I still do not understand why 3.65 GHz = NLOS. We are using it very successfully for LOS. That does mean however that anyone who comes into this area expecting –110 noise floors will probably be disappointed. Things should be better however once 3550-3650 and PALs become available.
Same as in any other band, trees close to the subscriber seem to be the worst. And here in the midwest, that’s where a lot of the trees are. Miles of cropland, and then 3 rows of trees next to the house.

SM+reflector 40' up my tower. One very large maple tree about 100 feet away directly in the path. The AP is almost exactly a mile away at 230 feet on a regular Cambium "90" degree sector. I have about -57dBm. I get about -65dBm when the tree is wet. I get 8X/8X in both cases. Uplink might drop to 6X sometimes. Bare SM only got about -72 and I said screw that.

Cambium 450 3.65ghz can go thru a tree or two at close range (less than 1 mile). But it only modulates at 1x mimo-a Telrad lte is able to blast thru a thicket of trees no problem. We've been decommissioning our 450 3.65ghz and replacing with telrad. 2cents -Sean On Sunday, October 25, 2015, Adam Moffett <[email protected]> wrote: Sean, You have the Compact wimax right? I'm curious how you'd rate that side by side with the PMP450 in 3.65. Cambium sales said the Compact would give you better NLOS, but where the 450 connected it would be faster. Would you say that was accurate? Thanks, Adam Nothing really. We tried a few and found either a bare SM or SM+dish was the best solution. Everything else was a PITA because the pig tails that come with the SM are too short, so you either need to do surgery and replace the cables or put the SM in an odd location/orientation to get it connected (if you can find one) 2cents -Sean On Sunday, October 25, 2015, Paul McCall <[email protected]> wrote: What has been found as a successful option for attaching to the connectorized 3.65 SMs?
