Wireless Joint

Hello all. First post here

So my issues is pretty simple to explain. I have a great signal strength. -65 dBm on average, however my signal quality fluctuates widely, from -10 to -15 which is poor for sure. I am not sure what to do with it. Am I to hot? I have mimo antennas on the roof. 20 foot of LMR to the modem. and this has occurred on usable bands here of 2, 4, and 13. I am not really sure what to do. I have seen this with both Verizon sim and T-mobile.

Youve got some wierd issues.

Your RSSI and RSRQ are way bad. The RSSI isnt something I pay attn to, but your RSRQ is terrible. Its odd that you dont also have a bad SINR reading.

I'm wondering if you have multiple towers with the same bands on each causing crosstalk issues, confusing the signal. No noise, just lots of powerful voices speaking at the same time in the same language.

I certainly am not an expert at this stuff but have some experience. And I agree, I cant make sense of whats going on. I have clear line of site from my roof to any of tower I want to point at. And I am pointing directly at the one that appears to provide the best signal strength. I really don't know what else to try. There are no large bodies of water between me and there, no reflective mountains or anything like that. I just don't get it.

Hello,
Sure there isn't any large metal buildings or structures in the LOS direction? If you look at google maps satellite view.

Nope in fact it is mostly farmland. no other towers in the way or anything. I was curious if the MIMO attenna setup is causing a problem? Does that seem possible to anyone or has anyone experienced that degrading the signal quality over strength?

What kind of Mimo antenna do you have?

I'm guessing by the -40 RSSI that its totally clear LOS and within less than a mile. You could get away with a omni antenna, and not yagis. Try a "worse" antenna and see if it improves. More than likely the 4G modem is getting overloaded by the extremely strong signal and making throughput worse.

What modem are you using??

Hey Guys,. Thanks so much for trying to help. I switched from page plus to simple mobile and its the best change I could have made. No clue why but I have 0 issues now.
