A method for acquiring spectrum beyond the licensed spectrum for wireless network communications comprising accessing a geolocation database to determine a configuration of white space frequencies that may be available and transmitting the carrier aggregation configuration to user equipment (UE). The carrier aggregation configuration may be at least partially encrypted with the key sequences for the encryption being optionally changed for improved security. The white spaces may be activated in a handshake sequence in which a network node transmits an enabling signal to UE, receives an enabling request from UE specifying which white spaces are requested, and transmits an enabling response. In an alternative to transmitting an enabling response, the node may activate the requested white spaces in an LTE signal.
