CEVA Introduces Channel Sounding over Bluetooth® to Enable High-Accuracy Secure Positioning for Automotive, Industrial and the IoT Ecosystem
New low power positioning technology ideal for secure distance bounding applications such as secure vehicle entry, access control, asset tracking, and more
Channel Sounding (previously referred to as HADM – High Accuracy Distance Measurement) is a radical improvement on traditional Bluetooth distance and position measurement techniques, namely received signal strength indicators (RSSI) with angle of signal arrival/departure (AoA/AoD). The additional security and accuracy over previous generations of Bluetooth positioning, coupled with its low power profile, makes Bluetooth-based Channel Sounding ideal for applications such as automotive digital keys, and for general applications such as industrial / warehouse / consumer asset tracking, and real-time sport/fitness tracking.
CEVA's implementation provides best-in-class decimeter-level accuracy in complex, multi-path real-world environments. This robust, low power architecture, developed from over twenty years of field experience in Bluetooth connectivity, incorporates advanced security mechanisms to defeat distance-spoofing and 'relay attacks', an essential requirement for next generation digital keys and wireless payment systems.
Tal Shalev, Vice President and General Manager of the Wireless IoT BU at CEVA, stated: "Channel Sounding for Bluetooth addresses an urgent need expressed by many of our automotive and industrial customers for a robust, low power, low-cost positioning solution. Along with UWB-based positioning that it can be combined with for even more demanding positioning applications, we offer a comprehensive and unrivalled portfolio of wireless technologies to meet the diverse needs of our customers."
Beyond the demanding secure vehicle entry segment, Bluetooth-based positioning is well established as an asset tracking solution in industrial, warehouse and consumer applications. It is also experiencing a new wave of growth in the retail location services segment, especially when coupled with the increasingly popular Bluetooth-based Electronic Shelf Label (ESL) systems. The extra level of accuracy and security now possible through Channel Sounding in Bluetooth-based positioning will further accelerate the massive deployment of such systems.
CEVA's technical experts will be available to discuss Channel Sounding for Bluetooth at MWC Shanghai 2023 (June 28-30). Visit CEVA's booth N2.EMR04 in Hall 2 at the show to meet the CEVA team and interact with the latest wireless connectivity and smart sensing technology demos on display.
CEVA's Channel Sounding for Bluetooth will be available for general licensing in September 2023.
