Abstract: The deployment of Private 5G networks for mission-critical industrial applications demands a fundamental shift from best-effort cellular planning to a deterministic, reliability-focused design. This paper presents a rigorous engineering framework for constructing Standalone Non-Public Networks (SNPN) capable of supporting Industry 4.0 use cases, such as isochronous motion control and high-density machine vision. We analyze the key trade-offs between spectral efficiency and latency and propose a dimensioning method that emphasizes uplink-heavy Time Division Duplex (TDD) frame structures (e.g., DSUUU) to achieve gigabit-class uplink capacity. Additionally, we detail the physical-layer planning required for high reliability in cluttered Indoor Factory (InF-DH) environments. The integration of Time-Sensitive Networking (TSN) is discussed through the IEEE 802.1AS transparency model and accurate Quality of Service (QoS) mapping strategies. Finally, we recommend a Zero-Trust security architecture utilizing Subscription Concealed Identifiers (SUCI) and secondary authentication to enhance the industrial edge.
