radio-wave.jpg The potential for cognitive radio technology to redefine existing wireless services becomes clear when one considers their economics. A monthly cell-phone service bill, for instance, contains charges for leasing radio spectrum, renting cell towers and purchasing the handset, as well as the amortization of the hardware at the cell base site, the cost of interconnections among cell sites, billing expenses and network operator profit. These fees pay for the investments that cellular service providers make to create and operate dedicated RF networks.
