Sierra Wireless | HSPA+ Intelligent Gateway
AirLink LS300 HSPA+ Intelligent Gateway

The AirLink LS300 gateway has a small footprint for easy installation and a rugged, military spec design (MIL-STD 810) that enables it to withstand extreme temperature changes, humidity, shock, and vibration. Certified for hazardous environments (Class I, Div 2), the LS300 is ideal for industrial deployments. Designed to be the next generation, all-in-one product, the LS300 comes standard with Ethernet, serial, digital I/O, and USB interfaces, as well as GPS enabling you to:

  • remotely monitor and control your infrastructure and surveillance equipment on pipelines, meters, pumps, and valves in any energy, utility or industrial application;
  • instantly connect your equipment at remote point-of-sale locations, temporary installations, or retail operations;
  • track the location of heavy equipment and assets in the field, while providing reliable internet connectivity to your mobile workforce.

The ALEOS Application Framework and integrated development environment make it easy to process data inside the LS300. Collect and analyse information from connected equipment and optimize data transfers using a simple, Lua-based scripting language. Now you can program an AirLink gateway without deep embedded expertise.
