A network hub may be configured to dynamically select a desired frequency (among available licensed spectrum holdings of a carrier) at which to operate. A network hub may send a current geographic location of the network hub to a server computer, and, in response, the network hub may receive, from the server computer, multiple available frequencies at which a configurable software defined radio (SDR) of the network hub can be configured to operate. The network hub may perform a network scan to determine respective current conditions of individual frequencies of the multiple available frequencies, select a particular frequency based at least in part on the current conditions of the individual frequencies, and configure the configurable SDR to operate at the selected frequency.
