BACKGROUND
Underground communication systems used by mining companies are usually based on using a backbone based on leaky feeder cable technology. This provides voice access using walkie-talkie channels and data access using cable modem based technology. In essence, there is no proven broadband wireless technology available that has both high data rates and high coverage.
Through a deep understanding of the requirements of the mining industry, UQAT’s LRTCS laboratory undertook a multi-year development project to bring modern communication technology to the harsh underground environment. The result is a patent-pending breakthrough technology based on using next generation leaky feeder technology to its full potential.
The resulting technology allows underground WiFi connectivity throughout the mine as well as 3G cellular access and other advanced communication protocols.
TECHNOLOGY
The invention was prototyped in the CANMET underground teaching mine and will be verified in a full scale commercial mine soon.
