Silicon Labs and Nordic Semiconductor simultaneously announced hardware support for the specification. Channel sounding is a part of the newly adopted Bluetooth 6.0 specification.<\/span><\/p>\n<p><img decoding=\"async\" style=\"width: 100%;\" src=\"http:\/\/file.flywing-tech.com\/res\/article\/20240928180605657ed203172e79792ada72caa9bf8b2dab31c89.png\" alt=\"\" data-href=\"\" \/><\/p>\n<p style=\"text-align: center;\"><em>Bluetooth channel sounding has applications across homes, businesses, and factories. Image used courtesy of Silicon Labs<\/em><\/p>\n<h5 style=\"text-align: center;\"><\/h5>\n<p style=\"text-align: start;\">Bluetooth low energy (BLE) supports a certain range and device detection starting with specification version 5.4. The previous BLE ranging solution, however, has limited range accuracy. The new 6.0 version comes with significantly greater precision, enhanced flexibility, and stronger security.<\/p>\n<p style=\"text-align: start;\">All About Circuits last <span style=\"color: #ff7a45;\">covered this subject in February<\/span> before the final acceptance of the 6.0 specification. Since then, the Bluetooth SIG and industry partners have finalized and accepted the specification and started developing supporting hardware.<\/p>\n<p style=\"text-align: start;\"><strong>How Bluetooth Channel Sounding Works<\/strong><\/p>\n<p style=\"text-align: start;\">Channel sounding is a new protocol stack for Bluetooth 6.0 hardware. The protocol relies on two methods to deliver higher accuracy and greater reliability than was previously possible. The primary ranging system uses phase-based ranging (PBR). The secondary ranging method called round trip time (RTT) is an optional add-in to improve accuracy and reliability.<\/p>\n<p style=\"text-align: start;\">PBR captures the change in phase in a reflected carrier wave. BLE operates at 2.4 GHz, which (calculates at 1\/f) to 12.5 cm (4.92\u201d) wavelength distance. The device initiating the inquiry (the initiator) transmits information about the signal phase and amplitude through amplitude shift keying (ASK). The receiving device, referred to as the reflector, sends the signal back to the initiator, which determines the phase change and amplitude. It then translates the difference into distance based on the phase difference related to the 12.5-cm wavelength.<\/p>\n<p style=\"text-align: start;\"><img decoding=\"async\" style=\"width: 100%;\" src=\"http:\/\/file.flywing-tech.com\/res\/article\/202409281806316310fa603bd645093a2376dcd4b0e6966d4cb5a9.png\" alt=\"\" data-href=\"\" \/><\/p>\n<p style=\"text-align: center;\"><em>Phase-based ranging comparing the change in phase between transmitted and received signals. Image used courtesy of Silicon Labs<\/em><\/p>\n<h5 style=\"text-align: center;\"><\/h5>\n<p style=\"text-align: start;\">RTT is the less complex of the two methods. It simply needs to measure the time between transmit and receive. Time of flight (TOF) is half that time, with fewer processing-related delays in the reflection system (Treflector). Flight time is difficult to manipulate, adding to its security. The primary disadvantage of RTT is the very small time values involved. If the clock speed is not high enough, the accuracy of the TOF result will be imprecise.<\/p>\n<p style=\"text-align: start;\"><img decoding=\"async\" style=\"width: 100%;\" src=\"http:\/\/file.flywing-tech.com\/res\/article\/2024092818065065085a657b7ab5ec5bba59ceee65f0a8fd887cdd.png\" alt=\"\" data-href=\"\" \/><\/p>\n<p style=\"text-align: center;\"><em>RTT distance calculation. Image used courtesy of Silicon Labs<\/em><\/p>\n<h5 style=\"text-align: center;\"><\/h5>\n<p style=\"text-align: start;\">Both BLE 6.0 methods are highly secure. In addition to its multi-layer security measures, the BLE protocol has physical properties from two distinct methods rather than just digital data, making the ranging system inherently more difficult to manipulate for nefarious purposes.<\/p>\n<p style=\"text-align: start;\"><strong>Silicon Labs Jumps on the Channel-Sounding Bus<\/strong><\/p>\n<p style=\"text-align: start;\">Silicon Labs will be adding Bluetooth 6.0 channel sounding to its xG24 platform.
