In a particular aspect, an apparatus includes first communication circuitry configured to perform first fine timing measurement (FTM) operations with respect to a device to generate first measurement data. The first FTM operation correspond to a first frequency band. The apparatus includes second communication circuitry configured to perform second FTM operations with respect to the device to generate second measurement data. The second FTM operations correspond to a second frequency band that is different than the first frequency band. The apparatus also includes a processor configured to compare the first measurement data and the second measurement data.
