Sounds good. To note...in 2.3...our furthest tower is 110KM from an AT&T site...and we are affected heavily during ducting periods. It is real...and it sucks...hopefully we will have a good news story once we are done with AT&T.

I think we are currently at 3 degrees with this one. The truck just pulled out to go play with this a little. I was excited by the upgrade over the weekend. I also upgraded a handful of clients hoping to see great improvements but I actually got a text this morning saying it was worse! The client went from having around 1 meg upload to .04 when he finally got the test to load. I don't see how we can have any interference on this 2.5 license. We are the only licenses around here for miles and this is our only deployment so far. We will see how this helps. Thanks again for the feedback. Paul R.

The LTE gear carries far, and I think many of us are causing self interference. If your HAAT (height above average terrain) is much lower that your site (say you have a tower on a hill or mountian) then you need to take this into account as well. The more tilt you can use, the less interference your going to hear... The better you are going to perform. We anticipate having to tilt upto 10deg at some sites.

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.

"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 poor uploads. 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 Paul R.
