Yes, we have not had success with 105, UE continually disconnect and do not 
come back for long periods of time. We have also experienced many customer 
complaints about speed issues.

Rolling back to .89 solves the speed issues, and greatly improves the 
disconnects. Telrad blames interference, which may be some of the cause, but 
not all of it.

Thanks Terry
I am running F1F2.  So leave the eNB at 6.6 and move the UE's to .89 ?

Why back to .89?  Are there problems with .105?

Ian, if you are running version 105 on the UE's, try downgrading to .89. Also, 
with the sectors not back to back using F1F2 would be better.

There are only 12 UE on that eNB. Average plan is 1x5. CINRS are all pretty 
good.  I can lock them to the sector freq based on geographical location but 
thats a pain if I need to change channels.

Now I see in BV that UpLink utilization is higher than it has ever been
at 91% (peak was ~75% previously)  vs. DL at 58%.   I expect UL to drop
or at least stay the same since we mitigated the noise slightly.

I stopped frequency locking the UE's - could the UL utilization be
caused by UE's that are on the 'wrong' sector ?

How many UEs are on your ENB that's seeing high up utilization?

We're currently wrangling with high upload (96% and more) usage on at least one 
sector in the low 20s. CINR are fairly high across the board. Seems to be new 
since 6.6, and doesn't seem to make much difference whether we're in 2x4 or 4x4 

We've been comparing the output of "show ue-info active-ue-info-list 
to identify UEs on the wrong sector. However, we're not using split mode, so I 
doubt that would be helpful for you - from what I recall, split mode just 
splits the RF chains, not the overall LTE capacity, so a client has no way to 
identify which sector it's on.
