Smart city networks require multi-layered infrastructure combining fiber, wireless, and IoT technologies. A robust fiber optic backbone connects critical facilities (traffic management, public safety, utilities) with diverse ring topologies ensuring redundancy. Wireless mesh networks extend connectivity to street-level sensors and devices using technologies like LoRaWAN and NB-IoT. Small cell deployments on light poles provide 5G coverage for mobile users and devices. Converged networks carry both operational technology (OT) and information technology (IT) traffic with appropriate QoS policies. Cybersecurity assumes critical importance with segmented networks isolating sensitive systems like traffic controls and surveillance. Edge computing nodes process data locally to reduce latency for time-sensitive applications. Unified network management platforms provide visibility across all infrastructure layers. Future-proofing requires ample spare conduit capacity and scalable interconnection points.
