We took great care to inspect the antenna mount to the pole, because we mounted to less than 4" dia pole, and wanted to make sure it was secure for long term. But we forgot to inspect the mounts holding the pole to the super structure. And as it turned out, it was the pole itself that moved.

Re: [WISPA] Trango Giga Problem
Hey Travis, Interesting information regarding the Apex. I assumed it only had the PoE port and the SFP port. So, are you saying it has two PoE ports and the SFP port? I guess I need a copy of the Apex manual as well and do some reading. Go ahead and send it to me if you have it handy. We've got four Apex's coming and another 6GHz Giga on the way. Hopefully John will get them to us by end of next week. Agreed the Apex looks to be a nice radio.we were attracted to the slightly higher throughput numbers the Apex claims over the Giga, but there are still many cases where the Giga makes a lot more sense due to the flexibility the Giga IDU offers. We're very happy Trango offers both products.

Re: [WISPA] Trango Giga Problem
Have to disagree with Tom's advice here. It is never a good idea to briefly/temporarily change channels within a licensed band without consulting a qualified frequency coordinator. We did consider interference as a possibility once upon a time, but consulted with our frequency coordinator before trying a different channel plan. Only after indentifying a second available freq pair did we change channels briefly/temporarily just to see if interference was the issue. It was not. While interference is possible in the licensed bands it will most likely be caused by someone "briefly/temporarily" changing channels when they shouldn't. You can also simply turn off the transmitter on the far side and view RSSI readings. If they show higher than what your expected noise floor should be then you might have an interfering source to hunt down. Simply changing channels at will briefly or otherwise within licensed bands should never be attempted.

We'll do this by adjusting your power levels, targetrssi and cableloss settings. What does your path analysis show your expected RSSI should be and at what power level? I assume this link has production traffic running across it and can't be taken offline?

Re: [WISPA] Trango Giga Problem
Gino, Looks to me like you are running a little hot. You want the MSE to be -32 or better I would try turning the power down on each side 1db at a time until you get the best MSE (on the remote side) while still having the best signal. We had to turn one of our links down to +12 to get the best MSE, while still having a -40 signal.

Re: [WISPA] Trango Giga Problem
Not necessarily true with high frequency or millimeter microwave gear. Due to large fade issues inherent with higher frequencies it is not uncommon to engineer a link with -35 RSSI levels. I believe the Giga is safe down to -25 RSSI or thereabouts. However the higher the modulation rate the "less hot" you can run it.
