Abstract:
1. A method comprising: a radio access network (RAN), receiving one or more indications from a wireless communication device (WCD), wherein the RAN supports wireless communication via a plurality of non-overlapping frequency bands, wherein the plurality of non-overlapping frequency bands includes a low-frequency band and a high-frequency band, and wherein the one or more indications indicate signal strengths at which the WCD received signals from one or more frequencies in the low-frequency band and one or more frequencies in the high-frequency band; the RAN receiving a communication request from the WCD; based at least on (i) receiving the communication request, (ii) the indicated signal strengths, and (iii) previously-obtained indications of the WCD's location, the RAN determining that the WCD has moved a distance of at least n meters over the previous t seconds, wherein n and t are both non-zero; based on the WCD moving the distance of at least n meters over the previous t seconds, the RAN selecting a frequency from the low-frequency band; and the RAN instructing the WCD to communicate using the selected frequency.
