Abstract
A method is disclosed for implementing an overlay carrier frequency in a wireless coverage area in response to low load in the coverage area. Normally, an carrier frequency may be added in response to high load. However, the disclosed method involves adding a carrier frequency in response to low load, as the addition of a carrier may advantageously increase the likelihood of soft handoff in certain situations, and as low load may facilitate operation on the added carrier without the need to add expensive supporting infrastructure that would typically be added to support full operation on an added carrier frequency.
