    Bad Rxlevsub and Rxqual sub during the drive test and around 300m of the site can be an indicator for bad VSWR

    Depends in your network ...

    Take it as network level and check , most drop happend with which category level or quality uplink or down link also which layer 900 \1800 , after this the dececion will be easy , then u can take delta of the drop comparing between 2 dates to know where the increamnt happend ,,, after this check which cella have more drop mean contributed the drop
    You need to check after u understad the issue , TA , interfernce , path balance and alarms then if not of theses you need to go more details based on the case

    Blocking can be due no resource or RF issue
    but for congested issue will be only resource issue

    3.Feeder Cable swap
    4.Parameter wrong definition
