Check whether high traffic or interferece cause the high RTWP.7LMT uplink frequecny scannigdo the scanning in NodeB LMT (need block the sector)8Check the intermodulationMML command: SET TXSWswitch off the downlink tansmit power and monitor whether interference disapper or notSite visit and information collection10Visit the siteWhether 3G system shared antenna with 2G or not? Whether TMA used or not? Whether repeater is located nearby?11whether primary and secondary RTWP are both have highswap the primary feeder with the secondary feeder to check whether high RTWP swap or not.12differentiate internal or external interferenceDisconnect the jumper from the cabinet and then monitor the RTWP.
