Warning that FCC plans to ban wireless microphone use in the 700 MHz band by February 17, 2009 “would needlessly harm users of such equipment,” the National Association of Broadcasters (NAB) and the Association for Maximum Service TV (AMST) echoed wireless mic manufacturer Shure, Inc. in urging the FCC to adopt a “reasonable” transition period that would give wireless mic licensees up to three years or more in which to terminate operations in the 700 MHz band. The companies presented their arguments in comments filed in response to an FCC rulemaking proposal, handed down in August, that would prohibit the production, shipment, import and sale of wireless mics and other low power auxiliary devices in the 700 MHz band upon completion of the digital television (DTV) transition next February. Although the goal of the FCC is interference protection for recently-auctioned wireless broadband licenses in the 700 MHz band, Shure warned that, owing to the number of 700 MHz wireless mics currently in use, an abrupt shut-off or even a short transition period would be “complex, costly, and disruptive.” Asserting that “it is not reasonable to expect these users to ‘turn on a dime’ and cease 700 MHz operations virtually overnight,” Shure told the FCC that wireless mic licensees should be given a minimum of 24 months to change their systems. Although Shure no longer makes 700 MHz wireless mics for sale in the U.S., the company also argued against a proposed rule that would prohibit U.S. manufacturers from producing 700 MHz mics for export, as it charged that such a rule “would be contrary to the public interest in strengthening the competitive position of U.S. companies striving to compete in foreign markets.” Meanwhile, as the NAB and AMST called for rules requiring the end of wireless mic use in specific 700 MHz frequencies and service areas by 2012 or 60 days prior to the start of operations by affected 700 MHz auction winners, the White Spaces Coalition (WSC) urged the FCC to penalize wireless mic manufacturers and users that knowingly sell or use the devices without required FCC licenses. Observing that there are “perhaps millions” of wireless mics that use the 700 MHz band while there are only 943 active low-power broadcast auxiliary licenses that are authorized to use the band, WSC proclaimed: “since Shure and other wireless [mic] manufactures are responsible for widespread unauthorized use . . . they should be subject not only to the Commission’s forfeiture power, but also be required to disgorge the profits realized by their unauthorized activities.”
