firstly in 2G there is no pilot pollution, we can relate the term as UL and Dl interference,
if we are having good Rx level but Rx quality is poor then below are the resons behind it.
# Same BCCH or TCH pr BSIC will be there.
# Some cells are overshooting at that place.
# UL and DL interference may be worst which will be found in Reports 196,210 in Nokia.
#Check SQI and BER .
# TCH interference was there which will be found in live BSS .
#UL and DL interference may be due to some hardware issue or any external source
any issue mail me on
