1. Background & Challenges
With the continuous development of infrastructure, the safety and daily operation management requirements of underground tunnels and utility corridors are becoming increasingly strict. Supervisory authorities demand higher standards for real-time monitoring, efficient maintenance, and rapid emergency response.
However, underground environments present unique challenges:
- Complex and narrow structures
- Harsh conditions with multiple bends and obstacles
- Poor penetration for traditional wireless signals
- Limited time for emergency communication deployment
These factors make it difficult to ensure smooth communication for daily operations and emergency rescue.
