COVERAGE & QUALITY PLOT (2G / 3G)

2G


COVERAGE PLOT(3G)


QUALITY PLOT(2G)

Poor quality due to Adjacent Channel Interference on the serving cell LG3127B(BCCH-83) and cell U0903C(BCCH-84).Down tilting of 903C can help to reduce its inference level in the area.


QUALITY PLOT(3G)

Poor quality as a result of poor coverage. Improving the coverage by bringing up planned sites (LG2210 & LG2800). See slide 17 for more details.

OBSERVATION AND RECOMMENDATION.

OBSERVATION 1.The dominant 3G cell in the area is LG2891W. 2. POOR Coverage AND QUALITY WAS EXPERIENCED in MOST PARTS OF THE estate. 3. POOR DATA Throughput OBSERVED WITHIN ONIRU ESTATE. RECOMMENDATION. 1. PLANNED SITES LG2210 & LG2800 ARE RECOMMENDED TO BE BROUGHT ON AIR ON 3G TO

IMPROVE COVERAGE WITHIN ONIRU ENVIRONS WHICH WOULD SUBSEQUENTLY IMPROVE DATA THROUGHPUT. Refer to slide 4 for site locations.
