I have not needed to be particularly careful with my TDMA gear so I have previously used Radio Molbile to give me an idea of tilt, but LTE is still causing me grief in 3.65 and I need more aggressive tilt if I'm going to make this kit work.

Can someone validate the equation: https://www.pasternack.com/t-calculator-antenna-downtilt.aspx

H=height

t=transmitter

dt=downtilt

bw=antenna beamwidth (vertical)

Distance=distance from t to r on a horizontal plain at center of the beam

Rad/inner/outer = inner and outer edge of the beam (assume -3dB)

Assuming level ground and given :

t=220 meters

r=10 meters

dt=5

bw=7

=

Cheers,

Ian

Paul,

We are using the 3000 in band 40 in a 10Mhz channel with filters because it is
the WCS band adjacent to Sirius XM.

We see about 34Mbps x 3-6Mbps UL.

If you are in an area with anyone within 50Miles of your band, you really want
to know what they are running and make sure that you are timed via SA and SFF.

I would recommend serious down tilt.  We have gone to 5-7deg with tremendous
performance increases on the uplink.  We were at 3-4deg and had a hard time
getting 4Mbps on uplink, since changing a few sites to more aggressive
tilt...we have seen a serious improvement in uplink. 2Ghz...carries far!.  We
are running SA1 SSF1. Please keep in mind we have only 2 10Mhz channels and are
running 4 sectros back to back with approximately 10KM between tower sites...
so more small cell than Macro.

I just finished picking up another Anritsu BTS Master with FDD LTE options and
I'm going to add the TDD LTE options to it.  It will give me OTA (Over the air)
demodulation showing RB usage, EVM (error vector magnitude) measurements,
constellation diagrams and a read of all OTA PCI ID's from a tower and adjacent
with dominance statistics. I can get my hands on another 1 or 2 instruments for
around 4K.  I'm not sure how much adding the TDD options will be, but I know it
will be well worth it.

We also purchased a Sunsight AAT for Azimuth and tilt.  We are working on a
deadly accurate RNP moving forward.  Already on 2 of the towers, the azimuths
were out by a 10-15 deg magnitude and tilt was not 100%.

We are hoping with these tweaks we will be able to take our LTE network to the
next level of quality.

Cheers,

Subject: [Telrad] Compact 3000 4X4 Patch

Anyone have a status on the following?

"Note 4x4 on the Compact 3000 is not supported in this build but coming within a few
weeks.  So only the Compact 1000 for now,  Thanks Nick"  - This was 7/29/2016.

I finally stayed up through the night to get everything updated to the 6.6 only
to find out by reading the fine print afterwards that 4X4 was not supported
yet.  Long frustrating night. And no help for the clients who are suffering

We are running the 3000 on 15 mhz band 41.  Has anyone found upload to be an
issue?  It seems like I don't have any clients running more that a few hundred
k upload.  Occasionaly I find one that will pull 2 megs.  I'd be interested to
know what others are doing and if there is something we can do differently.  If
I recall when we set this up we set it at 75/25 for the split.  I'm looking up
info now on playing with that setting a little.  But honestly with only 15 mhz
to play with we don't have a lot of download to give up.  Anyone else running
this way, or have thoughts or comments on the setup?

Thanks - Paul
