LTE-M1 Cellular Products

With the family of RANGER products & cloud interface, SignalFire offers a platform to easily and quickly deploy measurements where you need them with the least amount of hardware. The key objective of this product line is to monitor and even control without traditional systems like SCADA, PLC, edge device, etc. We created a solution that brings the sensor data right into an easy-to-use and mobile friendly cloud interface. The RANGER can be connected to your existing sensors with analog or digital outputs for monitoring parameters such as pressures, levels, flow meters, and temperatures.

SignalFire’s cellular solution integrates the latest in wireless technology, allowing direct connectivity from a sensor to a cloud platform. Using LTE-M (short for LTE CAT-M1) this technology is for Internet of Things devices to connect directly to a 4G network, without a gateway, using the built-in batteries or external solar panel. Find out if there is LTE-M coverage in your area.

The electronics and embedded firmware have been designed for ultra-low power consumption to maximize battery life.

The RANGER comes complete with the web and mobile-friendly SignalFire Cloud interface to monitor, trend, and get alarms either by text or email. It uses MQTT technology secured by TLS (latest in internet security) that can also be integrated with private cloud platforms. The data is published natively using the popular SparkPlugB format commonly utilized by many hosting platforms.
