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.

Coverage GAP
Drop call due to coverage issue. Azimuth change of ZAN016B From 280
to 260 to cover the GAP and improve coverage. New site is needed to
improve coverage.

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.

Recommendations Summary:
Antenna optimization of ZAN047C from 6ET to 2ET to improve coverage
performed DT to check signal strength before and after the physical
changes.
ZAN006F is serving on opposite direction with better signal
strength of
-83 dBm. Recommend to double check suspected swap feeder connection
of sectors ZAN006F & ZAN006E.
Sector Optimization of ZAN047B; azimuth change from 220-240 needed
to improve coverage.
Drop Call due to poor Rx Quality of ZAN047A with BCCH 6 having
adjacent Channel with ZAN005A with BCCH 7.For freq retuning
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.
Drop call due to coverage issue. Azimuth change of ZAN016B From 280
to 260 to cover the GAP and improve coverage. Long term solution,
new site is needed to improve coverage.
