S/N CELLNETWORK
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.
