4. Roles and responsibilities
• Network Performance Engineer
- Supervise hardware upgrade activities
- Frequency channel testing and evaluation of results
- Coordination with CRU to upgrade all CPEs before
frequency upgrade
- Identification and rectification of issues faced during
channel testing activity.
- Final frequency upgrade
- Extend support during customer migration
- Optimization activities

5. Roles and responsibilities
• Access network
- Arrange site access
- Site configuration
- Audit of sites (Soft and hard parameters)
- Identification and rectification of issues
- Extend support during optimization

6. Roles and responsibilities
• NOC
- Soft parameter configuration as recommended by
network performance team
- Soft parameter audit
- Frequency channel testing
- Frequency upgrade
- Identification and rectification of issues
- Extend support during optimization

7. Technical limitations
• Augmented network noise
– Increase in co-channel interference due to
change in frequency plan (4 frequency to 3
frequency plan)
– Solution: Physical optimization (Azimuth &
Tilting) and IRC enabling (disable CSM)
• Coverage shrinkage
– Compromised coverage area at cell
boundary.
– Solution: Physical optimization (Azimuth,
height, Tilt) and EIRP modification, TE, DL

8. Challenges
• Wateen/Augere
– Create delays in project execution
• Reasons of creating delays
– Customer churn
8

9. Solution to Challenges
• Cluster wise migration starting from
lowest impact clusters
• NAP priority
• Optimization
• Cluster wise Wateen site closure starting
from lowest impact clusters.
