A private 5G network puts the radio units and, usually, the core network inside a factory, port, mine or campus so that traffic never leaves the site. Spectrum can be leased from an operator, allocated locally where regulators permit, or taken from shared bands such as CBRS in the United States. The result is cellular reliability, mobility and security without depending on public network load.
It competes with Wi-Fi rather than replacing it: 5G handles mobile robots, AGVs and cranes that roam across large areas and need predictable latency, while Wi-Fi remains cheaper for fixed laptops and tablets. Costs are higher, both in equipment and in skills, and the device ecosystem for industrial 5G modules is still maturing. Operators also offer hybrid models using network slicing on their public networks as a lower-commitment alternative for industrial IoT.
