Abstract
A mobile device can send and receive signals in a dedicated frequency band and receive signals in a separate frequency band separate from the dedicated frequency band. The mobile device can send one or more frequency band compatibility combinations each including first and second frequency bands, the first frequency band being in the separate frequency band and the second frequency band being in the dedicated frequency. The mobile device can listen, based on a received neighbor list, for a first signal that has a frequency in the first frequency band and for a second signal that has a frequency in the second frequency band. The mobile device can determine, based on the first signal, ranging information indicative of a range from the mobile device to a source of the first signal, e.g., to obtain improved accuracy ranging information.
