Systems and methods for controlling a frequency band of operation of a base station
The present disclosure relates to controlling a frequency band of operation of one or more base stations in a cellular communication network based on associated parameters of air interfaces of the one or more base stations. In one embodiment, a control element of the cellular communication network obtains parameters for an air interface of a base station. In addition, in some embodiments, the control element obtains one or more parameters for air interfaces of one or more additional base stations. Using the one or more parameters, the control element obtains a decision to switch a frequency band of operation of the base station from a first frequency band to a second frequency band. In response, the control element sends a command to the base station to switch the frequency band of operation of the base station from the first frequency band to the second frequency band.
