According to the U.S. Federal Communications Commission chairman, the rapid growth in bandwidth usage by mobile devices like the iPhone threatens to overload the available electromagnetic communications frequencies - or "spectrum," as the FCC refers to it - allocated to such devices. As a result, creative new policies will have to be implemented to avoid a "spectrum gap," the chairman said.
In a Q&A with Business Week, FCC chair Julius Genachowski said that if current trends continue, there will not be enough spectrum available for the growth in mobile broadband access.
