5 MHz-10 MHz Network up-gradation

1

Network upgrade

• Scope• Roles and responsibilities• Technical limitations• Challenges• Suggestions

2

Scope• Hardware upgrade• Frequency channel testing• Cluster wise frequency upgrade• Soft parameter tuning• Qubee customer migration to 10MHz• Wateen customer migration to

Huawei RAN• Optimization

3

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

4

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

5

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

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 map repetition, QPSK repetition enabling

7

Challenges

• Wateen/Augere – Create delays in project execution

• Reasons of creating delays– Customer churn

8

Solution to Challenges

• Cluster wise migration starting from lowest impact clusters

• NAP priority • Optimization• Cluster wise Wateen site closure

starting from lowest impact clusters.
