Kalispell, MT | Microphones... I am concerned about these devices as well, not about their affects on broadcast TV, although that is a very legitimate concern as well, but about their affects on wireless microphone users. The white spaces aren't "empty" as many have stated.
They are responsibly used and or enjoyed by millions of people in the United States. Concerts, Churches, Sporting Events, Video and TV crews, etc.
Some of us are using white spaces legally, most of us aren't because the FCC has until now provided no legal way to use them for concerts and churches (what I do). But we use them responsibly, and are careful to avoid not only TV channels directly but possible harmonics as they can also cause interference both ways.
We are being prepared to be put off the air by an onslaught of noise. No more wireless headset microphones at concerts, no more pastors walking around at churches, no more musicians having freedom to roam around, no more sporting events and outdoor events that can be freely wandered around by the presenters.
When Americans realize this, white space devices will be hated. But by the time most Americans realize how much wireless microphones really ARE important to them, it will be too late... | |

| Re: Microphones... The issue is um, the part where the legal use comes in... and there is plenty of it going on. Surprised it took this long for that point to be brought up about wireless audio equipment...
Shure has some interesting info on their site....
....This is a little bit of 'what they learned' from: »www.shure.com/ProAudio/PressRoom···ndex.htm ............
Before transmitting, the device must determine its precise location and consult a database of TV channels that are safe to use. If the device is within one kilometer of a location where wireless microphones are known to be in use, the device must move to a different channel or cease transmitting. Devices must check the database at least once per day, whenever they are powered on, and whenever their location changes.
• Wireless microphone users may register the location, time, and TV channels used for a program or event in the database. One-time, recurring, and permanent wireless microphone use will be accommodated. The FCC will solicit proposals from entities interested in creating and administering the database. According to the FCC ruling, “Sites with significant wireless microphone use at well defined times and locations may be registered in the database.”
• As a secondary protection measure, all devices must also utilize spectrum sensing to detect and avoid TV stations, wireless microphones, and other users of the spectrum, whether or not they are registered in the database. Spectrum sensing technology is still under development, but as it continues to mature it will provide an important secondary layer of protection against interference.
• Only fixed white space devices may operate in channels 2-20, and they may not use adjacent channels. These “open” channels will effectively be protected from white space devices and should therefore be especially desirable for general wireless microphone operation. ---
And this is where they learned it from...

What seems like more of a headache is the part about registering your location, such as a venue, or temporary events. That will cause some certain frustration and contention by both sides to be sure. | |

Kalispell, MT | One, there are a few legal wireless mic users (not many). Two, and more important, *everybody* in entertainment and almost every church uses these systems, which while technically pirate radio and illegal, have been blind eyed by the FCC for years. It's not just those of us who setup the wireless gear who are affected. It's all of you (and I can almost guarantee you're included in this group) who enjoy shows made possible by the use of wireless microphones.
The FCC has shown for years that they do not care as long as we're responsible and avoid causing any interference - which we are very careful to do. If they did care they'd figure out a way to license us and make money... | |

Mullica Hill, NJ | wait people have to be licensed to use wireless mics? i figured one just went down to a music supply store ment for something like a band and got the hardware. or nowdays just order it online.

See this is the same thing I am talking about. People just think the wireless spectrum can be used without consequence and it won't bother anyone. | |

Kalispell, MT | Technically yes, and 99% of us are not eligible to get those licenses either. Only TV stations can actually even get a license to legally use wireless mics (since they're also the legitimate license holders on the adjacent channels).
In reality, no one has cared for many years. Modern entertainment relies on the unlicensed use of wireless microphone systems, and no lawmaker in their right mind or FCC person would ban them or take enforcement action - it would affect almost every American directly or indirectly.
However, smothering them out of existence by crowding the spectrum - that's another story. And no, it's not that the richest biggest production companies won't find alternate frequencies - they will.
It's the rest of us, whose investment in wireless gear is a much bigger hit if it just turns useless overnight to allow "white space broadband"
And yes, those 60MHz range frequency-agile systems ought to be great to have... look at the price tag on them before you propose them! | |

I guess it is time to dust off the old soapbox then huh?
I HIGHLY doubt that suddenly one day White Space devices are going to render every frequency range for every wireless mic completely useless.
btw: »www.shure.com/ProAudio/Products/···_content
hmm... 2400 selectable UHF frequencies, across a 60Mhz band
Look at the specs, there is PLENTY of space not in the 700Mhz range to work in assuming they are completely polluted. | |

Keller, TX | Re: Microphones... My Sennheisers come in a wide variety of selectable frequencies, but the mics you buy are within a fixed spectrum within those frequencies. In other words, I had to research to see what the frequencies of the local TV stations were and then choose a slice of the spectrum that would be least susceptible to interference. So, while my mics are capable of operating outside of their fixed spectrum, it would take a mod from Sennheiser to make it happen. I don't know about Shures...
We've got about $4000 tied up in wireless mics. I guess I'll just move the receivers backstage so they're as close to the performers as possible. It's either that or spend more money to upgrade. Even if I upgrade, who's to say that the FCC won't auction off that chunk of the spectrum too? | |
