[WISPA] TrangoLink45 Link Problem
I have a 2 mile link with TrangoLink45's. Clear line of sight. The MU transmits at 54Mbps all the time. The RU drops to 12Mbps within about 2 minutes of setting it to 54. This morning we tried 6 or 7 different channels. All had the same RSSI of -61 or -62. All behaved the same way. What else should I be looking for to keep the RU sending at 54? Of course the customer receive side is the one that is slow and this link services about 60% of the customers. -- Scott Reed Sr. Systems Engineer GAB Midwest 1-800-363-1544 x4000 Cell: 260-273-7239 WISPA Wants You!

Re: [WISPA] TrangoLink45 Link Problem
Only a -61 at 2 miles? What antennas and at what power level?

Auto power adjust is set to -60, I think, so it is right on. Brad Belton wrote: Only a -61 at 2 miles? What antennas and at what power level?

Re: [WISPA] TrangoLink45 Link Problem
Ok, that makes more sense. Do you have a spare link to swap in place? I'm not leaning towards interference if you've tried several different channels all with the same result. It's been a long time since I've used an UL Trango PtP, so maybe someone here a little more fresh with the gear will chime in with more detailed suggestions. What is Trango support suggesting?

Re: [WISPA] TrangoLink45 Link Problem
Did you try any of the 5.2 channels? I have an 11mi link where the su modulates down to 24mbps looking up at the tower. Switched to 5300 and even with the reduction of power, it will modulate at 36mbps. At two miles I would think you would see similar or better results Sent Mobile Jerry Richardson airCloud Communications On Jan 8, 2010, at 6:15 AM, Scott Reed scottr...@onlyinternet.net wrote: I have a 2 mile link with TrangoLink45's.

Re: [WISPA] TrangoLink45 Link Problem
, until you get the desired rssi, then use Trango's BUdget Calculator and confirm it matches the results. If calcs match, its most likely aligned good enough. So in summary, it probably is noise. Hardset config, no auto anything. Rely on Survey and Linktest commands to Diagnose. I'm not saying its not OK to use Auto on an ongoing basis. Just definately disable it during the troubleshooting process, so you have controlled factors to compare. .

Re: [WISPA] TrangoLink45 Link Problem
remote diag, and learned all we needed to do is realign. One of the ways to partially test alignment remotely is to match RSSI with LinkBudget. Again, autopowerlevels, can mislead you, so turn it off. Manually reduce the power level, until you get the desired rssi, then use Trango's BUdget Calculator and confirm it matches the results.
