A radio access network (RAN) may receive indications from a wireless communication device (WCD). The RAN may support wireless communication via a plurality of non-overlapping frequency bands, and the plurality of non-overlapping frequency bands may include a low-frequency band and a high-frequency band. The low-frequency band and the high-frequency band may be separated by at least 5 megahertz. The indications may indicate signal strengths at which the WCD received signals from one or more frequencies in the low-frequency band and one or more frequencies the high-frequency band. The RAN may also receive a communication request from the WCD. Based at least in part on receiving the communication request, the RAN may select a frequency from the one or more frequencies in the low-frequency band and the one or more frequencies in the high-frequency band, and may instruct the WCD to communicate using the selected frequency.
