Abstract
A system and method for improving the accuracy of a secure phase-based ranging procedure and a Direction Finding procedure. The method includes receiving radio frequency signals from a second communication device. The method includes operating in a first mode including generating first location data based on the radio frequency signals and, transferring the first location data to a second processor in compliance with a Bluetooth Host Control Interface. The method includes comparing one or more conditions to one or more threshold values and responsive to the comparing transitioning from operating in the first mode to operating in a second mode. The method includes, while operating the second mode, generating second location data based on the radio frequency signals and, transferring the second location data to the second processor at a higher data transfer rate than the transferring of the first location data to the second processor.
