Smart LTE Cat 4 Gateway

The next-generation LTE SGL81 IoT Gateway combines field-proven technology with Embedded Processing for a wide range of applications demanding cost-effective LTE Cat-4 speeds. A 20-pin GPIO connector and multiple interfacing options enable applications that require sensor interfacing, actuator control, data processing or protocol translation at the edge.


Product Description

An easy-to-use migration option for gateway applications using PLS62T and ELS61T, the future-proof LTE Smart Gateway provides out-of-the-box global LTE Cat-4 connectivity with seamless 3G/2G fallback for a flexible, cost-effective platform to connect industrial assets using field-proven LTE technology.

The 20-pin GPIO connector (GPIOs, SPI, I2C, PWM) and higher bandwidth enables a wider range of applications including video surveillance, robotics, Industry 4.0, remote maintenance & control, smart cities, vending machines, and healthcare applications

Form Factor Family

The next-generation Gateway SGL81 reduces time to market with simplified integration, manufacturing and logistics for a wide range of applications. The SGL81 is available in three variants including USB/RS-232, RS485 and LAN options.
