This Verizon-certified LTE Cat-M1 router, the ICR-3211B, is a WWAN solution for applications that don’t require high speeds usually associated with 4G LTE. LTE Cat-M1 devices provide similar speeds to 2G (375kbps up/down), better building penetration for urban or bunkered installations and lower power for battery-powered applications. It has a built-in supercapacitor for sending “last gasp” messages if the primary power supply is interrupted. Other features include an open Linux platform with development support for Python, Node-RED, C/C++, Ethernet and RS-232/485 interfaces for flexible connected device support, dual SIM cards and internal eSIM, a rugged metal enclosure and an operating temperature range of -40 to 75 °C.
