One thing I experienced with 3.65 GHz WiMAX was an install that turned out to work only because of signal bouncing off the tall tree leaves, and stopped working in November when the leaves went away. We should have been suspicious when aligning for best signal actually had the CPE pointed up at about a 30 degree angle.
I have seen something similar with 900 MHz. From: TJ Trout Sent: Saturday, June 13, 2015 8:15 PM To: [email protected] Subject: Re: [AFMUG] Do you want to see this stuff here? How does LTE penetrate hills? This is the second or third "through a hill" story in the last week? On Sat, Jun 13, 2015 at 3:50 PM, Patrick Leary <[email protected]> wrote: RSRP, it is a measurement. It is a truer number than RSSI, which is only an estimate (so I'm told). As Ken said, basically add 30 to get an idea of the RSSI value.

Notice that is -108 CINR, not RSSI, like the numbers we're all used to.

Patrick, I haven't been following Telrad but that's too incredible - I can't see how -108, which is below the noise floor for any reasonable channel bandwidth (20mhz+?) could get any reasonable speed, much less those.
