					WiFi / RFID Tracking
 Both systems are managed through the 
					Northern Light Digital™ Tracking software which displays the 
					location of assets underground. Asset location is identified 
					using tracking tags. Tags transmit RF signals to readers 
					which link to the software via the Northern Light Digital™ 
					Network. Tags can be stand-alone or integrated into the cap 
					lamp to eliminate tag battery replacement and reduce lost 
					tags.

					NL Technologies Northern Light Digital™ Network and 
					Nodes The Northern Light Digital™ Network is 
					today’s solution for communications underground. The 
					Northern Light Digital™ Network is a modular, robust, 
					network infrastructure designed for underground mining. The Northern Light Digital™ Network 
					supports VoIP and data communications underground. Based on 
					the Ethernet network standard/technology, the Northern Light 
					Digital™ Network is a true Open Standards Network. This 
					means that distinct, multiple purpose-built networks can be 
					converged onto a single network. The Northern Light Digital™ 
					Network can also integrate with legacy systems to protect 
					prior technology investments. For more information visit
