What types of enterprises are engaged in the communication industry? Such as operators, equipment, terminals, etc. What are the famous enterprises in each category?

This industry is actually very concentrated. If the classification can be divided into operators and equipment vendors, operators are mobile, telecom and China Unicom, equipment vendors are Huawei, ZTE, Datang and Fiberhome, and foreign equipment vendors are Cisco, Ericsson, Nokia Siemens and Alang.

In fact, the terminal is not a communication industry in the traditional sense, but it is actually closer to consumer electronic products.

At present, the communication industry and IT industry have been very integrated, that is, ICT integration, and the boundaries between communication and IT industries will gradually blur. Just like the current mobile phone has many other functions besides making phone calls, such as surfing the Internet, socializing, stock trading, games and so on. Many software service providers are providing services to end users, while operators are not only providing traditional communication services.
