CalAmp unveiled a 4G LTE cellular router and gateway for AT&T networks that runs embedded Linux on a 400MHz ARM9 processor. The LMU-5000LTE is equipped with LTE, HSPA, and EVDO routers, a 50-channel GPS, and multiple I/O, and features fleet tracking, as well as user-programmable PEG (Programmable Event Generator) monitoring software.
The LMU-5000LTE combines gateway, routing, and M2M monitoring functions to enable organizations to set up managed cellular networks using AT&T’s 4G LTE mobile broadband network. It is designed to support remote monitoring and control, industrial and energy remote asset management, enterprise fleet management, workforce automation, and point-of-sale applications, says CalAmp.

The device’s Linux-based firmware includes CalAmp’s PEG alert engine, which monitors external conditions and responds to customer-defined, exception-based rules based on thresholds like time, date, motion, location, geo-zone, and input. Also provided is the company’s PULS (Programming, Update and Logistics System) for over-the-air device (OTA) management and maintenance. PULS enables OTA updating of Linux applications, configuration parameters, PEG scripts, and firmware.
All this runs on a modest 400MHz ARM9 processor with 64MB RAM and 128MB flash memory. Ethernet, Serial, and dual USB ports are also provided, along with several Molex ports. These support an additional power-switching serial port, as well as GPIO, dual 1-wire interfaces, and other I/O.
The device offers a cellular router and gateway supporting LTE, HSPA, and EVDO, each with fallback modes. The 50-channel GPS “tracking engine” offers 2-meter accuracy and -162dBm tracking sensitivity, and there are even accelerometers designed for driver behavior, motion, and impact sensing.
