Of course more spectrum is good, but are you saying that in 50 years, we won't have bested 2.5 bit/Hz in PtMP gear and 10 bit/hz in PtP gear (which alone points out a 4x difference)?
There's not that much more spectrum to be had... frankly I'll be surprised if in the next 10 years we get anything more than what's in the NOI or NPRM stage now (which I think includes BRS\EBS whitespaces). There just isn't that much left to be had... unless you go way up there, but then 70\80 already has that pretty well with what, 10 GHz of spectrum available? Since better gear has already demonstrated itself, I think we'll have to see more of that before we get more spectrum, if we get any more at all. I think our only other option would be a long range UWB or whatever those clowns in Florida were working on... I forget what or who now. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com -------------------------------------------------- From: "Jack Unger" <[EMAIL PROTECTED]> Sent: Tuesday, November 25, 2008 1:01 AM To: "WISPA General List" <wireless@wispa.org> Subject: Re: [WISPA] NetFlix Streaming Bandwidth Information > Drew, > > As I've mentioned before - wireless "physics" does not allow you to > simply and affordably "build your network" for tomorrow but you do not > yet understand this point.
