We tried out our Telrad LTE the other day. LOS from 4 miles was -88dbm
RSRP (which would be similar to -57 RSSI). Naturally we maxed out the
speed at that spot. The guy moved a hundred yards or so to
intentionally put some woods in the way. Through about a hundred foot
thick stand of trees we dropped to -113 RSRP (-82 RSSI). That gave us
5.5 to 6.0 mbps on a 5mhz channel.
Subsequent test locations gave us similar results.
This isn't bad. It's not magically piercing through the trees as some
sales people might lead you to believe, but it does do two things:
1) It functions (at lower and lower rates) all the way down to the noise
floor and a little under it.
2) You get relatively good performance with a relatively weak CINR.
What I mean here is that your wifi type thing (UBNT/ePMP) probably has a
lot of packet loss and inconsistent throughput when you have a CINR of
10, whereas LTE with CINR 10 actually seems pretty stable.
So yeah Ken, I guess I'm telling you what you already suspected. You
might be happy if you need to get through 50' to 100' of foliage. If
you need to go a mile through the woods you are still looking for
900mhz.

So far we're seeing no better than about -88 RSRP. Most places we
tested was right around -100. All Non-LOS. Very Non-LOS. Within a mile.
And the nitwits didn't get my memo that I wanted to collect CINRs and
mod rates too. They were able to still get about 7Mbps down (less than
50kbps up tho) with about a -115 RSRP. And I did double check that
we're not exceeding the 1W/MHz EIRP cap. We're going to do some more
testing tomorrow.

I hope it works for you through the solid mile of trees, I’m skeptical
though. It seems to me like a golfer trying every new brand of club
and ball that comes out hoping to find one that goes straight through
a mile of trees to the green. You may get incremental improvement,
but I know people in that situation whose cellphones don’t work.

I haven't changed or turned on anything new facing you. And I don't do
alternate freqs on the 450's even though sometimes LBT goes to hell.
Things have really calmed down since moving the entire 450 network
from 13.2.1 to 14.1.2 though.
We are going to be testing a Baicell tomorrow in an isolated area and
not even facing you. Just FYI. I have it down in the lower half of the
band to step on the UBNT shit which I don't really care about anyway.
A straight mile deep trees, so I doubt we'll even see it on any other
sectors.

Ive been beating the hell out of my network this last week with the
320 going to shit. The UBNT 3ghz hasnt gotten any worse that it was
I went as far as shutting down the majority of the 3 ghz to get
spectrums. Went through and coordinated the network based on those. i
added QOS profiles with harq, it got me management of most of the
CPEs, the customer experience is deplorable, theyre all probably
trump supporters.
Im going to let this sit for a few more days to see if Im just
fighting the atmosphere. If it doesnt resolve, Ill need to hail mary
and expert for a paid gig to get on my network with me for a few
hours one evening soon and put into words for my boss just why it is
he should not hire incompetent boobs like me to run his network, and
hopefully offer some advice on how i can save face.
im getting in a bunch of packetflux so all the 320 is synced (there
are a few outliers that never got sync as other projects took
priority and I have a couple base units that lost communication with
the syncinjectors. I figure if I get everything on the same sync
product I unsure theres not some diode between manufacturer products
offsetting the puls by a few nanoseconds.
I see a forklift in the near term of ubnt 3ghz to epmp 5ghz to free
up spectrum for 450, which i assume will destroy the remaining 320.
