Rohde & Schwarz announces that the company will showcase measurements on novel Bluetooth Channel Sounding signals for positioning accuracy during the upcoming Embedded World.
The company claims it to be the first real-time measurement of the planned new Bluetooth signals to support Channel Sounding.
Running on an R&S CMW500 wideband radio communication tester, the Bluetooth Channel Sounding feature is said to enable unprecedented positioning accuracy for consumer and commercial applications.
The signal measurement capabilities to support chip and device development which is eagerly awaited by the industry.
The demonstration at the Embedded World Exhibition & Conference in Nuremberg, Germany, will be run on an R&S CMW500 wideband radio communication tester. The Bluetooth® Channel Sounding signals feature will enable unprecedented positioning accuracy for consumer and commercial applications.

What Changes after Bluetooth Meets Channel Sounding
For consumer and commercial devices, Bluetooth is the most widely installed technology with location-determining capabilities. Channel Sounding is known to significantly improve the accuracy of real-time location services. It is said to determine position using Bluetooth to an accuracy of 50 cm or better.
In addition to improved location accuracy, Channel Sounding is expected to consume less power than existing Bluetooth location services and provide increased security.
The improved accuracy will be a major step forward in particular for indoor applications such as asset tracking on the factory floor or in the warehouse, as well as for secure access to buildings or vehicles.
R&S Bluetooth Channel Sounding Signals Measurements Support Chip, Device Developers
Engineers who want to start developing the necessary chips and devices, including support for Channel Sounding urgently require reliable and accurate measurements on the signals that enable the new functions.
Rohde & Schwarz has already prepared options for its R&S CMW platform to support the corresponding RF physical layer measurements. Hardware changes for Bluetooth devices introduced on a new physical layer are required to support the improved location functions.
The current draft of the next version of the Bluetooth Core Specification defines support for phase-based ranging (PBR) tone exchange and round-trip time (RTT).
Early Preview of the PBR Measurement Techniques by R&S at Embedded World
To give hardware and software engineers involved in Bluetooth chipset and device development an early preview of the PBR measurement techniques, Rohde & Schwarz will be presenting a session at the embedded world Conference called “Redefining Bluetooth Low Energy Testing to Cover Latest Bluetooth Innovations” at 1:45 p.m. on April 10. A live demonstration of the measurements will take place at the Rohde & Schwarz booth 4-218 in hall 4 at the embedded world Exhibition in Nuremberg, Germany, April 9 to 11, 2024.
