Earlier I shared Private 5G and their Real-world Use Cases in South Korea from Netmanias here. One of the deployment case study was that from Korea Hydro & Nuclear Power (KHNP) that has deployed a private 5G network and applications at the Hanul Nuclear Power Plant in December 2022, enabling rapid response to disaster situations.
As per Netmanias post, there were three main reasons for this deployment:
- Security: There have been 1,463 hacking attempts to KHNP in the last 10 years, and a closed network completely separate from the commercial communication network is needed (such as the leak of internal data at KHNP in 2014).
- Disaster response: Even when nuclear power plants are isolated from public networks due to natural disasters such as forest fires, typhoons, and earthquakes, a stable private network that operates normally without being affected by them is needed(in 2022, a large wildfire in Uljin caused the loss of some sections of the public mobile communication network near the Hanul nuclear power plant).
- Full Control: If KHNP uses the MNO's private 5G service, the MNO's public 5G network is managed by the MNO, so KHNP cannot change the 5G network configuration.
