The government might also require some broadcasters that do not participate in the auctions to move to new frequencies, a process known as "repacking."
The legislation would also allocate spectrum for a nationwide broadband network for first responders.
The National Association of Broadcasters argues the plan could force broadcasters in Detroit off the air because of a treaty with Canada that prevents them from accessing Canadian spectrum.
“NAB appreciates Rep. Conyers’ support for an enduring American institution: free and local television," said Dennis Wharton, NAB's vice president of communications. "We look forward to working with him and other policymakers to avoid a reckless repacking of TV spectrum that would hinder the ability of local stations to serve communities with quality news, entertainment and life-saving emergency weather warnings.”
Conyers said he plans to communicate his concerns to other lawmakers and the FCC.
"While I agree that first responders must have enough spectrum and funds to roll out a national communications network for public safety, we must also ensure that local broadcasters are not harmed in this process," he said. "In the coming days, I plan to reach out to the FCC and my colleagues in Congress to ensure that Detroit broadcasters are not harmed in any potential future auction authorized by the FCC or proposed in any new legislation."
