Detailed Answer
4G/5G is mainly used for remote monitoring and remote maintenance of industrial remote controls: 4G modules upload equipment status and alarm information to the cloud platform in real time; 5G's high bandwidth and low latency can support remote video monitoring and predictive maintenance. However, the real-time control link (millisecond-level, jitter-free) is still handled by the dedicated 433/470MHz link — 4G/5G depends on base station coverage and has blind spots and latency fluctuation. High-end monitoring solutions from LIDER and XINGJIA use a dual-channel approach: 'dedicated band for control + 4G/5G for monitoring'.
| 4G/5G | Monitoring / maintenance |
| Control | Dedicated band |
| Solution | Dual channel |
Note:For remote control, use a private network solution; public 4G/5G should only be used for monitoring.
