In a scathing report released Tuesday, congressional investigators outlined a pattern of mismanagement, dysfunction and abuse of power at the Federal Communications Commission under the agency's Republican chairman, Kevin Martin.

The report -- the result of a nearly yearlong, bipartisan investigation by the House Energy and Commerce Committee -- accuses Martin of manipulating data and suppressing information to influence telecommunications policy debates at the agency and on Capitol Hill.

The decision by the Federal Communications Commission on Tuesday to open up white space -- the unused frequencies between television channels -- to unlicensed Wi-Fi devices is being hailed by technology companies as the dawning of a new era in broadband Internet access.

But the ruling is also being harshly criticized by various trade groups, including the National Association of Broadcasters (NAB), which argues that both the FCC's procedure and the concept are flawed.

Embarq Corp. has revealed more details about its exploration of a program that tracked Internet subscribers' Web-surfing habits for advertising purposes, telling Congress that it performed the test on 26,000 customers in a Kansas town.

Building on an earlier response to Rep. John Dingell, chairman of the House Energy and Commerce Committee, Embarq CEO Thomas Gerke wrote in a letter late Wednesday that his Overland Park, Kan.-based company chose Gardner, Kan., for its test because it was Embarq's smallest market and near qualified technicians.

Congress has asked Embarq Corp. about its work with a company that tracks online subscribers' Web traffic for advertising purposes, part of growing concern about Internet privacy.

Overland Park, Kan.-based Embarq is the nation's fourth-largest traditional telephone company with 1.34 million high-speed Internet subscribers in 14 states. It has been linked in the past with NebuAd Inc., a company that works with Internet service providers to tailor targeted ads based on what Web sites a particular subscriber visits.
