Dustin, thanks for the encouraging support of my efforts. Since we have been hired for part of this project, I believe it is my RESPONSIBILITY to point out any known issues to the customer; and, it is my responsibility to back up my concerns with hard date, not just 'my feelings.' In the event that the data doesn't show what I know to be in the area, I will at lease be on record for making them aware of other 5Ghz RF in the overlapping areas.
I am interested in any information that you are willing to supply for my education. Again, thanks for all of the feedback and discussion in my topic. - Cliff -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Dustin Jurman Sent: Friday, February 10, 2006 9:42 AM To: 'WISPA General List' Subject: RE: [WISPA] Flawed Spectrum Analysis (I think!) Takes no more than a few minutes to perform a peak hold Bob, maybe you should get one and play with it a bit. It's a very powerful tool and I think your opinion will change. I agree that we have two different schools of thought. 1. Plan the play, play the plan. 2. Show up for the game. Cliff was doing the right thing by doing a spectrum analysis, esp knowing that he was going to go trough some existing equipment. Anything short of that would be irresponsible. I would say to Cliff that if they cannot produce results from the analyzer, graphs and charts than it's worthless and done improperly, just because you have an analyzer doesn't mean you know how to use it. If it's helpful I will post some shots to a website if Cliff thinks that it is helpful.

I am saying to make sure you have ample power and gain to supply a solid signal. Running at -78 on a link is not a solid signal in my mind. We only use equipment where we can control the power. We don't run full bore unlike alot of WISP operators. We don't plug radios like Motorola Canopy units into omni's. And my opinion is if I blow that guy off the air, so be it. It was not properly engineered to begin with. It was finacially engineered to get by cheap. >If the customer wants a quality shot then there should be no >problem doing a spectrum analysis, freq decision and installation shortly >after. > > But the point is moot if Johnny O comes along on your channel tomorrow and blows you off the air (I am only using him as an example). Then the customer is all pissy because he spent money for spectrum analysis that was totally moot. >I agree it's only good for a certain amount of time, but if the customer >wants a reliable shot then due diligence is better than chance luck. > > I don't think a properly engineered link is chance luck. We don't just pick a channel out of thin air and go with it. Alot of engineering goes into it. Spectrum analysis is just not a factor 99.999 percent of the time. -B- >Dustin > > -- Bob Moldashel Lakeland Communications, Inc.
