Consistency Is an Engineering Feature LTE · VoLTE · Network Governance · 6 min read Networks rarely fail because of a single bad decision. They fail because small inconsistencies accumulate over time — each one harmless in isolation, disruptive in combination. Working across large LTE and early VoLTE environments made this impossible to ignore. Two neighboring clusters could run the same software, support the same features, and still behave differently once real traffic and mobility came into play. The difference was rarely dramatic. A legacy handover threshold left over from an earlier tuning cycle. A power setting adjusted for a specific interference condition that then propagated as a template. A parameter inherited from rollout that no one had reviewed since go-live. These were not mistakes. They were drift — and drift compounds. How drift accumulates Configuration drift is not a single event. It builds across change cycles. Each individual modification ha...
