CEVA Introduces Channel Sounding over Bluetooth to Enable High-Accuracy Secure Positioning

CEVA has announced support for Channel Sounding to its RivieraWaves Bluetooth IP portfolio, meeting the surging demand for high-accuracy secure positioning in the automotive, industrial and broader connected devices markets. This low power positioning technology is ideal for secure distance bounding applications such as secure vehicle entry, access control, asset tracking, and more.

CEVA announced the general release of its RivieraWaves Bluetooth 5.1 IP and multiple license agreements already signed with leading semiconductor companies. Supporting the headline new feature of Direction Finding via Angle of Arrival (AoA) and Angle of Departure (AoD) for enhanced location services, the RW-Bluetooth 5.1 IP is available in both Bluetooth Dual Mode and Bluetooth Low Energy flavors.

The Bluetooth Special Interest Group (SIG) announced a new direction finding feature that holds the potential to significantly enhance the performance of Bluetooth location services solutions, down to centimeter-level location accuracy. The new feature, included in version 5.1 of the Bluetooth Core Specification, allows devices to determine the direction of a Bluetooth signal, thereby enabling the development of Bluetooth proximity solutions that can understand device direction as well as Bluetooth positioning systems.
