From Two Networks to One: What Large-Scale RAN Integration Really Breaks First LTE · 5G NSA · RAN Integration · 8 min read Large network integrations don't fail where people expect them to. Capacity is rarely the first problem. Coverage isn't either. What breaks first is assumption alignment. The biggest technical challenge was not spectrum reuse or site consolidation. It was reconciling how two nationwide RANs interpreted the same user behavior differently. On paper, both networks were healthy. KPIs looked reasonable in isolation. Once traffic began shifting at scale, the mismatches surfaced quickly. Where the mismatches appeared None of these were red alarms. They showed up as soft degradation — retries, increased setup times, edge failures. The kind of problems customers feel before dashboards turn red. First failure classes to surface at scale Mobility at inter-network boundaries: Handover decisions tuned within each RAN independently Inter-netw...
