Hello Scott, Yes, the links will work great until you have a heavy rain. Talk to Travis about the 38GHz links he has running at several miles with great uptime. Great uptime because he's nearly running them in a vacuum environment...IMO! lol Unfortunately you and I do not enjoy such an RF friendly environment for our paths.
Right now most of our 11GHz links are Trango GigaLINK which are the split architecture design (we required coax runs) and may not be as powerful as the Apex. We have a few Apex 11GHz links up and they do seem to perform better, but none of them are as long as some of our GigaLINK paths. The Apex also has a much better "hitless" modulation shift than the Giga, so your overall experience during rain fade events will be better with an Apex than a Giga. Agreed, our sites have alternate paths to fail to during rain fade or in the event of equipment failure. However, there is still a momentary drop in service and we strive for as close to 100% availability as possible. With the proliferation of VoIP running across our network our clients demand it! Four nines always sounds great and looks great on paper, but it never seems to occur when no one is watching! That hour of estimated downtime is always at the worst time. <grin> I'm happy to offer any additional help with your Trango gear offlist if you want to bounce configuration or other specific questions that may come up.

Hey Brad... I'm not familiar with this gear (or any at 11Ghz). Trango ran the analysis and came back with 4 9's for the link. There was about 35db rain fade margin at 100Mb rate. I assume maybe a problem in a torrential downpour but will a good ole regular rain take the link out? I've got burstable bandwidth that can cutover when / if the link goes down on 95th percentile usage so if it doesn't happen often it shouldn't be noticed or matter. Just want to get the 100Mb from the other city when available cause its less expensive. I'm actually considering two back-to-back apex links 18 mile hop on first one and 25 mile hop on next one. Numbers look good on the link path analysis not considering rain.... (all the 11gig links have 4ft 40db antennas spec'd) Scott Carullo Brevard Wireless 321-205-1100 x102 ---------------------------------------- From: "Brad Belton" <b...@belwave.com> Sent: Tuesday, April 20, 2010 9:56 AM To: "WISPA General List" <wireless@wispa.org> Subject: Re: [WISPA] Best Backhaul link 11Ghz 20 miles @ 100MB? Ceragon is great gear, but a good bit more expensive than Trango Apex. 11Ghz will easily rain fade at 20miles in our K or M rain zone. We have 14mile 11GHz links that have faded with rain I can't imagine Florida with a N rain zone (the worst rain zone in N America) will be a good place for a long 11Ghz path much less 20 mile path! I guess it just depends on what level of availability your path requires.
