You can't make an educated suggestion if there is no spectrum analysis.
You can if you look at the picture he posted, and have any experience co-locating Canopy on a commercial tower. I would certainly move the Canopy as far as practically possible from all that other stuff, and watch where my wires were running in relation to the other equipment, as well.
Don't get me wrong: Do the Spectrum Analysis and if that shows some way to re-arrange the frequencies, rock and roll. But the odds of that being possible, when all AP are having similar issues to clear LOS clients at less than two miles?
Much more likely the problem is proximity to the other stuff on the tower, unless there's some frequency-hopping 2.4GHz backhaul up there that just hasn't been discovered yet.
I got some more pictures of the tower. This thing has quantar repeaters, cell phone equipment, microwave dishes, looks like other backhauls, a TON of rf cabling for multiple repeaters, its pretty clogged.
You know motorola did this install; you’d think they would have known better then to put it right under that huge microwave dish.
SORRY for the overload of information, but I figured the more the better. The above stats are right after I did the SA (5 minutes after), so everything was reset and that is why the reg counts and re-reg counts look low.
One issue I also have is only AP 01 will allow SM’s to register in 2x mode? You can see the SM’s reg’d to AP 03 are extremely close (both have reflectors also) but only register at 1x. Also how come the session status in AP 01 shows more information then the rest of them?
That Spectrum is absolute garbage. There’s no way that’ll work for you.
There has got to be something near by or on that tower using 2.4.
What I’d do next is shut off all the 2.4 Gear you have on the tower, take a 2.4 SM and from the ground point it up at the tower. If you get the same high levels of 2.4 interference, then the problem is with something on the Tower. If you don’t then it’s something else very near by. But my guess is that there is something on the tower using 2.4 that you don’t know about.
We have our own shelter, and there is probably 4 or 5 other shelters, so we can’t just look around for other equipment besides of what is on the tower. Also, ridnet, there is no FCC out where I’m at, so basically its whose more important, if we were able to find who is using the 2.4ghz, we might be able to make them move.
I’m sure there is someone else using 2.4 GHZ on the tower. Do you think any of those microwave dishes could be 2.4 ghz?
I am going to try and get motorola to move it up 30 feet or so. The main problem is I don’t know if they left a service loop in the cable or not.
Before you do anything. Before you install in a tower.
You must do a spectrum analysis of the site.
You might think I’m crazy but that tower is not very populated. You should see one of my installations.
5.2Ghz is better, 5.4GHz is much better because not many people are using it at this time, 5.8GHz is more like 2.4GHz, a prostituted band, that will also happen to 5.2 and 5.4. Fact is, If it’s free and very little regulation then it’s a problem. FCC will not help on this band.
Again, before purchasing the equipment do a spectrum analysis of site. Check all in the tower, ask if necessary. You are lucky that Canopy equipment have spectrum analyzer built in, Don’t know of any low cost equipment in the 802.11 industry that does.
What’s next to the 60MB BH? Brand, picture of the back?
When you say “If we were able to find who is using the 2.4ghz, we might be able to make them move.” Was your system working before? Else They where first and you have to move.
well, I totally agree with what you are saying. That is why we paid motorola over 220K to deploy this system. They should have done the SA on the site and figured all this out.
I am going to hold their feet to the fire and try and make them swap it out with 5.4 ghz radios, and move the cluster. But it will not be easy.
So I need to ask motorola to climb the tower and do a spectrum analysis for the 5.4 GHZ band, correct?
I most definetly would guess that the 2.4 band is being used by a Tsunami 2.4 Telco System, the take up all the band.
Second, I see your cluster with 5 -6 Aps, some Aps are shooting at the tower, even if you had clean spectrum, that would be problematic with fresnel issues. You must split that cluster into 3 unit cluster, and install the other 3 units in the opposite side of the tower.
Third, I dondt really think Motorola Corporate was in charge of this install, I assume probably a Motorola Authorized dealer or something similar. (Motorola dont usually install systems for customers) So the 200k was spend on this site alone?
Where are you located, check the local spectrum authority to verify unlicensed availability
The Tsunami are Microvawe Radios that the Cellular and Telco Companies use to backhaul T-1’s.
They operate in unlicensed bands ( 2.4 and 5.8 ) and the channel sizes they use are very broad 40 - 80 mhz.
This links are always engineered to have a very high signal margin to overcome interference problems, so probably one of the big dishes on the tower is a 2.4 link.
This radios have been around for a long time, they were first made by Glanayre, then they were spinned off as Western Multiplex and finally bought by Proxim.
I would be thinking of using another band ASAP, check if 5.4 is available on your area. Also I would use The Aps from www.lastmilegear.com
The are Motorla Canopy authorized units with better antennas.
