Rather than relying on public mobile networks or stretched Wi-Fi, large sites such as factories, ports and mines increasingly run their own private 5G network. It covers just that location, giving reliable, high-capacity wireless that the operator controls and tunes to its needs.
A dedicated network supports many sensors, cameras and moving machines with steady performance and keeps sensitive data on site. Setting one up takes investment and expertise, and it must be managed like any critical system, so it suits operations where dependable, local wireless directly affects productivity and safety rather than ordinary office use.
