Rohde & Schwarz First Demonstrates Innovative Bluetooth Channel Probe Measurements to Improve Positioning Accuracy

According to foreign media reports, Rohde & Schwarz (Rohde & Schwarz) will be the first to plan to develop a new Bluetooth®The signal is measured in real time to support the channel sounding (Channel Sounding) function., (Image source: Rohde & Schwarz), at the Nuremberg Embedded System Exhibition (embedded world Exhibition & Conference), the company will demonstrate on the R & S CMW500 broadband radio communication test machine. The Bluetooth channel detection function (Bluetooth®Channel Sounding) will provide unprecedented positioning accuracy for consumer and commercial applications. This signal measurement capability to support chip and device development is eagerly anticipated by the industry., For consumer and commercial devices, Bluetooth®It is the most widely installed technology with positioning function. The upcoming channel detection feature will significantly improve the use of Bluetooth®to determine the accuracy of the location of the real-time positioning service (capable of reaching 50cm or higher)., In addition to improving positioning accuracy, it is expected that the channel detection function will be better than the existing Bluetooth®Location services consume less power and provide greater security. Improved accuracy will be an important step forward, especially for indoor applications such as asset tracking on the factory floor or warehouse, and secure access to buildings or vehicles., In order to support the improved positioning function, Bluetooth on the new physical layer is required®Device hardware changes. Engineers who want to start developing the necessary chips and devices (including channel sounding support devices) are in dire need of reliable and accurate signal measurements to implement new functions. Rohde & Schwarz has prepared options for its R & S CMW platform to support corresponding RF physical layer measurements., Next version Bluetooth®Support for phase-based ranging (PBR) tone swapping and round-trip time (RTT) is identified in the preliminary design of the Core Specification., return to the first electric network home>,
