5G Best-Practices: Private 5G vs. Wi-Fi 7, high-speed communication with sovereignty, security, and service level agreement

In critical infrastructures, industry, and public safety, predictable performance, resilience, and data sovereignty are key. We show when private 5G with licensed radio planning, end-to-end quality of service (QoS), and mobility makes the difference, and when Wi-Fi 7 with multi-link operation, high density, and cost efficiency is unbeatable. The focus is on decision-making rules rather than hype: radio design, latency/jitter targets, security/data protection (zero trust, EU sovereignty), and brownfield migration paths. With architecture blueprints and clear TCO/OPEX classification.
