In the Internet, a gateway is an intermediate device that connects an intranet to other networks on the Internet, also called a “router.” In the architecture of the Internet of Things, a gateway is needed between two different networks, the perception layer and the network layer. The intermediate device is the “IoT gateway”.
IoT gateways have been a fundamental element of Industrial IoT architecture for many years and are arguably the most important architectural component, serving as a bridge between different networks and allowing IoT-generated data to be transmitted to the cloud.
But as use cases and applications for IoT have evolved across different industries, especially in the past three or four years, architectural requirements have also changed. As more and more businesses look to take advantage of the IoT, the definition of what constitutes an Pasarela IoT and the role a device plays in the broader IoT architecture is becoming blurred.
An IoT gateway at its most basic level is “a device that connects things on the LAN, whether it’s IoT sensors or other devices, to things on the WAN, and the polymer that just traffics and delivers it.”
While there are still some gateway devices that play this role in some architectures, a variety of factors include the need for higher computing power at the edge, growing security concerns, evolving IoT customer needs, and the convergence of the IT and OT worlds. The overall acceptance has triggered an evolution beyond those gateway-centric IoT architectures.
Of course, the technical capabilities of the gateway have not yet reached the end. As the market demand becomes higher and higher and the Internet of Things technology continues to improve, I believe that more comprehensive Pasarelas IoT will continue to be updated and emerge, providing more opportunities for the future development of the Internet of Things. good service.
The development of the Internet of Things architecture has also driven the development of many enterprises, and the two complement each other. Zongheng Intelligent Control has been deeply involved in the field of Internet of Things for several years, constantly researching and innovating, and using advanced Internet of Things technology to develop the 4G wireless gateway ZHL4921 to meet various industrial field applications, integrated design, equipment access, data collection, relay control, and rich interfaces , stable and easy to use.
