RF Planning & Optimization

  1. 1. CONTENTS Introduction Background Literature Review Optimization Objectives Proposed Methodology Expected Outcomes Discussion on Results Conclusion Reference
  2. 2. SYNOPSIS In this presentation, you will learn how the GSM network planning is done. Drive testing to gather radio statistics Analyze the network performance Proposed solutions to resolve issue or meet KPI benchmark
  3. 3. MOTIVATION Challenging area of research Comprehensive knowledge on the subject Day-to-day learning
  4. 4. LITERATURE REVIEW
  5. 5. PLANNING & OPTIMIZATION RELATIONSHIP Planning Optimization Implementation Site survey Capacity Evaluate Coverage Frequency interference Optimization Parameter design
  6. 6. PLANNING NETWORK EVALUATION PATH1. Basic coverage deployment2. The first capacity extensions and coverage enhancement deployment (indoor coverage)3. Intelligent capacity enhancement deployment with strong indoor coverage improvement4. Base station coverage area splitting/microcellular/dual band deployment, to further improve coverage/capacity/quality
  7. 7. PLANNING STEPS Frequency Coverage LAC Interference Propagation Capacity Channel Neighbor cell Site survey Coverage Parameter E-map
  8. 8. 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.
  9. 9. RF OPTIMIZATION Quality Optimizatio nCost Resources
  10. 10. 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.
  11. 11. 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
  12. 12. EXPECTED OUTCOMES Good signal coverage at macro and micro sites Rx Quality level should be good No interference issue
  13. 13. DISCUSSION ON RESULTS
  14. 14. INTERNATIONAL ARRIVAL LOUNGE RXLEVEL IDLE
  15. 15. INTERNATIONAL ARRIVAL LOUNGE CELL ID IDLE MODE
  16. 16. INTERNATIONAL ARRIVAL LOUNGE RX-QUALITY
  17. 17. AVARI RXLEVEL IDLE
  18. 18. AVARI CELL ID IDLE MODE
  19. 19. AVARI RX-QUALITY
  20. 20. MOBILE MARKET SADDAR (9574) RXLEVEL IDLE
  21. 21. MOBILE MARKET SADDAR (9574) CELL ID IDLE MODE
  22. 22. MOBILE MARKET SADDAR (9574) RX QUALITY
  23. 23. MAPINFO SNAPSHOTS
  24. 24. MAPINFO SNAPSHOTS
  25. 25. 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
