Mining

Mines can be dangerous and frightening places.  They are dark, wet, and thousands of feet underground.  There is often just an elevator or two to service hundreds of personnel on multiple levels, hundreds of feet apart or more.  Communications are typically accomplished using portable radios which leverage a cabled system known as "leaky feeder."  Or a wireless mesh system, which relies on line-of-sight, may be deployed.  These systems are vulnerable to accidents which can leave miners without communications and they are difficult to connect in some areas underground. 

Vital Alert offers an effective, cost-effective back-up and network extension to both of these technologies.  Because it is wireless, there are no expensive cables to install or maintain.  Unlike wireless mesh systems, it does not rely on line-of-sight, reducing the costs of installing numerous wireless access points and repeaters.  It works with and extends the reach of existing communications and warning systems.  It can be deployed at the drill face and in other areas where leaky feeder systems do not exist.
