A multipath condition detection method includes: determining a first signal quality value corresponding to a first wireless signal, of a first frequency and from a signal source, received by a receiver of a mobile device; determining a second signal quality value corresponding to a second wireless signal, of a second frequency that is different from the first frequency, received by the receiver; and determining whether at least one difference value, corresponding to the first signal quality value and the second signal quality value, is indicative of the mobile device being in a multipath condition with respect to the signal source.
