What can be reason for UL interfrence other then a Jammer?


#1

what can be reason for Ul interfrence other then Jammer


#2

1- Other operators may use same frequency
2- possible if you have PCI conflict and collision
3- lots of UE camped on the same cell
4- faulty repeaters or third party repeater nearby the site


#3

kindly tell me what the difference is between pci collision and pci conflict.
thanks


#4

PCI conflict means : you are serving from cell and the neighbor cell have the same PCI of your serving one . …PCI confusion means : you are serving from cell and have 2 neighbors have the same PCI for example you are serving from cell X and 2 neighbors (Y &Z ) have the same PCI


#5

Also you have to check PCI mod6 interference


#6

If we have check pci mod 3, is it necessary to check pci mod 6? And why?


#7

Thanks for share meaning, may i ask again : is there any other ways for improve snir? Is it volume also impact to bad snir?

Or may be there are parameter for improve snir? Kindly asking advice


#8

I think yes, because mod6 related to MIMO 2*2


#9

Mod6 related to SISO which mean 1T1R, for MIMO22 & MIMO44 we check Mod3
