This paper presents a structured radio network optimization methodology applied to a local operator in Algeria for different generatiuons 2G, 3G, and 4G networks, integrating drive test measurements, ATOLL and Python radio coverage simulations, and electrical antenna tilt adjustments via Ericsson ENM/AMOS. Since the deployment of 5G in Algeria has been launced only in early 2026, field measurements related to the electrical tilt effect cannot be conducted at the time of this study. The methodology effectively mitigates overshooting cells while maintaining coverage continuity in the mentioned generations. Post-optimization evaluations, using drive test measurements and collected KPIs from Business Objects (SAP), demonstrate significant improvements in signal strength, quality of service, handover performance, and user throughput, alongside reduced interference. Outdoor 4G throughput increased by approximately 60%, while indoor throughput gains ranged from doubling to nine-fold across different zones. These enhancements are supported by improvements in RXLev, RSCP, RSRP, Rxqual, Ec/Io, and SINR, ensuring stronger cell dominance and a more stable user experience. The obtained results are validated through both simulation and field measurements. The proposed methodology provides a scalable framework for national deployment of mobile networks.
