Cost Reduction through network consolidation

Operator Challenge

The operator aimed for a network consolidation as part of M&A. The target was to reduce Capex/Opex through RAN sharing. It was unclear how to maximise cost savings while preparing for future proof 5G rollout & shared wholesale network

Omnitele Assignment

  • Design MOCN or MORAN network with RAN sharing
  • Maximise cost savings through site distmantling
  • Reduce costs of high band 5G introduction through optimised shared network
  • Determine required network expansions to ensure long term QoE with the foreseen traffic growth

Solution

Omnitele applied predictive analytics based network consolidation design.

Input for the analysis

  • Defined targets for coverage & Quality
  • Forecasted 5y traffic growth
  • Input network plans & OSS data

Analysis steps

  • Coverage integration:
    • Integrate networks
    • Remove excessive sites
    • Mitigate coverage gaps by antenna swaps
  • Capacity & Spectrum integration
    • Distribute combined future traffic to sites
    • Predict future quality in remaining sites
    • Quantify RAN expansions to sustain quality targets
  • HLD, LLD, & Implementation
    • Implement shared network design, verify SLA

Output of the consolidation design

  • 37% of the sites dismantled
  • Coverage & data throughput exceeded the targets
