Jon, Sigh...Sync in wimax is the preferred method for small channel deployments to ensure QOS and protecting a scheduled mac that has not been optimized for interference rejection. I would also conclude that mobility and denser cell sites for voip and indoor installs are quite different than most UL deployments. Sync has very little to do with using an old modulation technique that needs sync to ensure scale of any size. I would argue that megabits per Hz, voip, and video are the things to watch for 2007 and beyond. For further information on sync and wimax in the UL bands keep your eye on 802.16h.
I would add that if you can't connect a customer because of LOS issues all the sync you can muster doesn't make a difference. Connecting those customers and saving money on the number of cell sites, leases, and maintenance of those sites DOES make a MAJOR difference as well as WHAT you can sell to your customers in the form of additional services other than just data! A well respected ISP just did a bakeoff in a metro area and they found out very quickly that VL connected more subscriber sites at much higher data rates. I had an engineer on the ground doing 6 meg's up and down where Mot had zero connectivity at 6 of the 11 sites that were the problem areas. As far as your statement of having "happy" customers, Marty from Roadstar already answered that one and please keep in mind that probably very few Alvarion shops are subscribers here (I'm trying to change that because I think it's very important that you guys hear more from our installed base). Maybe Marty and others will chime in on their low maintenance and ease of install and the support we offer. I know Marty is saving boatloads of money on the backend because of his change of manufacturer. BTW, The 2,400 cpe 5 square mile network I spoke of in a previous post is humming right along and could have never been built at the same cost with Mot (and they lost the bid because of that). As a side note: Many of my customers tell me that they just don't get all the Alvarion dissing that has become commonplace on the lists. Look at this current thread and how it has spun into something other than what was intended.....One situation from one installation set the tone for the dissing while at the same time we have a multitude of trained and certified VAR's and wisp's that have had the exact opposite opinion and are doing the exact installs and builds that we're being told can't be done (and several VAR's have done 100's of them). It's a shame we constantly have to defend our position from the constant rhetoric any time there is a congratulating post from one of our customers or someone asking for insight on the value of an Alvarion rollout.......Brad Larson -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jon Langeler Sent: Wednesday, December 27, 2006 7:05 AM To: WISPA General List Subject: Re: [WISPA] Alvarion Comnet Radios have arrived I didn't make any 'claims' and as for 1,000 cpe, that's possible with wifi(although I'd hate to be one of the end-users). Some of the differences is how happy the customers are(reliability seems to play key here), whether they're business or res., how easy it is to have lower cost employees deploy the network(as opposed to me and other "qualified" or "certified" engineers that charge $10K's more/yr), and how tasked the support and management department is, etc. Things that factor into operating a real world wisp. My kind of business is one I can leave for a vacation or another venture while having confidence the thing is going to continue growing while I'm gone. As for GPS sync. Maybe the cellular guys were wrong the whole time, must be another Moto consipiracy and maybe mention that to everyone that developed 802.16d/e(WIMAX) including your own Alvarion engineers! ;) No GPS is not required, but it sure makes a lot of sense and is arguably 'proper' for a multi cell deployment. I predict this is one of those things that the novice wisp will someday either understand, moved on beyond wireless last mile, or stuck it out and trained their support dept. on how to 'put out fires' for as long as possible. Of course all of this is my opinion but I have to go now...hopfully was enough for everyone to chew on ;) Jon Langeler Michwave Tech. Brad Larson wrote: >Jon, LOL.
