About This Architecture

Multi-site private 5G network architecture connecting 14 remote sites via gNB (NR) base stations to a centralized core through microwave backhaul aggregation. UE/CPE devices at each site establish wireless connectivity through dedicated gNB-01 through gNB-14 nodes, with all traffic converging at an STC aggregation tower supporting 240 Mbps microwave links and 1.54 Gbps total backhaul capacity. The centralized Private 5G Core implements 3GPP functions including AMF, SMF, UPF, PCF, AUSF/UDM, and NRF/NSSf for subscriber management, session control, and policy enforcement. Security is enforced via firewall/ACL and WAF before traffic reaches Internet/Cloud Services, which include CDN, load balancers, app servers, databases, and object storage with integrated monitoring and OAM. This architecture demonstrates how enterprises can deploy carrier-grade 5G networks across geographically dispersed locations while maintaining centralized control and cloud integration.

How do you design a private 5G network architecture for multiple remote sites with centralized core functions?

This diagram shows a 14-site private 5G deployment where each remote site has a gNB (NR) base station serving UE/CPE devices, with all sites connected via 240 Mbps microwave links to an STC aggregation tower. Traffic flows through a centralized Private 5G Core implementing 3GPP functions (AMF, SMF, UPF, PCF, AUSF/UDM, NRF/NSSf) with security enforcement via firewall/ACL and WAF before reaching Int
