Update on Pre drive recommendation summary
 Coverage/Quality Gap Solutions recommended for 3G/4G poor coverage Gaps
• 3 new sites proposed for 3G/4G.-Open
• 3 sites proposed for Carrier Addition(1800 2nd) (from optimisation scope)- 2 done 1 in WIP
 Physical optimisation recommended:
• 18 LTE cells & 18 UMTS cells proposed for physical optimisation under drive and optimisation scope out of which
11 LTE & 7 UMTS cells physical optimisation completed.
 Sector swap:
• 1 swap site given as per suspecting from HO stats (Site ID: 75566) , which is not conformed in drive - due to no
roads driven in all 3 sectors.-Closed
 Temp/Backhaul congestion:
• 8 LTE sites found temporary Congestion – due to York Races Ebor Festival_2018 which is resolved later. -Closed
 Site off air, Under development & Faulty tickets:
• 1 Site (LTE_19637) found site off air during drive and later restored-Closed

Results Summary
3G
•
Coverage is found degraded by 2.61% due to optimisation implemented (65827C1).
•
Quality also found to be degraded by 2.59% due to the optimisation activity (96150A1).
•
There is also 2 drops found in Voice analysis for which carrier upgradation (10761 to 10786) has been proposed for 2 sites.
•
Throughput has been degraded by 0.86% due to the optimisation activities ,congested sites.
4G
• Coverage found to be degraded by 2.93% due to the optimisation activity (59020A11, 65828A11).
• The throughput is degraded by 4.44% also due to Coverage & quality degradation
Other analysis
•
75555,19589,59003 having availability issue from long time (dead cells).
•
4 cells having are found with RF congestion (59009C1,96174C1,96714B1,9967A1) which is already in pre.
Drive observation– Evidence pack summary
Out of the 4 Cells which is identified in the evidence pack one site is having KPI degradation and rest under WIP.

In post drive,
1. Good RSRP >=-80 dBm has been degraded by 2.93%
2. Over all SNR has been slightly degraded by 0.2% for threshold level of > 5 dB.
3. Good range of CQI (>=10 and <15) has been slightly degraded by 1.98%
Coverage and quality are degraded to small extent and the same is due to the implementation of tilt after the pre drive.
