What is a 4G smart gateway and what functions does the smart gateway implement

 The industrial-grade IoT gateway is a data transmission device that fully supports 5G/4G/3G/2G communication networks. The 4G smart gateway realizes two-way, transparent, and wireless transmission between serial devices and servers, and between serial devices and serial devices. , the Internet of Things gateway has the characteristics of simple use, USB/Bluetooth setting parameters, remote maintenance, etc. It can easily develop user monitoring software or connect to third-party application platforms through cloud platform forwarding, protocol development kits, and network-to-serial port tools.

The role of smart gateways

The smart gateway is an indispensable part of the smart home. It is the controller that realizes the operation of the entire smart home system. Its functions include not only the collection, input, and output of information, but also remote and linkage control. Therefore, for smart home manufacturers, producing and developing a good smart gateway is the key to winning users in the market; for consumers, the quality of the smart gateway also determines the quality of the smart home products they buy. overall experience. 

Functions realized by the intelligent gateway

1) Ability to perceive network access. First of all, the intelligent gateway has the function of obtaining information such as the attributes and status of each node, that is, it can perceive the real-time status of each node. Secondly, it has functions such as remote control, wake-up, and diagnosis of nodes. 

2) Intercommunication capability of heterogeneous networks. The access of intelligent gateways inevitably requires cross-domain communication, so perfect addressing technology is required to ensure that the information of all nodes can be accurately located and queried.

3) Communication and data format standardization. The intelligent 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 the command Parse, and then convert into signals and control instructions that can be recognized by the perception layer protocol.

To put it simply, the intelligent gateway mainly completes three tasks, the first is to collect the data of sensor nodes; the second is to perform data protocol conversion; the last is to quickly send the data after protocol conversion to the public network. In addition, it should also have corresponding management and control capabilities.
