As the backbone of interconnected IoT systems, an IoT gateway plays a pivotal role in facilitating seamless communication and data exchange between edge devices and the cloud infrastructure. This multifunctional device serves as a conduit for transmitting sensor data, commands, and control signals, effectively bridging the gap between the distributed network of IoT endpoints and the centralized processing and storage resources. By leveraging its connectivity features, including support for diverse communication protocols such as Wi-Fi, Bluetooth, Zigbee, and LoRa, the IoT gateway ensures interoperability and compatibility across heterogeneous IoT environments. Furthermore, IoT gateway often incorporates edge computing capabilities, enabling localized data processing, analytics, and decision-making at the network edge, thereby reducing latency and bandwidth usage while enhancing overall system efficiency. With robust security measures and management functionalities, IoT gateway serves as a cornerstone in building secure, scalable, and resilient IoT ecosystems across various domains, including smart cities, industrial automation, healthcare, and agriculture.
