What is an IoT gateway?
The Internet of Things gateway (Gateway) is also called an Internet connector and a protocol converter.
The IoT gateway implements network interconnection above the network layer. It is the most complex network interconnection device and is only used for network interconnection between two high-level protocols with different protocols.
The IoT gateway can be used for both WAN interconnection and LAN interconnection. A gateway is a computer system or device that does the heavy lifting. Used between two systems with different communication protocols, data formats or languages, or even completely different architectures, the IoT gateway is a translator.
Different from the IoT gateway which simply transmits information, the gateway must repackage the received information to adapt to the needs of the destination system. Same layer - application layer.
