Coverage Issue
Coverage issue: Antenna optimization of ZAN047C from 6ET to 2ET to improve coverage performed DT to check signal strength before and after the physical changes.
Poor coverage; Antenna optimization
Poor coverage; Azimuth optimization

Suspected Swap feeder
ZAN006F is serving on opposite direction with better signal strength of -83 dBm as shown.
Recommend to double check feeder connection of sectors ZAN006F & ZAN006E.

Poor Rx Quality
Poor Rx Quality due to no dominant serving cell in the area. Recommend to Build a New site. Sector Optimization of ZAN047B; azimuth change from 220-240 needed to improve coverage.

Drop Call 2 & 3
Drop call due to overshooting of ZAN014B having -105dBm with bad quality 7. Recommend to down tilt ZAN014B from 3ET to 6ET; BCCH 6 of ZAN014B also having co-channel interference with BCCH 6 BSIC 20 as shown above.

Drop Call 5
Drop call due to call dragging of ZAN027D having -98dBm with bad quality 6. Check neighbor definition of ZAN027D to ZAN044C and ZAN043F. Check freq of ZAN043F if created in BA list ZAN027D.
