PLANNING & OPTIMIZATION RELATIONSHIP
PLANNING NETWORK EVALUATION PATH
1. Basic coverage deployment
2. The first capacity extensions and coverage enhancement deployment (indoor coverage)
3. Intelligent capacity enhancement deployment with strong indoor coverage improvement
4. Base station coverage area splitting/microcellular/dual band deployment, to further improve coverage/capacity/quality

DATA COLLECTION Data of network plan
Network basic information collection 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.
Let’s begin!
RF OPTIMIZATION

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

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
