Suspected feeder swap

Late SHO

Detected Missing neighbour

Pilot Pollution

Suspected transmission issue

Detected Missing neighbour

Detected Missing neighbour

Poor quality due detected Missing neighbour

Suspected hardware failure/transimission issue

Suspected hardware failure/transimission issue

Detected Missing neighbour

Detected Missing neighbour

Detected Missing neighbour

Pilot Pollution from DL0003V(at distance of 3.21km)

Poor coverage and quality due detected Missing neighbour

COMMENT/ACTION

Add 4073GC and 4025GC as neighbour to each other

Electrical downtilt of +2 on DL0003V to reduce its Pilot Power

Check 4091GB for any alarm/antenna fault.

Down tilt 4194GD

Resolve the suspected feeder swap on 4109

Review SHO between 4029GB and 4029GA

Add AN0117X and AN0025X as neighbour to each other

Electrical down tilt of +2 on AN0130V

Check 4034GD for any transmission issue as no call was establised on it.

Check and add 4016GB,4074GB and 400GC as neighbour to each other.

Add 2829GA and 4836GA as neighbour to each other.

Add 160GE and 2829GF as neighbour to each other.

Add AN0561Y and 4879GE as neighbour to each other.

Check 4833GD for any transmission related issue.

Check 4833GD for any transmission related issue.

Add AN0047W and 219GC as neighbour to each other

Add 4007GE and AN0552Z as neighbour to each other.

Add 4061GE and AN0552Y as neighbour to each other.

REASON

Poor coverage

Poor coverage due to availabity issue on 4837

Poor coverage/quality

Poor coverage/quality due to unstable availability on 4024B

Poor coverage due to missing neighbour

Congestion on TCH

Poor quality caused by co-channel interference.

Poor quality .

TCH congestion AN0047A

Poor coverage on the serving cell AN0036B

Poor coverage/quality due to outage of 4061

Poor coverage/quality distance cell 4045B due to availability issue of 4091B

Poor coverage/quality due to late handover to a better neighbour cell 4045B even when the coverage get bad

Poor coverage and bad quality due to unstable availability on 4833

COMMENT/ACTION

Check and resolve suspected alarms/feeder fault on 4091B.

Review handover parameter between AN0056A and AN0023B

Resolve and normalise the availability of 4837A

Review/adjust handover parameter between 4073B and 4045B

Mechanical Up tilt is recommended on 4041DA to improve coverage.

Check the coverage of 4024 and stabilize it.

Add 4103DB and 4103C as neighbour to each other

Frequency retune on 4039B(BCCH-91) and AN0054A(BCCH-91)

Electrical down tilt of +1 on AN0025B to allow dominance of closer cell.

Resolve and normalise the availability of 4833

Normalised now need to be monitor,also nomalise the availability of 4833

Check AN0036B for faulty hardware/Antenna

Brings 4061 back on air.
