With the expansion of the Internet of Things, companies find themselves facing the challenge of integrating multiple devices and protocols, many of which have different power and connection requirements. This mixing may also include traditional techniques.
IoT gateways are becoming an important part of building a powerful IoT and providing computing capabilities in edge computing scenarios. Edge computing distributes the load on the system by performing data processing on the data source or "edge" instead of relying on a central server to complete most of the work. This is the source of IoT gateways (such as OAS platforms).
An IoT gateway is a solution for implementing IoT communication (usually device-to-device communication or device-to-cloud communication). A gateway is usually a hardware device equipped with application software that performs basic tasks. At the most basic level, the gateway facilitates the connection between different data sources and targets.
An easy way to imagine an IoT gateway is to compare it to a home or office network router or gateway. Such a gateway facilitates communication between devices, maintains security, and provides a management interface where you can perform basic functions. IoT gateways can do this and more.
What function does the IoT gateway perform?
From simple data filtering to visualization and complex analysis, IoT gateways have evolved to perform many tasks. These smart devices are helping to drive the current wave of IoT expansion.
