Re: [WISPA] 5.8GHz Link Loss
Scintillation effects cause the radio signals to be refracted. Scintillation is a real world concern for those building microwave links *ESPECIALLY* if the scintillation off of a warm surface is in the fresnel zone of the link, like in my install over a flat roof. The dish was at least 10 feet off the surface of that roof, but shooting over probably 300 feet of flat rubber membrane. Scintillation every afternoon trashed the link until we raised the dish a few feet.

Re: [WISPA] Direct Lightning Strikes
Yes, we use DC ground antennas. I am going to move the ground wire from the XR2 to the case instead of the Board standoff screw. Someone said the RB411 has a weird ground arrangement and that may be part of it. I have not been grounding the case either. Sounds like I need to act like the satellite guys. They ground everything no matter how far up the building the wire has to run.

Re: [WISPA] 5.8GHz Link Loss
Ha! I looked up scintillation as well and was wondering the same thing. Odds are Mike hit it on the head with the RF thermal ducting suggestion. We've seen this on long paths (20miles+) that have little down tilt. The RF signal can be ducted away from the intended target as it gets caught between thermal layers in the atmosphere. Paths with more down tilt between point A and point B appear to be more resilient to RF thermal ducting. I can only assume this is because the RF signal has a better chance of pushing through the thermal duct "wall" err I mean ceiling & floor. Long paths engineered with enough fade margin will typically stay up, but may downshift in modulation to compensate for the reduced signal strength. This is why it is important to eek out every last db of signal when first installing long PtP paths.

Re: [WISPA] 5.8GHz Link Loss
Recently we had a tropospheric ducting episode which affected ever 2.4 p2mp customers. There was a layer of warmer air actually trapped by a layer of cooler air. This junction looks like a mirror to radio waves and can be steered or bounced quite a bit off target. When I built microwave links in S FL that had to be very reliable, we engineered for space diversity. One 22 mile link at 6GHz used pairs of dishes with 30' separation. It would switch many times in a year, and during tropo events, several times in one night. Gulf areas are more apt to see tropo events. Here in the midwest they are uncommon. This may not be the case with your link, but is worth learning about. Here is a nice site for tropo predictions. http://www.dxinfocentre.com/tropo_car.html Mike At 10:33 PM 8/7/2009, you wrote: >So, what causes this crazy loss on all of my 'longer' 5.8 links after >dark/overnight?

Re: [WISPA] 5.8GHz Link Loss
We're seeing almost exactly the same thing on one of our 5.8GHz VL links (could be PTMP but at the moment is just PTP) a little north of NYC. We know we have a multipath issue at the site to begin with, and the fresnel zone is just grazing some trees. I suspect that the humidity / temp combination is causing some distortion of the fresnel zone with respect to the trees. In our case, the environmental changes may be impacting the multipath as well. Tricky to troubleshoot. Here's a note from a list member from a year or so ago that may be relevant: /What is actually happening is the K value of the path is changing when you get hot air under cool dense air. The normal value of refraction (ie K) is 4/3 and approaches 2 on coastal areas. Well when you have a link where K goes down to 2/3 or less it causes the earth profile to "bulge" out and obstruct the path. This with decoupling (only an issue with high gain antennas) where the angle of the incoming wave is greater then the beam width of the antenna feed will cause outage. At this distance you should be running at a 33 or so SNR with no interference. Now when the signal fades you loose your signal and have to compete even more with the interfering signal. might want to try another polarization and HP antennas./ Thanks, Adam On 8/8/2009 7:59 AM, Joe Miller wrote: > Ed, > > Are these PTP or PTMP links?

They are planning to offer Canopy type functionality at Ubiquity prices. They said no PS though, so I suspect they have something else in mind to replace that. Regards Michael Baird "optional polling" This will be real nice. I wonder if the will do it for all the NS and PS series? Scottie -- Original Message -- From: Michael Baird Reply-To: WISPA General List Date: Thu, 06 Aug 2009 09:34:35 -0400 They are supposed to explain the extra features in a press release this weekend. >From the forums it appears they are going to impliment optional polling on their BulletM series w/cpe's to follow, other differences would be the single stream 802.11n, and a much beefier CPU for more users per sector in the 802.11b/g modes vs the normal bullet, and higher real TCP throughput for the backhauls. Regards Michael Baird Would you mind sharing the FCC id? UBNT claims it is different than the regular bullet, but doesn't share it, and I don't see it on the FCC oet website search. If it's the same as the bullet, you'll only be able to use the 5745 and up freq band.

The selections are : 5180 to 5320 in 20 meg increments. 5745 to 5805 in 20 meg increments but it also has: 5500 to 5680 in 20 meg increments. Is this unlicensed spectrum? I thought 5400 was, but didn't think 5500 to 5680 was. Thanks, Tim Kerns CV-Access, Inc. WISPA Wants You!

[WISPA] Tranzeo 900 Latency
Took the day off to go for a Bike ride.. The actual software build is TR6-4.0.3Rt - Original Message - From: John Scrivner To: thic...@rockies.net Sent: Friday, August 07, 2009 12:40 PM Subject: Fwd: [WISPA] Tranzeo 900 Latency What firmware version is that? Is it 4.02 or 4.03? Thanks, Scriv -- Forwarded message -- From: Terry Hickey Date: Fri, Aug 7, 2009 at 10:56 AM Subject: Re: [WISPA] Tranzeo 900 Latency To: WISPA General List John Tranzeo released a new firmware update the other day that has helped my 900 system a lot. Better signal and much faster pings. I have been fighting the same problem as you for the past couple of months.
