Well, let me ask this. Are you doing 2x2 or 4x4 on the Telrad? Obviously
4x4 would give a slight advantage.
My whole thing is, OK, it might work through a shit ton of trees. Linked
up and able to move some traffic is one thing. But a whole bunch of low
modulation customers on a sector is not worth the investment. LTE,
Wimax, 450i 900.. whatever it may be.
I know of a Telrad installation where they couldn't make it work. Turned
out to be interference. They had some guys from Israel come "fix" it. I
won't say any names, but I now see what they did to get it working. It's
in the 3.5 band.. because I can see them on my 450's spectrum analyzer.
From multiple sectors on multiple towers, so I know what direction it's
coming from. And I have no doubt they're running it over powered.
Welp, we have a BaiCells demo kit, so we'll see what happens.

We've had Telrad Compact 1000's for around 2.5 years, but they're
running Wimax firmware because we were replacing older 16e
installations. We have a number of sites now that have entirely dual
mode CPE so we're about to pull the trigger on LTE. We're installing
four LTE base stations next week on brand new sites, and assuming
those go well we'll upgrade some existing Wimax sites.
So yeah, within the next few weeks I'll know more. I'll definitely
report back.
It's interesting that you phrase it as "if it works at all." The issue
with Wimax has never been it "working", it's just that it comes with a
lot of quirks and it sucks at administration and troubleshooting. I'm
speaking of Wimax in general here, not Telrad specifically....and I've
used Wimax from three different vendors now. I have no fear about LTE
working. I _am_ afraid it will turn out to be cut from the same cloth
as Wimax.

Aren't you doing Telrad? Please let us know if it works at all.

I wonder what LTE would do with the same RSSI.

Oh I also have somebody with a -88 who gets about half that.
900 was the last ditch effort for both of these.
With wimax from the same tower we got a big fat nothing at both
locations.

On the other end of the quality spectrum:

19 6.07 Mbps 1.32 Mbps 7.39 Mbps, 474 pps 821 (410 pps)

That's a -85 on a 5mhz channel. On any wider channel I lose this guy.

We're looking at doing a forklift on a couple of 900 MHz FSK

The places we are looking at do not have Smart Meter issues.
