ISSUES/EVENTSREASON COMMENT/RECOMMENDA

1 118B

Poor quality and

fair coverage

There is the fair or reduced coverage and

poor quality along this road close to

T118_MTN Switch due to the blockage of

the signal of 118B by a building

Change the azimuth of 118B from

120o and also increase the anten

from 30m to 35m for better covequality.

2 FC0101D

Handover failures,

Poor Coverage

and Quality

Handover failures occurred from FC0101D

to 1709A which is not a configured

neighbour. There is crossed feeder on

FC0101 causing reduced or poor quality

and coverage around T1709 (indoor site

at Valencia Hotel) which is also having alow signal strength at the area

The swapped sectors or feeder cr

FC0101 should be corrected. Conf

1709A as neighbour to FC0101D,

FC0101E,FC0101C,FC0101F bi

directionally.

3 5848DA

Handover failure,

Poor Quality and

Reduced/fair

Coverage

Handover failures occurred from 5848DA

to 116C which is an overshooting cell that

is not configured as neighbour. There is

also reduced or fair coverage and poor

quality at this area due to the overshooting

cell 116C

Do mechanical down tilt of 116C

degrees to improve HOSR, qua

coverage.

4 1502DBHandover failure

and Poor Quality

Handover failure occurred from 1502DB

to FC0101E and FC0101C which are

missing neighbours, resulting poor quality

and coverage.

Configure FC101C,

FC0101F,FC0101B,FC0101E

neighbours to 1502DB and 150

improve HOSR, coverage and q

5 1026DBDropped Call and

Blocked Call

Dropped call occurred here on 1026DB

due to its reduced coverage strength at

this area. Also, failure of 1026DB to

handover to 1443A or 1443B, caused

blocked to occur as the coverage and

quality reduced drastically

Configure 1443A and 1443B as ne

to 1026DB and 1026DB. Also con

change the azimuth of 1026B from

140o . Down tilt 1026B electrical

degrees to improve coverage and

the area

6 5848DB

Handover failure,

Poor Quality and

Fair Coverage

Handover failure occurred from 5848DB

to 1495C due to missing neighbours.

1495C has a very low signal at the area

causing reduced coverage and poor

quality.

Configure 1495C and 1495D

neighbours to 5848B and 584

Configure 1495DC as neighbour t

Configure 1495C and 1495D

neighbour to 5848DA. Down tilt

mechanically by two degrees to

quality and coverage

Conclusion

7

The network performance at Wuse II is averagely good and okay but the net

quality needs to be optimized as there are areas at the city with reduced o

quality due to interference and overshooting cells resulting into handover fa

and blocked calls.
