What is the best way to go for interference analysis
Effects:
a. Could HO be affected due to interference apart from Call drops and call setup failures?
b. Suppose my region is covered by ARFCN X and there are no interfering X-1 and X+1, but there could be some other ARFCNs (say Y, Y+1) with lower signal strength that also covers the given area and they cause interference. Should this be taken into account for interference analysis?
c. What should be minimum difference between the signal levels of the victim and the interferer in case of a. co-channel b. adjacent-channel.
Ie: effects when victim is at -70 dBm and interferer at -94 dBm or when its -70 and -74.
d. what is the strategy when there is a chain of interferers: victim's ARFCN is X and is interfered by X+1 which in turn is interfered by X+2
Currently, I see servCI along with RxQual and for the regions where RxQual is bad, I check servCI with sector handles of cells that have corresponding coverage.
Regards!!
