It's not a question of whether this will increase the noise level. It will. By it's nature it is impossible to not increase the noise level. And that definitely will degrade all signals sharing the band. (Which is pretty much everybody.) The only question is whether the degradation will be enough that you will notice.
It's like someone whispering during a college lecture. The sound goes everywhere in the room. Most people can ignore it. Some may have more difficulty. If the whispering is quieter fewer will be bothered. But all experience some degradation. And if half the people in the hall are whispering it becomes very noticeable. -- Allen Brown abrown at peak.org http://brown.armoredpenguin.com/~abrown/ Don't let schooling interfere with your education. --- Mark Twain ----- Original Message ----- From: "Michael Miller" <mike.mikemil...@gmail.com> To: "Eugene Unix and Gnu/Linux User Group" <euglug@euglug.org> Sent: Friday, July 29, 2011 10:28:00 AM Subject: Re: [Eug-lug] White Space Well it's already a issue due to unlicensed wireless MIC's using this spectrum. I've not the 802.22 standard yet. I don't think they set any power limits in that spec. That's the FCC's job and I've not seen any power output specs yet. I'm willing to guess it's going to have the same power restrictions as the ISM band. Added with the additional GPS receiver so it can pull what channels are in use and go to a unused channel. I don't know if very many consumers will want to get 802.22 equipment. Just because of the higher regulations that you are going to have to ad-hear to. My reply to your "radio signal degradation comment." is I don't think this is going to happen. Like I said before it's going to be highly regulated. More so than normal ISM equipment, and it's a waste of spectrum. It's better that the public will be able to use it vs the government selling it off to a telco. The up shot is you don't have to spend a lot of money on a higher gain antenna. You can use a off the shelf TV antenna. --mmiller On Thu, Jul 28, 2011 at 10:15 PM, <abr...@peak.org> wrote: > I'm not looking forward to this.
