No I mean they're on the back of a turtle who only has one flipper left and 
blind in one eye.  Still no ETA.

      Or if all wireless inside use E400 from Cnpilot line.

            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.

            can you set up some 900 test shots?

            So given this scenario, would 2.4GHz be better?  I can use 5GHz

            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 ;-)

            The length of the needles matter.

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