Am now switched to android, but had an app in my Nokia, that was almost like the field test. Through which i can log, not only basic but advanced parameters including Handover, cell reselection, power and gprs parameters. Also call attempts, successful attempts, call terminations, failures and much much more…
the data from various devices once uploaded to the server may guide the operator about what the user is experiencing. As per my experience, RF KPIs show great values, while the customers still churn about problems that due to system limitations are not reflected well in performance statistic.
