Specifically, NIOSH has reviewed existing sensors and communications network systems used in U.S. underground coal mines to determine whether they are capable of supporting IIoT systems. The results show that about 40 percent of the installed post-accident communication systems as of 2014 require minimal or no modification to support IIoT applications. Boliden has installed such a Wi-Fi communication system to enable the use of drill rigs in Aitik. Although it has delivered a new level of productivity, the experience has not been flawless. Wi-Fi is not designed for the wide area outdoor coverage required by an open-pit mine like Aitik, and this solution also severely limits the addition of other automated machines.

For the first time in the history of Ukraine, energy group DTEK has laid a Wi-Fi connection at a depth of 500 m in the Jubilee coal mine (Dnipropetrovsk region). Almost 130 km of cable were used and 400 access points were installed. Based on this wireless

At the Falkirk mine, the network enables data transmissions to and from the mining equipment. Coal trucks are linked to an innovative GPS system which uses 802.11 to relay logistics information to the central office network, which tracks vehicle locations, active and planned mining areas, and time sensitive operations data.

Finally, a cable-free, lightweight, portable Wi-Fi repeater was available that could easily and quickly take the network to every active corner of a mine. The WRN, used in conjunction with a mine's existing fixed Wi-Fi network, is designed to bridge the signal between a cabled network access point and the dynamic mining areas where cabling is not practical or economical to implement.

The network covered about 85 percent of the mine's 13.5-mile tunnel system at the time the case study was written. The wireless access points within the mine connect to Cisco Industrial Ethernet 2000, 3000, and 4000 Series Switches, intended to function in harsh environments.
