The Internet of Things (IOT) interconnects devices, objects, and systems in a simple and transparent way in order to share information and coordinate operations between the disparate systems and devices. Sensors collect various types of data such as temperature, humidity, ambient light, and inventory levels and share it with the cloud using wireless or wired communication protocols. An IoT gateway acts as a communication bridge between the IoT sensors and devices and a backend cloud server.

An IoT gateway device performs critical tasks such as to facilitate inter-compatibility across the IoT network. The IoT gateway also performs several operational tasks such as to manage device configuration, perform device authentication for secure network access and support edge-analytics. IoT gateways help bridge the gap between operations and IT infrastructure within a business. They do this by optimizing system performance through the operational data they gather and process in real-time in the field or at the network edge.
IoT gateways provide several benefits to an IoT network such as high scalability, low hardware costs, fast production with a less time-to-market, reduces telecommunications cost, mitigate risks, and increases security. Gateways reduce burden on individual sensors by handling complex processing and memory and storage requirement. It can reduce machine-to-machine (M2M) traffic, isolate malfunctioning devices, and provide encryption to the communications between the sensors and the cloud through public key infrastructure (PKI).
Challenge affecting IoT gateway hardware and software market growth is in enabling interoperability of end nodes while supporting multiple connectivity sensor protocols such as Z-Wave, ZigBee, BLE, and Wi-Fi. Other constraints include maintaining backend connectivity, performing caching and queuing of data, power overloads or power outages, and adequate serviceability options. A gateway needs to consider the criticality of the application, mitigate the effects of a loss of connectivity to the backend, and provide minimum functionality within the IoT sensor network in case of power outages.
The global IoT gateway hardware and software market can be segmented based on enterprise size, component, deployment, application, and region. In terms of enterprise size, the IoT gateway hardware and software market can be bifurcated into small and medium enterprises (SMEs) and large businesses. Based on component, the IoT gateway hardware and software market can be classified into hardware, software, and services. The hardware segment can be sub-segmented into processors/microcontrollers, IoT sensors, protection circuitry, and connectivity modules (such as Zigbee, Bluetooth, and WiFi).
In terms of deployment, the IoT gateway hardware and software market can be categorized into on-premise, cloud, and hybrid deployments. The services segment can be further categorized into managed and professional. Professional services can be segregated into prevention, maintenance, and production optimization. In terms of application, the IoT gateway hardware and software market can be classified into smart home automation, smart factory automation, vehicle automation, remote monitoring, and fleet management.
