??? Simple question...no bait intended! What's the saying or how does it go? Something about heat and the kitchen...<grin>
Hey, don't be embarrassed about Coppell. It's only a 2MB circuit and so far the VL is keeping up...barely.

Still do! lol Believe me when I say you're preaching to the choir when it comes to Trango. It has been a wild ride UP with the 5800/5830 product and certainly a disappointing DOWNWARD slide with the introduction of yet one miserable Trango product after another. As we predicted Trango has lost its rudder and drifting aimlessly without any apparent direction. This has been very disheartening to witness to say the least. I'm still holding out hope, but not holding my breath. Once the M5830 is gone we'll have moved along to another product. Hopefully that product will be Alvarion VL, but not until the "RF purists" (as they like to call themselves <cough-bullshit-cough>) make a few fundamental changes. Dual polarity and dual band on the fly. I've asked Patrick this question, but it appears the cat's got his tongue! <grin> What's the big deal for Alvarion to add another Atheros radio to the product that will give them dual polarity and dual band capability? Alvarion would rather you have to stock twice the SKUs (V & H SUs) for the ability to change polarity? Not to mention the truck rolls required...this is simply out of the question.

How about Trango Fix ARQ for the 5830-EXT, so it can be like old times, and we can sit and brag on the list how great our networks are? One of the reasons StarOS is becoming such an exciting platform. StarOS can be used as a multi-freq, Multi-polarity on the fly product. I will say that Alvarions choice to not make Dual Freq radios, has allowed them to deliver the highest gain from a radio with good clean filtering of the spectrum range. But nobody has a good excuse for not offering Dual Polarity, there just isn't a negative to it.

However, the VL is also far from being an "end all" solution. The VL has no mechanism to avoid interference (No RX threshold etc.) other than just to retransmit. Also, the VL does not offer the flexibility to change polarities on the fly. In fact Alvarion doesn't even offer an H Polarity SU INT and if you rotate the V Polarity SU to H you'll likely have a water penetration problem. The VL is only available in a 5.3GHz or 5.8GHz solution further limiting the flexibility the product offers. As our HUB sites increase in number and decrease in required coverage area we have found the 5.3GHz band to be VERY valuable. You do not have that flexibility with VL. When Alvarion is presented with the freq and polarity suggestions they simply respond with "we're RF purists" talking points. No indication that maybe, just maybe those would be good features to add to the product. We deployed a VL in an above average noisy environment with the latest v3.x firmware and the results were dismal to say the least. Fortunately upgrading to v4.0 allowed us to salvage the deal, but we still can only pass a few Mbps. This is far less than what a Trango M5830AP can do in a noisy environment. As with most things YMMV.

They are still a viable product in some situations. Alvarion is simply so much better that it warranted this upgrade. Obviously for heavily used links feeding towers to other towns I think Trango multipoint is a bad option. I have not used their Atlas radios which may well do a good job. Trango has been a valuable product for many WISPs over the years (including myself until recently). I have found though that for my applications in feeding other towers to rural towns Alvarion VL works 100% better than Trango or anything else I have ever used. If you have a need for a low-cost short haul or CPE solution then I am guessing that the Trango multipoint radios will still provide excellent service. Just because I have soured on them does not mean they are not a platform for WISPs to consider.
