Wireless mic leaders react calmly to FCC broadband plan
" While the broadcast industry has indicated its collective dismay at some of the details contained within the FCC’s National Broadband Plan, two of the biggest players in the wireless microphone industry, Shure and Sennheiser, both urge audio professionals to remain calm. Christopher Lyons, Shure’s manager of technical and educational communications, and Joe Ciaudelli, Sennheiser’s director of market development and education, addressed the issue in separate recent communications.
While acknowledging that the proposed reallocation of 120MHz of spectrum space away from broadcast is a cause for concern, both wireless manufacturers pointed out that the plan is, at this point, more of an exploration of ideas and a call for studies on spectrum usage than a concrete proposal. As Ciaudelli said, “the report repeatedly calls for deeper, comprehensive studies on spectrum use. We encourage this, especially since the report focuses on the use of spectrum for distribution of content.”
“Certainly, reclaiming a big chunk of the TV band is worrisome for broadcasters, but this plan is really just a statement of goals and direction,” said Lyons of Shure. “And the timeline in the document — to have everything done by 2015 — seems awfully aggressive to us. Just look at how long it took to get DTV rolled out.”
The two wireless giants agree that the broadband plan’s language does not seem to represent a setback for the operators of wireless microphones. In essence, what the plan does is legitimize broadband penetration as a priority, which means that it will take on increased priority in the future spectrum ecosystem. However, the plan seems to go to great lengths to emphasize that existing users will not be disenfranchised.
A major part of the plan is the call for a full national spectrum inventory as a precursor to any reallocation. Considering that the national wireless database in the broadcast band (basically, below 698MHz) called for in the FCC’s Second Report and Order on the white spaces issue remains unresolved, it may be a bit far-fetched to believe that a full spectrum inventory can be accomplished in the two-year span suggested in the broadband plan.
Once that still-to-be-defined study occurs, the serious discussions will begin. Sennheiser’s Joe Ciaudelli said that the broadband plan focuses squarely on both TV broadcast and wireless microphones in a positive way. “Our view is that any credible study will reveal the high use of spectrum for content creation. The report specifically states, ‘changes to the TB broadcast spectrum on consumers, the public interest, and the various services that share this spectrum, including…wireless microphones.’”
Because the broadband report emphasizes the primacy of content creation and distribution, it seems clear that wireless microphones, like those used in broadcasting, will have some degree of protection once the plan is finalized. Another recent FCC document promotes a return to licensing of wireless mics for certain still-undetermined classes of users. It is assumed that license holders will enjoy protection from unlicensed users through the national white spaces database.
The bottom line is that any further spectrum changes will be a minimum of five years in the future and, given the historic pace of change in these areas, probably longer. In the meantime, the coast is (relatively) clear for wireless microphone and ear monitoring systems, making this the optimal time to upgrade in those areas.
As Chris Lyons of Shure said, “We’ve now gone through this with the DTV transition, and then with the 700 MHz rebanding. We’re now in a time window where professional wireless systems are legal and well defined, and all the manufacturers have product solutions in place. Our goal now is to remind people to replace their old 700MHz systems by June 12, and then continue our support and advocacy for the industry as the FCC explores the broadband issue.” "

FCC considers revised wireless microphone licensing scheme
" In the wake of its Second Report and Order on white spaces, the FCC is now considering expanding its licensing rules for wireless microphones, in-ear monitors, production intercom systems and similar equipment that operates in the TV broadcast (VHF and UHF) band. The FCC has invited comments from all wireless users on this topic.. ..the FCC extended the deadline for comments. The comment period has been extended through March 1.
..The FCC is seeking comments from wireless users that will assist them in determining who should be eligible for a wireless microphone license. "

FCC orders frequency changes for wireless microphones
" Sports production companies must change the radio frequency they use for their wireless microphones under an order issued last week by the FCC. The groups have until June 12 to find alternative radio frequencies — a task that could cost hundreds of thousands of dollars for each organization. The FCC’s ruling is part of a national shift on the reallocation of bandwidth, which some say will soon be in short supply due to the increasing use of mobile telephones and wireless computers. The commission said the wireless microphone transition is necessary to make spectrum in the 700MHz band available for use by next-generation wireless services for consumers and public safety agencies.

Broadcast associations advise FCC on national broadband plan
" As the FCC considers how best to allocate spectrum while developing a national broadband plan, it should assign a premium to public policy goals being served by current spectrum use, the NAB and Association for Maximum Service Television (MSTV) told the agency in comments filed last week.
The comments, filed Oct. 23 in response to a commission inquiry into spectrum for broadband, offer the advice in answering a specific question posed by the commission in seeking comments: What are the key issues in moving spectrum allocations toward their highest and best use in the public interest?
The added public policy consideration given existing spectrum while assessing its “efficiency and productivity” should take into account more than financial benefits, the associations said. For instance, as relates to broadcast TV, “core public interest goals,” like providing local news, emergency information, universal service and educational programs, must be taken into account. According to the filing, “to ignore the public policy goals underlying the TV broadcast service would lead to spectrum management decisions that disserve the public interest.” "

White Spaces: Austere And Somewhat Unclear Microphone Embraces
" A primary concern for the pro audio community.. has been that such devices would create interference with critical equipment, such as wireless microphones. After considerable lobbying from the pro audio community, NAB, end users, broadcasters and others, the FCC would appear to have taken those concerns to heart with the new rules. As part of the Order, two channels will be set aside nationwide for wireless mic use-a move that the FCC expects will allow between 12 to 16 mics in a given area to operate simultaneously without interference from devices that will use the newly released spectrum. If a production requires more spectrum for an event such as a sports game or concert, it can petition for a temporary expansion of allocated frequencies during performance times by electronically filing a request with the FCC at least 30 days in advance. A condition of the additional spectrum being granted will be that users will have to prove that the additional channels have been exhausted, but critically, a wireless mic user does not have to be a licensed operator to register with the database.

Please read my latest article about TV tuners and especially look at the figure in the sidebar. That figure explains how digital and software engineers with absolutely no conception whatsoever of how RF and radio in general work, have conned the US government into allowing a slew of unlicensed intentional interferes to occupy our TV spectrum.

FCC Broadband Plan: Reactions Pour In
" Comments from Washington came pouring over the electronic transom Monday as details of the FCC's national broadband plan were revealed. Broadcasters said they would look closely at the plan, though they were pleased with the voluntary nature of any spectrum-reclamation proposal, so long as it stayed voluntary, while the main cable trade group also took a wait-and see approach, saying the report contributed to a dialog that needed to continue.
The plan appeared to be going over well with some key congressmen.. .."The commission has done a superb job in meeting the challenge set forth by the Congress one year ago that a national plan to achieve universal broadband access be developed,"..
..The National Association of Broadcasters, which has balked at mandatory spectrum reclamation and suggested broadcasters will need their spectrum for HD and services like mobile DTV, said it would vet the plan and hoped Congress would do the same. "We were pleased by initial indications from FCC members that any spectrum reallocation would be voluntary, and were therefore prepared to move forward in a constructive fashion on that basis"..
..The wireless industry, which has been pushing the FCC to find as much spectrum as possible for all those broadband apps, sounded happy. "The Wireless Association and our member companies are extremely pleased that spectrum is recognized as being pivotal to the National Broadband Plan.. We appreciate the FCC's and the broadband team's focus on making 500 MHz of spectrum for broadband within 10 years, of which 300 MHz should be made available for mobile use within five years."
..The National Broadband plan could force television broadcasters to change channels and reduce service areas, perhaps stranding millions of viewers. And "non-volunteers" might be punished with onerous spectrum fees and other indirectly coercive measures. "

" The wireless industry agrees with broadcasters that the FCC should keep the public interest in mind when it decides "how the broadcast television spectrum should be allocated," but says that would "clearly favor reallocation of broadcast television spectrum for commercial mobile wireless broadband users." That came in reply comments to the FCC, which is collecting input on how to get more spectrum for wireless broadband. CTIA said the FCC should not just reallocate any spectrum, but "the right" spectrum. And it made clear that includes broadcasters' spectrum. "
