Radio spectrum may be one of the most tightly regulated resources of all time. From cellphones to police scanners, from TV sets to garage-door openers, virtually every wireless device depends on access to the radio frequency wireless spectrum. But access to spectrum has been chronically limited ever since RF transmissions were first regulated in the early 20th century. Now that's all about to change. New technologies that use spectrum more efficiently and more cooperatively, unleashed by regulatory reforms, may soon overcome the spectrum shortage.
