The 698 to 806 MHz band is the band typically used by low power auxiliary stations and wireless microphones. A report and order revising these rules is available on the FCC web site.
In a statement, also available on the FCC web site, Chairman Julius Genachowski said;
“Today the Commission is taking necessary and essential action to complete the digital television transition, by requiring wireless microphone users to exit the 700 MHz Band by June 12, 2010. Our decision will accelerate the buildout of 4G wireless networks, and will prevent interference with first responders who rely on the 700 MHz Band for mission-critical communications.”
While wireless microphones and other devices currently using the band must discontinue operation no later than June 12th, 2010, sale and import of new devices will be prohibited as soon as the rules are publish in the Federal Register.

FCC Enforcement Bureau issues statement on Enforcement Advisories

On January 15, 2010, Michele Ellison, Chief of the FCC Enforcement Bureau made a statement on the launch of a new initiative with respect to “Enforcement Advisories”.

This would seem to indicate that the FCC will be more aggressive with respect to enforcement moving forward, as evident by this quote from the statement;

“While most companies and individuals take their regulatory obligations seriously, some appear unaware of what the Commission’s rules require or choose not to comply. The Enforcement Bureau will continue to work proactively to bring these entities into compliance. By the actions we take today, we affirm our commitment to strong, vigorous, and fair enforcement of the Commission’s rules.”

VCCI 1 year grace period for 1 GHz+ testing

The VCCI Council posted a notice on its web site at detailing the planed implementation of the 1 GHz+ radiated emissions requirements. These requirements are based on CISPR22 Edition 5.

While the VCCI Council will begin enforcement of the new requirements on October 1, 2010, manufacturers will have the option of applying the old requirements until September 2011. The VCCI Council requests however that manufactures proceed with conformity to the new requirements on the original 2010 deadline date.

The VCCI Council gives justification for its decision based on the publication, August 21, 2009, in the Official Journal of the European Union, that extended the date of withdrawal of EN55022:1998 until September 30, 2011. EN55022:1998 is based on CISPR22 Edition 3, and does not contain requirements for testing above 1 GHz.

It is interesting to note that for product sold in the United States, testing above 1 GHz has been required for many years. In fact, Part 15.33 calls out that unintentional radiators can be required to be tested up to as high as 40 GHz.

What has been a major point of contention for some, is that no agreed method for site validation has been published for above 1 GHz for FCC testing. That being said, no significant reports of interference above 1 GHz from properly tested unintentional radiators have made the headlines either.
