We are from the Goverment and we are here to take your NEW wireless mic

Wi-Fi’s range is also set to increase significantly. In December 2011, the Federal Communications Commission announced a plan to transition unused over-the-air wireless bands into Super Wi-Fi. Unlike today’s Wi-Fi, which uses the 2.5-gigahertz and 5-gigahertz bands, Super Wi-Fi’s low frequencies (from 470 to 698 megahertz)

2.4 GHz, 5GHz and 6GHz are used now. Enterprise systems have been using 6GHz for a while. You are right. It is congested down in 2.4GHz. But, Line6 has new technology that makes it darn near impossible to lose signal and have it stomped by a router, other device, etc. In fact, there are theater companies using 20+ systems in NY with no issues, and no management software, certification, etc like Shure is pushing on us.

Wireless mics near TV Channel 21 and below (518MHz and below) will be fine for about the next 10 years. The FCC is still not done with their inventory. Congress recently passed a bill allowing for more consolidation. TV Channel 37 (608-614MHz) has been set aside for radio astronomy. There are bands close to 37, like Gx used by Sennheiser and others, that will be auctioned off for sure. But, it will take about 5 years for those to go away in most major markets.

There is now more ability to operate wireless than there has been, because of the consolidation, but that will change as the TVBDs come on-line. Word is, a church in the Seattle Area has been "warned" by Verizon to get off of their air space. Churches that think they can skirt the law are just unsafe places to attend in my opinion. If you want to give the proverbial finger and shoulder shrug to the government, after being warned for 5+ years, then that says something to me, and to God. But, the bible does say that there will be more than many not ready for something we have been warned about for over 2k years.

I certainly agree that churches must obey the laws regarding wireless microphones. I posted this because I see churches working toward a goal of more and more wireless microphones. The shrinking band width and uncertain future regulations might be another reason to ask why. If the user never moves more then 15 feet and never turns completely around then perhaps a mired mic would be a better choice.

I think it's to give the big rock show look and feel, if the big Christian rock band singer in concert has a wireless microphone, then the lead singer at the church needs a wireless mic. I've seen where people are glued to a microphone stand that might as well be bolted to the floor with a wireless mic, there is a simple solution, wrap the wire around the microphone stand, put a few cable anchor clips into the floor, then twist tie the cables to those. This is actually one of my summer projects, to tie up the mic cables in the sanctuary. The issue is that we sometimes move the cables, so I need something reusable.

Yeah it pains me when people come in and immediately ask for wireless. My first question is always "how many cartwheels are you doing"? Must be be some perception thing people have picked up.

I'll take wired mics, thank you very much. Yeah i have wireless for those impossible people, otherwise known as pastors.

I'm sure in few years we will have alternate reality wireless. It basically works by using wireless space in alternate realities. Just find a reality in which no technology has been invented yet and you will have plenty of wireless space.

Floor pockets (or subsnakes) and gaff tape.

To the spectrum problem, I have a hard time seeing how this new "Super Wi-fi" will work successfully. There's just no bandwidth. Even if all 200 MHz of UHF TV band were cleared out, no broadcasters, no Radioastronomy protection, no Land Mobile allocations, that's still only ten 20-MHz channels. Since in the major markets there are no vacant TV channels to begin with, there won't be anywhere to put this new Super Wi-Fi -- maybe a couple of slow-speed channels if some of the lower-power translator stations are bumped off, but no bandwidth in the big cities means no consumer buy-in. I think it's destined to fail. Not that they won't, in their infinite wisdom, try.

The problem is that as the frequency increases it gets harder and takes more energy to produce a good signal, this is why the 700MHz band is so valuable, being that it's reasonably low, the limited output of a cellphone .5w does well there. One of the problems is that TV contains a lot of information, so analog TV took a very wide band per channel (6MHz). In order to produce enough channels for the market it took from 54MHz to 88MHz (channels 2-6) and then added from 174MHz to 210MHz (channels 7-13), then from 470MHz to 900MHz for UHF. This has slowly been eroded away, first with the loss of channels 70-83 and then with the loss of 54-70. I think the next generation of TV will simply be internet based, effectively your television will become a Super WIFI device. This could actually free up a lot of frequencies, because not only TV, but a lot of mobile frequencies could also be freed up with a move to SuperWIFI. Of course SuperWIFI needs to compete with cell phone companies who have tons of money for frequency auctions.

We are from the government and we've now decided it doesn't matter whose transmissions step all over yours.

Have a nice day!

I think part of the issue is that there are a lot of churches are using old thinking, that any location that gets a microphone jack needs it's own channel. I was visiting a sister church in another town today, they have 48 jacks in their sanctuary, they have a 32 channel board, and use 3x32 patch panels, this gives the sound team the ability to plug in a wired microphone at nearly any point in their sanctuary, note the jack number, then plug that into a channel on their board. They use the easily removable tape, and then write the location on the board. The fellow running their sound system is replacing one of the patch panels with a different one. Yes I did offer to dispose of the surplus (and still functional) patch panel for him.

With all those jacks, they have 2 wireless microphones, one for the pastor and one for the worship leader. If you have the ability to plug a wired microphone in anywhere and keep the cables short, there is no reason for having a lot of wireless microphones.
