The amount of wireless spectrum available in the United States would nearly double over the next 10 years as the federal government prepares to gradually auction 500 megahertz of federal and commercial spectrum.
In past decades, new spectrum auctions have been the foundation for potential assaults on industry structure, allowing new contestants to enter the market. Whether that will be the case in the forthcoming auctions remains to be seen.
Clearwire and Sprint have plenty of spectrum, while AT&T and Verizon Wireless are launching new Long Term Evolution networks that are far more spectrally efficient than the third generation networks they will supplement and then replace.
T-Mobile USA needs more 4G spectrum, but probably cannot afford to buy new licenses. The issue is whether any truly-new contestants are willing to take a chance on disrupting the business.
