems of systems and its manifold innovative aspects.
The embedded world Conference in collaboration with Bluetooth SIG will hold a special Bluetooth® technology session at the show:
Presenter: Damon Barnes, Bluetooth SIG
Date and Time: 8 October, 11:00-11:30am CST
Description: With over 5 billion devices shipping each year, Bluetooth technology is the most widely deployed wireless standard in the world. ABI Research predicts 7.5 billion Bluetooth devices will ship in 2028, representing an eight percent compound annual growth rate (CAGR) over the next five years. A number of recent technology enhancements and upcoming features will help Bluetooth maintain its dominant position in the wireless communications industry over the coming years. In this presentation, Damon Barnes, Director of Technical Marketing at the Bluetooth SIG, will provide an update on key Bluetooth technology trends, Bluetooth Channel Sounding, and key upcoming feature projects, including High Data Throughput, HID (human-interface device) feature enhancements, and Higher Frequency Bands (5/6 GHz).
Presenter: Dr. Avik Santra, Infineon Technologies
Date and Time: 8 October, 11:30am-12:00pm CST
Description: Bluetooth Channel Sounding is a positioning feature for fine ranging that allows estimating the distance between connected devices through precise and secure measurements. Depending on design capabilities, environment conditions, and the distance estimation algorithm chosen, the accuracy of Bluetooth Channel Sounding can be as good as 0.25 m at short distances and sub-meter for longer distances, which is adequate for the needs of applications like car access, home automation, asset tracking, and location-based services. Bluetooth Channel Sounding is a powerful feature setting a clear and solid foundation for standardized and efficient ranging. Purposefully, the Bluetooth SIG makes no recommendations for the selection or implementation of distance estimation algorithms in order to provide developers the flexibility to pick a solution optimized for their use case, with the implicit tradeoffs in performance, computational requirements, and measurement speed. In this presentation, we dive into the topic of distance estimation algorithms for Bluetooth Channel Sounding. First, we provide a high-level overview of algorithms available and how they work. Then, we discuss some of the parameters and variables that impact their performance. Next, we present experimental results for a suite of algorithms implemented by Infineon in hardware and characterized by their accuracy, robustness, and computational efficiency. Finally, we talk briefly about algorithms suitable for scenarios with multiple Bluetooth devices present, summarizing their advantages and limitations in various scenarios, and discussing how can they combine to achieve higher accuracy and robustness for distance estimation.
Presenter: Hendrik Cordier, Qualcomm
Date and Time: 8 October, 12:00-12:30pm CST
Description: Auracast broadcast audio technology will revolutionize how we experience audio. With a rich heritage in Bluetooth and connectivity Qualcomm technologies has worked closely with the Bluetooth SIG on the Auracast broadcast audio profile, and the technology is now supported across Qualcomm’s extensive portfolio. We are now able to bring very simple transmitter devices to public locations, in addition to building support into a variety of Bluetooth hearable devices such as earbuds, headphones and speakers, along with new assistive listening or cross-over devices. This interactive session will provide a practical demonstration, weaving in examples and results from real-life events, to showcase how easy it is to use the Qualcomm S7, S5 and S3 Sound Platforms for the development of transmitters, receivers, and broadcast assistants. It builds upon the ‘Auracast Simple Transmitter Best Practices Guide’, introducing mechanisms for straightforward commissioning of Auracast broadcasters for public venues. The session will also demonstrate how to discover and receive Auracast broadcasts on your hearable audio device with the use of a simple smartphone applications, enabling wider deployment than otherwise possible. Qualcomm branded products are products of Qualcomm Technologies, Inc. and/or its subsidiaries.
