I have Alpha 4x4 65 degree sectors.  This eNB is Split Sector 
SplitModef1f2;.  I'm running Subframe 2/0.


What is the impact of having the Sectors not at least 90 degrees off 
from each other ?  I ask because we increased tilt to 10 degrees today 
and it had a minimal impact on the problem and over half the of the UE's 
were unable to connect because the foot print was so small.


At +6 and -50 degrees bearing I saw a 6dB improvement in the noise 
floor, and all UE's connected but that means the Alpha's are only 
separated by ~60 degrees.  They are 10' apart horizontally. If I turn 
the other Sector further out to avoid that then it will be hitting the 
next tower 35 Km away so I'd prefer not to do that.

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 ?

Or am I beating myself with a stick due to the Sectors being so "close" 
now?


Cheers,
