2 edits | It has to do with trunking pairs. Modern public service communication uses a trunked system where you have number frequency pairs. Using a computer that keeps track of what pairs are in use when a fireman, policeman keys up his radio it sends out a tone sequence which ID's the radio. The trunking system then assigns an open frequency pair to this radio. This all happens on the fly so each time the radio is keyed it gets a vacant frequency pair. The reason for a frequency pair is these system use repeaters. Repeaters are located it areas that can over look a given area, or on towers doing the same thing. this vastly increases the range of a public service radio. Repeaters transmit on one frequency and receive on another. With a trunked system these frequency pairs are agile as well. The problem is there are only do many frequency pairs so if there is heavy use of such a system it can delay a fireman, or Policeman communicating with his dispatcher, or fellow cop's and if it a life or death situation, you get the point. This is one of the reason why many public service organizations are adding cell phones to this mix. More frequency pairs would mean faster communications. I have not even got into the growing number of radio linked computers used by law enforcement requiring band width.
Of course Motorola, Vertex, GE, Collins-Rockwell all would be ready and willing to fix this problem selling ($$$$$) radios making use of 700 MHz.
More and more of this is going to happen. Amateur radio has a number of frequency bands in the VHF, UHF, area that would be a real money maker if one of the makers of public service radio if they could get their hands on them. We however are a licensed service so it would not be as easy as it was screwing over the people using 700 meg wireless mic's

| Re: 900Mhz? said by FBGuy:good grief! no wonder they think they need so much bandwidth. maybe they should learn to use what they have and stop overextending themselves. I do think that law enforcement is necessary and everything but they need to learn to do the job they are paid to do without all this technology. Actually the point of trunked radio is to CONSERVE bandwidth. I run a 14 channel trunked radio system with over 150 disctinct talkgroups. Would be impossible on a conventional radio system.
Please try to at least learn a *little* about things before you pass judgement in the future. That job they are paid to do would be impossible to do without "all this technology." We are already stretched threadbare thin budget and manpower wise. The tech makes us more efficient. This SAVES money and resources which is just one of the many benefits of "all this technology." | |

Exactly, A county/city can run a 250 Channel/talk-group system with maybe only 12-16 Frequency's (6 -8 conversations/trannmissions at once) Maybe less.

I could see 902MHz and 1.2GHz going commercial since they are pretty much underused.
2 meters, not really. Lots of international signals from satellites and others. 2M is mostly safe.
222MHz - we lost part of that band to UPS but it was pretty much wasted by them. I don't know if we'll lose the last 3MHz of it.
70cm - safe because we are secondary to the US Government (PAVE PAWS).
6 meters - not desirable due to noise and reflections (propagation!) | |

There's lots of pro gear in that band where a 5-10 year lifetime is expected. If I'd plunked down a few grand for a nice mic and receiver 5 years ago, you'd have to pry that stuff from my cold, dead hands.

Faison, NC | not a big deal Considering the very limited range that microphone transmitters have, often they don't have enough to cover an entire room adequately, I don't think they would cause problems for wireless . I doubt many places that use them even know what frequency their system uses so I don't expect there to be a mad rush on wireless microphones.
This is more about no new 700mhz systems being sold. I expect ebay will have quite a few 'specially priced' systems. | |

I think the bigger issue is that more and more repeaters are going to be used that might pick up those weak signals, and completely screw things up.
Personally I think the FCC needs to do an equipment buy back, using the money they are charging for the spectrum to replace the equipment people are using.

Hickory, NC | Re: not a big deal I agree with you about the buyback program.

Now I'm supposed to stop using them without any offer to buy them back or give me a HUGE break on replacing them? The FCC can kiss my @$$. | |

All the while the FCC will collect more for the spectrum you are no longer allowed to use.
For induviduals it sucks. But I've also worked with a lot of community theaters, donation funded, that are going to have to replace every mic they own. In this economy.

| | How are they going to catch violators? So FCC order those that use wireless microphone off the frequency, that is nice but it comes with a big BUT. Say i am home owner and my kid has wireless microphone. I unlikely to know the frequency of it, and second i am unlikely to care assuming i am even aware of the FCC order. Being that the range is pretty small, it's unlikely for signal to go past my house. Even if the signal does get out, how are they going to catch me?
FCC order is without any teeth and likely to be ignore by many | |

kudos:1 | I agree. I am not concerned about willful violators. I am concerned about the hundreds of thousands of people who have no idea this is happening.
A news article on DSLR, a blurb on the FCC's website, and some posts that become buried on blogs and tech news sites is not enough. In spite of the amount of sources we have for news in this country there are still a lot of people out there who had no idea we captured Saddam for months after it was in the news.
This band is going to be used for emergency services. They need to knock in every door along with the census people to ensure everyone is aware of this: not for our sake, but for the sake of the people who depend on those emergency services!

1 edit | The FCC is dreaming.. Yeah.. It's not the broadway theaters, broadcasters, A/V shops, touring productions, etc that they have to worry about..
It's the weekend musicians, aerobics instructors, health clubs, churches, shopping malls, etc who bought systems, or had systems installed, and have no idea what frequencies their systems operate on..
Look at the DTV transition fiasco... Folks got how much warning? and were still unprepared, despite large amounts of public outreach on the media.
The problem is that many of the folks affected don't read the trade magazines, and probably have no idea how to determine what frequencies their equipment operates on, or have any budget to replace it, especially if they purchased it in the last couple of years, and are expecting to get a 10 year lifecycle out of it.
6 months to clear the band of tens or hundreds of thousands of wireless mics that may see use anywhere from several hours a day, to once or twice a year.. They really need to allocate 5-10 years.. | |
|
| | How much... did Verizon, AT&T, and the others pay the FCC under the table for the frequencies? Was it in cash or in drugs or in hookers or all three? | |
