IoT gateways solve a major challenge in IoT systems: connecting devices that speak different “languages.” These gateways translate various protocols (like MQTT, Modbus, or Zigbee) into a format compatible with cloud servers. Without IoT gateways, many IoT setups would fail to operate efficiently. They also provide local intelligence through edge computing, allowing for faster decisions and reduced network load. For businesses building smart systems—whether in agriculture, water management, or industrial automation—IoT gateways are the essential technology that bridges the gap between devices and the digital world.
