Intelligent gateway classification: According to different functions, it can be divided into four categories:

a) Category I: only has the function of adapting to network interface;

b) Category II: In addition to the function of a type of gateway, it also has the function of data aggregation and processing;

c) Class III: In addition to the function of Class II gateway, it also has the function of supplying power to lamp pole equipment;

d) Four categories: In addition to the three types of gateway functions, it also has AI extension functions.
