Matt, I agree with almost everything you said... except the polling part. Having a robust, efficient polling system is the best thing available for outdoor wireless. That is one of the main reasons we are now using Mikrotik is because of their Nstreme and polling system. We are finding now it's not the same quality as Trango's polling, but it does work. How else do you keep a single customer from taking down an entire AP with a large upload (usually from an infection, virus, worm, etc.)? I have tested this over and over and over, and every time I come back to the same conclusion... you have to have a polling system to control the upload, otherwise the customer with the best signal dominates the AP (on the upload side). Here is a very simple test... set up an AP with two connected clients without polling. Start an upload on one client and then try doing a download or even a ping from the 2nd client. My tests show the download and/or ping to be very unreliable and very sporadic. Now, if you turn polling on and do the same test, everything works fine while the upload is running and the 2nd client can't even tell there is an upload running. What we really need is the Nanostation-ROS... a Nanostation running Mikrotik (even for $50 more per unit)... that would be the killer CPE... I would place an order for 500 right now today. :) Travis Microserv Matt Larsen - Lists wrote: Hi Travis, I'm with you - the Nanostations are a pretty amazing product. I've been deploying Nanostations on 10mhz channels in 2.4 and 5ghz with StarOS access points and the performance/interference resistance is pretty amazing at ANY price point. I could say the same thing for the newer Tranzeo CPE units as well, but they can't match up with the Ubiquity price point just yet.It is neat to see a product with many of the Canopy advantages (rich features, small footprint, inexpensive to produce, good interference resistance) that is compatible with the 802.11a/b/g standards and thus able to take advantage of the very innovative Mikrotik and StarOS platforms. I'm curious to see if someone comes up with a good reflector for the Nanostation radios. That would enable the use of the adaptive antenna mode, and since StarOS has the ability to switch connectors on the fly - and potentially polarity if hooked up to a dual-pol antenna - you would end up with a standards based product that would have nearly every feature that the Trangos had that made them special (noise threshold at the AP, software switchable polarity, site survey, etc). No polling, but that is one of the most overrated features anyway. Matt Larsen vistabeam.com Travis Johnson wrote: |
