RSRP is how LTE systems measure signal. I don't believe it's an
intentional skewing on Telrad's part, but I'm sure it leads to plenty of
misunderstandings.
My experience over time has been that every vendor says their stuff
works NLOS. They can say that because they all DO work NLOS depending
on how strictly you define "working". I do believe that Telrad LTE
works better than average at NLOS, but yeah I don't believe it would
work everywhere, and I hope nobody believes that it makes extra signal
power appear out of nowhere simply by being LTE.
I'm actually more worried about...well...everything else. There's so
much focus on their NLOS claims that I think it has drowned out other
discussion on the product. For example:
* Is anyone else bothered that there is no documentation?
* Is anyone else bothered that the Gemtek CPE provides no status or
control of the ethernet port?
* Has anyone else had the CPE lose configuration values after a
firmware update (like the Wimax channel scan table and radius
username, which you can't fix without a damn truckroll)?
* Has anyone else had to RMA BTS's that weren't particularly old? I
had two with RH alarms that were each less than a year old. One
with a corrupt file system after 3 days in the field.
* Has anyone had success using the ACS for automatic firmware updates
of CPE? Ours download the firmware, then lose contact with the
server until they're rebooted (through the web GUI, or power plug).
After a reboot they do have the new firmware version, but it's no
help if I have to touch them all.
* Anyone had tech support issues? They've closed our ticket about the
ACS issue TWICE. Both times saying, "Oh sorry, we thought that was
working now." This has been an ongoing investigation since September
by the way.
* Is anyone else troubled by the small MTU (max is 1480 I think)?
I have tons of other complaints that are specific to the wimax
firmware. Are we so impressed by NLOS that we don't need to discuss
whether it's good at anything else?

If you expect LTE 3ghz to be the silver NLOS bullet it is not.
Putting speeds aside for the moment. Lets just talk signal. Same
tower, same height Telrad 3ghz LTE with the Alpha dual-slant sector
within 1db signal as 2.4 NBM2 on a UBNT 10db omni.
LTE does not change physics. The sales guys want you to believe that.
It ain't so.
So, if you can attain a -75 on a 2.4 omni on a tower it won't work
worth anything. That same signal on LTE will rock.
If you think it was have equal penetration to 900mhz and be a
replacement for your old FSK system, you are sorely mistaken.
Near line of site? Yes.
We had a very specific application that Patrick said without question
would work. When it didn't it was a bad antenna, then it was bad
jumpers, then it was a bad compact, finally they flew someone in who
argued with it for a day and at the end of the day? You can't argue
with physics.
The whole "watch it work at -110" is garbage too. They skewed the
numbers by 30db. Yes, it will work at -80, will it work well? YMMV.
In the end it was too expensive for the limited benefits we observed.
They swear I'm the only one in the world it didn't work for in the
same breath they swore it would work without any doubt.

Ditto. Hell, onlist would be fine too. I'm sure many of us would like

Hate being a decision maker sometimes.
Love the cambium pmp450 roadmap. I know several people
are using pmp450 in 3.65 and it works. I also see now
that a panel antenna is available based on the 450i in 3.65
I may have fallen in love with lte. Haven't seen the
telrad talk yet. Hear the new vendor does lte for roughly
what we started our 900 network for back in 2004.
Why would I choose lte over cambium ?
Would I? I think the cambium pmp450 (in 3.65) has a
better roadmap....one gig aps by like 2017.....
What if I choose the wrong product?
Convince me.....

450i is backwards compatible with 450 today.
