1 Basic Information
1.1 Drive Test Route
1.2 Details of Network Optimization Activities •
• •
•
Physical Verification of Sites for any discrepancies in implementation versus planning data. Please Site Audit Template Parameter consistency checks and gets the change request implemented. Parameter dump can be provided as on when required. Detailed drive tests with Long call and short call to verify the call performance in terms of receive level, call quality, call set up, handovers, call drops. Done. Coverage optimization by means of physical changes at site. Refer Site Audit Template

• •
Signal level checked at various major hotspots. Please refer the drive plots. Sector swap details if any. Refer Site Audit Template
Audit data cluster 8.xlsx
1.3 New sites recomandation Show it in Mapinfo and give planed site list as exel.
