The system has the ability to transport streaming data such as voice and video over multiple wireless feeds. In recent years, coal mine safety has come under intense scrutiny in the wake of numerous fatal incidents.

Wireless Sensor Network (WSN) used under the coalmine tunnel is an emerging area of research that promises to provide reliable and flexible communication. This paper first discussed the best working frequency about the WSN in coalmine. Then, according to the actual circumstances of coal mine, the network structure should adopt cluster-tree topology.Mining HNT is done by installing a simple device on your office window. That's it. Seriously. Hotspots provide miles of wireless network coverage for millions of devices around you using Helium LongFi, and you are rewarded in HNT for doing this. And because of an innovative proof-of-work model (we call it "Proof-of-Coverage"), your ...

A strong communications system underground could help reduce mining accidents and increase the effectiveness of rescue operations. A wireless radio network would be a key component of an effective communications system. Using radio waves, miners could remain in contact with surface operations. Sensors hooked up to a wireless radio network …WiFi and wearable tracking devices for underground coal miners in India. Priya Ranjan Kumar, founder of Bengaluru-based EasyM2M Technologies, is quoted in The Economic Times, India saying that in the country's coal mines, "one miner dies every third day. A lot of time is lost in miners trying to communicate to the surface during an accident ...

Wifi is a necessity in the modern world. If you don't have Wifi wherever you are, you're in for a bad time. At the same time, Wifi networks can themselves be the cause of pretty amusing things. Free unprotected Wifi is like a diamond in a coal mine.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 ...
