Hi Richard, I'm working in this project (a.k.a. WiFiRE or WiLDNET) for the last 6 months. please find my 2 cent inline ------------------------------------------ Dr. Rashid A.

From: richard.h.paine@xxxxxxxxx To: CWater@xxxxxxxxxx; andrew.myles@xxxxxxxxx CC: stds-802-19@xxxxxxxx; WHITESPACE@xxxxxxxxxxxxxxxxx Subject: RE: Article on Intel Long Distance WiFi Date: Wed, 13 May 2009 07:37:49 -0700 I had not checked the date closely enough; my apologies. The subject, however, is very relevant to whitespace and needs to be part of the reflector discussions. The relevance is that 802.11 can presently do what is proposed in Whitespace without the 4W.
<< the project is working in 5.8GHz, so it is outside the TVWS band, It is not politically correct to go against the WiMAX companies that promote it, but it is a fact that 802.11 can do this now and do it very inexpensively.
<< the project mainly put the WiMAX-like MAC layer on top of MadWiFi from Atheros, which degrade the WiFi performance seriously (due to the overhead), compared with the WiMAX throughput, and I don't see any value for it after WiMAX-license excempt come to the picture,
It is so relevant to Whitespace that I am going to be very shocked if the WiFi Alliance doesn’t have a specification as soon as the R&O firms up. The issues that remain for 802.11 are how to use the Whitespace frequencies and the issues around end-to-end security and the database.
Coexistence is relevant, but not necessary in the case of 802.11. Take a look at 19/027r0 for the coexistence use cases and the coexistence matrix. << I agree with this but not in the 4W use cases...

I talked to (one of) the program manager and there was some interest in our products, but I have not heard back yet since that conversation, about a year ago.
If I understood the solution, it was a project from a University that was adopted by Intel as an interesting technology doing almost the same as WiMAX so it is controversial if Intel will let it live alongside their official WiMAX support - probably as long as it stays low key enough. I recognised almost all implemented solutions from my background with Karlnet and our WORP protocols.
Since this has very little to do with Whitespace, we should take it off that server and into private email if you want to discuss it further, unless you can bring it back on topic.

From: whitespace@xxxxxxxx [mailto:whitespace@xxxxxxxx] On Behalf Of Jack Unger Not really. That article is 14 months old and the original announcement came out a year or so before that. When I read the original announcement there was nothing particularly new that struck me in it. WISPs have been providing long-distance services for many, many years. OK; Intel's got a custom MAC layer and TDM. Shucks, we were using Karlnet software with that functionality back in 1994 to do outdoor point-to-multipoint wireless. It's as if Intel never took the time to look around to see what was already out there before they "invented" it. Looks like Intel is making some progress on an inexpensive rural WiFi solution: http://www.fiercemobileit.com/story/intel-extends-wifi-to-60-miles/2008-03-19 Richard Paine Success is getting what you want, happiness is liking what you get!
