Re: [WISPA] tv white spaces update and a question for you guys
I do not know what you are asking. Marlon and I were debating what type of system we should try to get the FCC to allow us to use as a test bed system for experimentation with unused television channel space as a platform for broadband delivery. I think we are all talking about the same thing here but I am not sure what you are asking.

Re: [WISPA] tv white spaces update and a question for you guys
Marlon, I'm rather surprised that you would even mention 2.4GHz(wifi I assume) as a possible technology to use in these bands. Now that they have cellular technologies specifically designed for BWA purposes (Canopy and WIMAX are good examples) and given the possibility of a fresh start to using this spectrum, using an unarguably inferior technology for BWA like wifi just doesn't make sense. You end up with the craziness we have right now in the current bands. If testing data for equipment operation in that band is needed, you could probably obtain this information from a few companies off the top of my head like Qualcomm(Flash-OFDM), IPwireless(TD-CDMA) and Airspan(WIMAX and proprietary), that currently have experience w/ 700MHz. IMO if they ever release a 'WISP band'(which I would be surprised), they need to have a GPS synchronized transmission cycle as a requirement... Here's an idea, make WIMAX as the accepted technology for that spectrum. Then all you need is the WISP(s) in the area to coordinate transmission cycles to minimize interference potential. That leads to a whole other subject, if a 'wisp-band' were opened up, the WISP industry could potentially be a whole new ball-game...think companies(AOL, Speakeasy, Covad, etc) spending 10s of millions to go regional/nation-wide that you would otherwise potentially not have to compete against. Now THAT would be interesting :-) Jon Langeler Michwave Tech. Marlon K.

RE: [WISPA] tv white spaces update and a question for you guys
Ron, Where did this relevant paragraph come from? I like the mention of me but I can't take credit for it. I use the information from the FCC data, just happen to be pretty good at mapping the information. Most people could do a simple search channel by channel in the FCC database and get maps. This requirement should be easy to meet. I have said before that we should also be able to use the methods yet to be approved for 5.4 GHz stuff. If it's good enough not to broadcast over radar it should work for TV stations too. The idea of some FM or TV station sending some control signal scares me. That's like leaving the mouse in charge of the cheese factory. Who gets a say in what they put on that control channel. Spectrum sensing should be a no brainer and would work fine. It still irks the crap out of me that they worry about this anyway. So few people receive signals off the air that they won't notice any low power spread spectrum signals. Politicsat least all these failed muni projects will force some spectrum policy though. It'll take a couple of years but it'll happen.

"The Notice proposed to require that fixed unlicensed devices incorporate a geo-location method such as GPS or be professionally installed, and that they access a database to identify vacant channels at their location. It proposed to require that portable unlicensed devices operate only when they receive a control signal from a source such as an FM or TV station that identifies the vacant TV channels in that particular area. The Commission also sought comment on the use of spectrum sensing to identify vacant TV channels, but did not propose any specific technical requirements for devices that use spectrum sensing." The GPS requirement does not seem to present a problem, for Fixed Wireless, many GPs devices cna be incorporated into any PC. As for a data base that exists and is available from Brian Webster [EMAIL PROTECTED] , or could be accomodated to ID vacant channels at a given location. If this is all that is required the information is already available. For "Portable Unlicensed devices" the requirement is more difficult, I admit. But to runa test for fixed unlicensed devices this should be much more straight forward. What do you guys think? Ron Wallace Hahnron, Inc. 220 S. Jackson Dt.
