Hello Cameron, As good as Alvarion gear is or may be, it is still best effort gear and not committed rate. Many factors will play into what an end user will actually be able to produce across Alvarion gear.
If you are looking for a committed rate backhaul you need to look at the Trango GigaLINK gear again. Completely different class of hardware than the VL backhaul products. Yes, it will cost more, but the saying holds true; you get what you pay for. Your 3mile link is a cake walk for 18GHz and if you have the tower space for 6' antennas the 6GHz GigaLINK is perfect for your 20 mile link. BTW Ralph, our tests on the bench with VL between two MikroTik 3GHz routers was decent in HDX. Problem we saw was went you started pushing data heavily in both directions the link all but fell apart. Not what you need to have happen on a critical backhaul. <grin> Best, Brad -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of ralph Sent: Sunday, December 09, 2007 11:12 PM To: 'WISPA General List' Subject: RE: [WISPA] Wireless Backhaul options/test/results Funny you should ask. I tested a B-100 going 500 feet with Qcheck a couple of days ago and got only 38 Mb. I'm not sure if Qcheck reads out correctly or if I have to double it- I was in a hurry. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Sunday, December 09, 2007 11:12 PM To: wireless@wispa.org Subject: [WISPA] Wireless Backhaul options/test/results Hello all, I am in the need of upgrading some backhauls. We are currently using Alvarion AUVL units with a SU-54-BD. According to Alvarion, this link is only capable of 16mbit each way (Alvarion, please call it a 32mbit radio.) We have looked into results on users who use Alvarion B100, Trango Link 45, etc.. We are open to all options...As long is it works very well. The link is about 3 miles, but we have another link that is causing the need for the upgrade that is about 20 miles. Trango has licensed gear in the 6ghz and 18ghz line that is very impressive, but just too expensive for us right now. I would like to know if people are using B100 what is the up/down max throughput that you have seen? 50/50? etc.. Are you running VoIP over this? Alvarion claims 1000 concurrent calls over this link, i'm sure many of you have not even dented this number. I am growing to be a big fan of Trango, but have been well, but their packet per seconds is a lot less than Alvarion B gear at almost 40,000 compared to trango at around 10,000. Thanks, I man in dire need of a lot of bandwidth, distance and no spectrum to put it.... -Cameron ---------------------------------------------------------------------------- ---- WISPA Wants You!
