9. DATA COLLECTION
 Data of network plan
 Network basic information collection
Let’s begin!  The base of network plan and optimization
 The engineering survey data of new sites
 Confirm the network plan information.
 The Engineering data of the current network
 Understand the current network .
 The configuration NMS data.
 Understand the current network configuration.
Collection of various performance reports of the
currently deployed network.
 Subscribers’ complain
 The supplement information showing the
network quality.

10. RF OPTIMIZATION

Cost Resources

11. OPTIMIZATION OBJECTIVES
 Finding and correcting any existing problems after site
implementation and integration.
 Meeting the network quality criteria agreed in the contract.
 Optimization will be continuous and iterative process of
improving overall network quality.
 Optimization can not reduce the performance of the rest
of the network.
 Area of interest is divided in smaller areas called clusters
to make optimization and follow up processes easier to
handle.

12. PROPOSED METHODOLOGY
 Problem Analysis
 Conduct Drive testing
 Gather statistics
 Subject to investigage (Faulty TRX, Coverage
overlaps, drop calls, capacity & interference
issues)
 Simulate real-time scenario on TEMS (after
DT)
 Export into MAPInfo to check cell overshoot
coverage, etc
 Propose solution

13. EXPECTED OUTCOMES
 Good signal coverage at macro and micro
sites
 Rx Quality level should be good
 No interference issue

26. CONCLUSION
• Satisfactory coverage and quality were found
• In most of the location, additional walk test
has been carried out where Operator hasn’t
deployed micro layer
• Macro sites should provide coverage to
mobile users located in open environment
