Hello Bernard, it's me... the gadfly in your blind spot, up in the front of the room just to your right, as you make eye contact with those in the middle and rear of the room. -s- Of course, some of my message was to provoke, while on some other level I was dead serious. Yes, there are disparate criteria and varying tradeoffs between higher and lower frequency bands, and those interfacing schemes which are simpler and those which are more complex. I don't have any explicit solutions to offer, of course, only musing on some level, thinking aloud, more or less. Perhaps drilling down to a narrower set of LCDs reduces the complexities of what I've suggested. And where that is not possible, then the more unique (vendor-specific and proprietary) modes should prevail. Where distances AND line of sight issues render the conditions extreme, set out to implement more towers, or where line of site is an issue, bring it to the general target vicinity (the neigborhood) via lower frequency bands over greater distances, and then upshift to the higher bands closer to the targets via translators to the home, etc., using enclosures similar to optical network units in the HFC/PON mdoel, only in this case using wireless. Only the bravest vendors and those with the deepest pockets need apply to this idea during the initial crossings, while the others continue in their proprietary ways. Kevlar arrow vests, turned around to the rear, would also help. Begin Sidebar: While I see the trend already emerging, I actually submit these ideas here as a form of academic exercise, in the same spirit as I once exchanged another set of concepts with George Hawley some time ago here in LMT. I had suggested a broadband DSL, VDSL specifically, scenario for business customers. I went to some length to demonstrate how fiber rings in the World Trade Center (using the Twin Towers in NY City as an example) could be leveraged to support thousands of commercial users more economically than alternative means. The counterargument that I received at the time (later on I'll fetch the urls here in LMT) was that DSL was a residential subscriber technology, and that Ethernet would suffice for business customer distribution anyway, so there was no market for it there. That was three years ago. In a nice way, of course, Dr. Loop (as George is known throughout the industry) put me in my place, so to speak. Well, guess what they now use in the WTC in NYC, and guess how they support it on the back end towards the central office, if the goal is to provision individual broadband services to the desk... especially for power users in the smaller tenant spaces? End Sidebar. Last night, after posting my "on the fly" message again, I received a PM indicating that I look into soft radio, which I'll do after my business affairs are settled later in the day. Could you add anything to this, or explain how soft radio might play into these ideas? And thanks for the reply. I always appreciate getting feedback from you and the other wireless experts in this thread who always demonstrate patience in responding to some of my more hair-brained notions.
