Wireless Rulings

A Complex Solution

In a nutshell, wireless microphone users were granted a protected part of the spectrum, so in that sense, it was a victory. On a market-by-market basis, wireless mic users are protected in the two first-available channels above and below or closest to TV 37 (the protected radio astronomy band), but it might be 36 to 38 in one market and 35 to 36 in another. So it is incumbent on the operator to dial in what is what. If a local user or a touring act has a special event requiring more channels or greater protection, they are able to apply to the FCC for a protection extension with a 30-day advance that includes a period of public comment.

The problem right now is that it is not clear what guidelines will govern the application approval; nor has it been determined who, or what, will maintain a national database of licensed users that will be the primary source of protection for larger, fixed operators. The FCC left that decision for later. Google and other consumer-oriented groups have applied to be the administrator of the database, but more than one commentator has equated that to the fox guarding the henhouse.

Also, the FCC did not follow through on one of the key proposals from 2008 that would require unlicensed operators to employ sensing technology in every unit. That means your 4G PDA, tablet, or phone doesn’t have to check for unused frequencies and switch over when in conflict; it would have been too expensive per device, the consumer group argued. The FCC did, however, keep a provision from 2008 that requires geo-location technology in all unlicensed devices, meaning that they have to check in with the database of known broadcasters and wireless mic channels that have registered for protection, either temporary or permanent.

Nobody SVC has talked to during the past few months has expressed much worry about the Super Bowl or the Grammys, the 17,000-member congregation or Universal Studios theme park, the Bon Jovi tour or Bonnaroo. They will register; they will be protected. But problems may crop up with the mid-level act coming into Las Vegas without a tech-savvy production manager, or the 500-person congregation that has an Easter production with guest actors and a full-blown, all-in-ears backing band. Is it the musical director’s job to register? Or is it the head of the regional sound company who rented the extra transmitters, beltpacks, and antennae? These are the questions that can be headed off by those who look ahead, but as we all know in live sound, even the best laid plans can go awry.

The Status Quo-For Now

But the sky is not falling, as Winkler points out, a sentiment echoed by Mark Brunner at Shure. “The FCC ultimately listened to the needs of the professional wireless community and set aside two UHF channels to protect the majority of users,” Brunner says. “That is a victory. The FCC recognized our needs. But there is more to come, and every wireless user, big and small, needs to pay attention over the coming year. We still don’t know who will be maintaining the national geo-location database, so getting registered—especially for the mid-level church, event production, or regional theater—is critical. We are encouraging all of our users that if in doubt, apply for a license!

“This is not equivalent to two years ago, when we were told that we had to vacate the 700MHz band,” Winkler says. “That involved new products, updates, and changeovers. This is part of an evolution, of the eroding of the wireless spectrum. Most people should be OK, but everybody needs to pay attention.”
