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.

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.

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.
