The NetPort-able IS Node is a dual radio 802.11, four antennae, completely wireless (no fiber) open platform Wi-Fi access point encased in a small and rugged Pelican case, weighing 13.2 pounds (6kg).

 

The node was originally designed for Mine Rescue operations to allow rescue workers to immediately set up temporary communications networks underground for their search and rescue operations.

 

Mine Rescue staff carry the NetPort-able IS access points underground, setting them down at distances of up to 3000 feet (1km) apart along mine tunnels, and then use VoIP handsets or the NLT IS-approved two-way text Messenger cap lamp to communicate with each other and back to surface.

 

In addition to Mine Rescue, the NetPort-able IS Node can be used in day-to-day operations by mines for temporary network extensions, either stand-alone or with an existing 802.11 fiber-based network, during longwall moves or set-ups, or to temporarily replace access points that may be down for maintenance.

 

Any 802.11 open standard client device, such as VoIP phones, PDAs, laptops and Wi-Fi tags, can run on the network.

 

It is powered by two Northern Light NiMH batteries with 8 hours of run time, which are changeable in return airways.

 

“I am thrilled with this approval as it gives our customers even more flexibility in the design of MSHA-compliant communications and tracking solutions,” NLT president Heidi Levitt said.

 

“Because no fiber is required, the NetPort-able IS node becomes a practical solution for communications in the face areas, where MSHA requires much smaller tracking zones.”

 

NLT’s family of MSHA-approved products includes two styles of fixed access points, NetPort IS, for main travel ways; NetPort IS 3FR with three fiber ports, allowing for an additional fiber and access point run off a main loop; NLT Messenger IS, a two-way text messaging device in a cap lamp; Wi-Fi tracking tags with Aeroscout; and the NLT Digital Mine software that pulls together tracking, communications and environmental monitoring into a single Internet-based front-end on a laptop or server.
