Awareness, misconceptions and management of wireless coexistence in mining - ME Feature Article

Wireless technologies are becoming vitally important for modern mining operations. Used for increasingly complex tasks — such as miner and asset tracking, proximity detection, teleremote and autonomous equipment operation, and environmental monitoring — the ability of wireless systems to perform their intended functions satisfactorily in the presence of other wireless systems (coexist) is critical not only to the successful operation of modern mines but also to the safety and health of mine workers. Concerns regarding the ability of wireless systems to coexist can often hinder the decisionmaking process for adopting technologically advanced wireless systems. However, with adequate knowledge of the concepts of coexistence and appropriate wireless system management, coexistence concerns do not need to be an impediment to the successful adoption of wireless systems. There are several common wireless coexistence-related fears that can inhibit adoption of wireless technology: fears that safety-related systems may not operate properly when needed, failures could disrupt production, and wireless systems may inherently require costly troubleshooting. Most of these fears can be alleviated through proactive activities.
