The basic measurements of scanner are CPICH_RSCP (received signal code power)CPICH_Ec/No (received energy per chip divided by the power density in the band)RSSI (received signal strength indicator)What can you achieve with scanner?Crossed feeder issues (DL) Coverage verificationInterference problems (overshooting cell, pilot pollution)Missing neighbours PILOT TUNING
