Post-Disaster, Underground Communication

Post-Disaster, Underground Communication

There is a wide array of equipment currently employed in tunnels and mines, to allow underground personnel to talk to each other and to the surface. This includes:

Wired Equipment

• Telephones
• Public Address
• Loudspeaker

Fibre-optic Equipment

• Ethernet VoIP
• Multiplexed Baseband Audio

RF Equipment

• Distributed Antenna
• Leaky Feeder
• Node (Mesh)

These technologies all have their benefits and find use in different applications. However, they all have one major weakness, their method of communicating with the surface.
