Most underground mines – in Africa and around the world – have a two-way radio network to handle important voice communications. Many also have a WiFi network or other proprietary network to provide access to data from monitoring instrumentation (geotechnical, hydrological, gas detection/air quality etc.), vehicle/equipment and personnel tracking systems, etc.
Mostly, these two systems operate independently, leading to a significant amount of infrastructural duplication. This can increase installation and maintenance costs, and cause delays.
i want to add LTE(wifii over leaky feeder) to an existing (or new) VHF/UHF leaky feeder network, creating a single mine-wide hyper-efficient communications network that can handle all of the mine’s voice communication and data transfer needs.
New, high-bandwidth, low-power communications networks can be set up automatically LTE-ready, or LTE functionality can be easily added to existing already installed networks by replacing existing 2-way BDAs (bi-directional amplifiers/comms boxes).
Migration of existing networks to LTE is very simple. The BDAs can be installed by any qualified electrician, and the system makes use of the existing leaky feeder/radiating cable network, preserving the functionality of VHF/UHF equipment and systems that are already in use.
