Abstract
Methods and systems are provided for dynamic allocation of carrier frequencies in wireless wide area networks (WWANs). A first base station among a plurality of base stations in a WWAN determines that a level of load in a wireless coverage area exceeds a load threshold, and responsively (i) obtains a first keycode from a keycode library, wherein the first keycode then becomes unavailable to the other base stations of the plurality of base stations, (ii) identifies a carrier frequency, and (iii) uses the first keycode to activate the identified carrier frequency in the wireless coverage area.
