2G OBSERVATION AND RECOMMENDATION
OBSERVATION:
1. Poor indoor coverage observed at certain areas of the walk test.
2. Poor indoor quality areas was due to poor coverage also overshooting cell causing missing
neighbour definition between LG3288B and 453A.
3. LG3288B and LG2205B overshooting.
RECOMMENDATION:
1. Perform audit on 453A to get the antenna orientation, antenna height and antenna tilt.
Also improve 2G indoor coverage at customer place by performing physical optimizationbased on the audit result.
2. One degree electrical down tilt on LG3288B and LG2205B.
