Groups including the Grand Ole Opry and MTV are petitioning the Federal Communications Commission to oppose plans by Google and Microsoft to use the so-called "white spaces" between broadcast channels for wireless devices.
The groups say allowing millions of wireless devices to use the same frequencies as wireless microphones would be a "catastrophe," reports Reuters.
So far, devices built by Microsoft and tested before the FCC to effectively find the "white spaces" have failed. The requests by Google and others to use the spaces has been considered a ploy to get spectrum for free.
The National Association of Broadcasters maintains using the spaces will interfere with broadcast signals, the reason signals were spaced out in the beginning. Sports groups including the NFL, NASCAR and NBA also argue that using the spaces will interfere with wireless microphones, according to The Washington Post.
And health officials are worried that use of the spaces will interfere with hospital telemetry systems used to monitor patients.
