In a letter to FCC Chairman Kevin Martin, National Systems Contractors Association (NSCA) Executive Director Chuck Wilson expressed concern regarding white spaces proceedings and new television bandwidth devices.
"Our members are alarmed by preliminary public reports about the FCC's inconsistent sensing results," Wilson said. "These inconsistent field tests present a very serious reliability issue that will impact our members and their ability to do business."
Early reports indicate mixed results in the field. Some suggest that low-power wireless devices may interfere with the DTV spectrum. Supporters of these prototype white-space devices – which include laptops and smart radios – are vying to share the unused, or "white spaces," portion of the television spectrum. The FCC is conducting tests to ensure these devices don't interfere with digital reception.
As recently as August 9, the FCC conducted a test of white spaces devices before and during the Buffalo Bills-Washington Redskins game in Washington D.C. The result showed that the prototypes did not accurately sense wireless microphone signals, a function that would be required to prevent interference.
