Cellular Gateways (2G/3G/4G/LTE/NB-IoT/5G) are communication devices that connect IoT nodes and sensors to central servers or cloud platforms via cellular networks. They serve as a bridge between field devices and the internet, enabling real-time data transmission over long distances, particularly in locations where wired or local wireless networks are impractical.

These gateways support a variety of cellular technologies, including legacy 2G/3G, high-speed 4G LTE, energy-efficient NB-IoT, and 5G for bandwidth-intensive IoT applications. By leveraging cellular connectivity, they provide reliable, secure, and always-on communication, ensuring continuous monitoring and control.

Cellular gateways are widely used in smart cities, remote industrial sites, fleet management, utilities, logistics, and large-scale IoT deployments, enabling scalable and efficient system integration.

Modern cellular gateways are robust, compact, and scalable, often incorporating edge processing, data aggregation, and protocol conversion to optimize network efficiency. By bridging distributed IoT nodes with cloud platforms, they empower organizations to collect, analyze, and act on real-time data, supporting automation, operational efficiency, and data-driven decision-making across diverse environments.
