Field Testing Sets Off “White Spaces” Alarms

In a letter to FCC Chairman Kevin Martin, NSCA Executive Director Chuck Wilson expressed concern regarding white spaces proceedings and new television bandwidth devices.

As recently as August 9, the FCC conducted a test of white spaces devices before and during a Buffalo Bills-Washington Redskins game in Washington D.C. The results showed that the prototypes did not accurately sense wireless microphone signals, a function that would be required to prevent interference.

“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.

Because NSCA members design, install and maintain sophisticated integrated A/V, security and communication systems for a wide variety of venues, wireless components play a critical role in system design and functionality.

Wilson urged the FCC to conduct further field testing to ensure consistent and reliable results using a diverse array of usage environments.
