Industry-4.0

Private 5G (also non-public 5G, dedicated 5G, or campus/industrial 5G) denotes 3GPP-conformant 5G systems operated for a defined organisation or site — factory, port, mine, hospital, stadium, or utility — rather than as a nationwide public mobile service. 3GPP Release 16+ formalised Non-Public Networks (NPN) with two principal models: Standalone NPN (SNPN) — an isolated PLMN (dedicated MCC/MNC or PLMN ID) with its own 5GC and NG-RAN; and Public Network Integrated NPN (PNI-NPN) — a slice or dedicated DNN on a public operator’s 5G with contractual isolation. Private 5G delivers URLLC-capable connectivity, local breakout (traffic stays on-site via local UPF), deterministic QoS, and control over upgrades and security policies — advantages over Wi-Fi 6/7 in mobility, scheduling, and industrial TSN integration scenarios, at higher cost and regulatory complexity.

Edge computing in telecommunications places compute, storage, and application execution close to users and devices — at cell sites, regional points of presence, or on-prem enterprise locations — rather than only in distant hyperscale data centres. The goal is to reduce end-to-end latency, limit backhaul load, satisfy data residency, and enable real-time applications (AR/VR, industrial control, V2X, video analytics) that are impractical with 50–100 ms round trips to central clouds. In 5G, edge is tightly coupled to the user plane: a local UPF on N6 breakout forwards traffic to an edge data network (DN) hosting MEC applications without hairpinning through the operator’s core hub.
