Seems that manufactures and the software developers are not on the same
page. They are both trying to
one up each other on trying to make setup completely hands free. They
need to just have a simple gui and roll
with it and quit trying to become a master domain and take over my laptop.

I discovered yesterday I had to disable “Bluetooth Collaboration” on
the WiFi card in a new laptop for it to even pair with a Bluetooth
mouse. That seems counter intuitive. Seems like a collaboration
feature should make them play nice, not fight to the death.

Also trying to get a good signal in the far reaches of some houses can
be a lot more challenging at 5 GHz than 2.4 GHz.

Until customers complain their stuff doesn't work, a lot of cheap
laptops, tablets and many low to mid range android phones are 2.4 only.

I should add that in a typical environment with wood frame
houses/other structures, it helps a lot to choose the 2.4 GHz channel
on the home WiFi AP for each CPE location, so that none of them
overlap with your carefully predetermined 10 MHz channel.

2.4 in 10 MHz channels goes through a decent amount of trees within
1-2 miles max, if all the CPEs are nanobridge m5-25 dishes or similar
sized reflectors...
I've seen such setups with clients in trees and signals right around
-69 on both chains.
Not a lot of aggregate capacity per sector however.

I've never had any luck with 2.4 going through much more than the side
of an aspen tree.
can you set up some 900 test shots?

I have not measured one, but if someone has a pine tree nearby and an
ohm meter, measure the resistance of the needle. Make sure you jam
the probe into the interior of the thing.
I am guessing that the water content of the needle absorbs some of the
RF energy al la a microwave oven. But anecdotal evidence over the
past 10-15 years has shown that pine trees are worse than others so if
the needle itself has a fairly low resistance, like 100 ohms, it is
acting like a dipole with a termination resistor. That is really
going to suck up the signal.
Stealth aircraft have microwave absorbing foam on some of their
surfaces that operate by similar principles.

the wavelength of 900Mhz is ~33.3cm so a quarter wave length is
~8.33cm (~3 1/4 inch). Ponderosa pine needles (and many other pine
needles) are around the same 3 1/4 inch length
https://en.wikipedia.org/wiki/Pinus_ponderosa
so with water in the needles you have a big 900Mhz RF
scattering/reflector ;-)

Realistically, what kind of distances do you get through these types
of trees?
