2. HOW TO FIND MOD3,6,30
COLLISION
The algorithm can find the MOD(3),MOD(6) and MOD(30) collision for
each cell which has cross coverage area with another cell, and this
algorithm will implement traversing in every single cell one by one for
whole network.

9. ADVANCED FEATURE (1)
1. Single Cell PCI Tuning
Base on the output report, you will get the mod(3),mod(6) and
mod(30) collision cells list, and then system will provide you a
candidate value list support you to find the prober PCI.
The following table is an example which system will show you after
big data analysis.PCI MOD(3) MOD(6) MOD(30) Cross Area Cell Distance

179 2 5 29 8 1.3KM
234 0 0 24 12 0.9KM
156 0 0 6 14 0.8KM

10. ADVANCED FEATURE (2)
. Whole network PCI smart distribution
Once the RSRP confirmed, the system can fill the following table, and then
implement the algorithm to distribute PCI with different mod(3),mod(6) and
mod(30) values for the cells which get cross area from maximum to
minimum.
Finally, we will make the network with minimum cross coverage area with
mod(3),mod(6) and mod(30) collision. And also base on the big data
analysis, we will put solution as well, to adjust some particular cell’s antenna
down tilt to make the mod collision as small as possible.
