NLT NetPort-able IS Mode Receives Approval by MSHA (Mine Safety and Heath Authority) in the U.S. for Safe Use in Coal Mines

摘要

NL Technologies (NLT) announces the approval by MSHA for the newest addition to their IS approved family of Wi-Fi access points and network client devices supporting communications and tracking solutions for US coal mines, NetPort-able IS Node. The NetPort-able IS Node is a dual radio 802.11, four antennae, completely wireless (no fiber) open platform Wi-Fi access point incased in a small and rugged Pelican case, weighing only 13.2 lbs (6 KG). The NetPort-able IS 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 (1 km) apart along mine tunnels and then use VoIP handsets or the NLT IS approved 2 way text Messenger~(TM) cap lamp to communicate with each other and back to surface.
