6 Summary

The upcoming Bluetooth Channel Sounding feature addresses the key requirements of Location Services solutions, including high accuracy measurement across longer ranges and increased security compared to the prior Bluetooth solutions. These key factors combined with Bluetooth LE technology’s low power attribute and the ubiquitous adoption in smart phones, consumer IoT, industrial and automotive applications, makes it an ultra-promising technology for high-accuracy, low cost, secure ranging solutions.

As a Bluetooth SIG associate member, Texas Instruments (TI) is actively working with the SIG on the specification of the Channel Sounding technology. TI CC2340R5 and upcoming TI Bluetooth LE devices support the upcoming Bluetooth Channel Sounding in the device’s RF core and as part of the Bluetooth stack in the Software Development Kit (SDK). All the Channel Sounding modes including Mode 3 phase-based ranging and RTT packet exchange are supported. To get more information regarding the upcoming TI channel sounding demos, tools and examples, please contact connectivity_auto_marketing@list.ti.com or your local TI sales office.

Note: The Bluetooth channel sounding specification is still in draft state. This application note will be updated as needed, depending on the updates to the draft specification before the final release.
