Optimization & DT
-
BTS Optimization:-
Sectors azimuth and tilt to be done as per RF planning.If needed, azimuth and tilt to be changed as per DT report.
Drive Test:-
Ensure DT software loaded in to the laptop.Laptop to be connected to the GPS & USB dongle or CPEs as per coverage then open the Drive test tool.Required parameters to be selected in DT tool.Select the record mode in DT tool and start test and record the session for DT.Move in and around 15km from the BTS sectors wise and record the same.If needed, re-optimization to be done in BTS based on DT report.
