What is a 5G smart gateway

　　 5G smart gateway can integrate the information collected by different things and transmit it to the next level, so that information can be transmitted between each part. 5G smart gateways can realize protocol conversion between perception networks and communication networks, as well as different types of perception networks, and can realize wide-area interconnection as well as local-area interconnection.

　　5G smart gateway mainly implements the following three functions:

　　 The ability to perceive network access.

　　The gateway of the Internet of Things first has the function of acquiring information such as the attributes and status of each node, that is, it can perceive the real-time status of each node. The second is to have the functions of remote control, wake-up, and diagnosis of the node, that is, to realize the automatic management of the node.

　　 The ability of 5G smart gateway to interoperate with heterogeneous networks.

　　 Internet of Things gateway access must have requirements for cross-domain communication, so perfect addressing technology is needed to ensure that the information of all nodes can be accurately, efficiently, and safely located and inquired. With the development of Internet of Things applications, the number of node addresses will gradually increase, and their coding structure is different from the domain name structure in DNS. Therefore, a set of addressing technologies different from the Internet is required to meet the demand.

　　 Communication and data format standardization.

The gateway must realize the protocol conversion from the sensor network to the traditional communication network, uniformly encapsulate the standard format data transmitted on the protocol adaptation layer, unpack the data sent by the wide area access layer into standard format data, and realize command analysis , And then converted into signals and control commands that can be recognized by the perception layer protocol.
