What professional category does the communication engineering major belong to?

Communication engineering aims to accomplish the first thing mentioned in the communication principle: to provide reliable and effective (good and fast) information transmission. Of course, it would be better if we can achieve low cost, high mobility and low energy consumption.

2. If it is employment, there are three main outlets for civil communication: operators provide services for consumers; Equipment manufacturers manufacture and develop transmission equipment; It is not enough to have equipment and customers. The middleman design institute builds a communication platform for consumers to connect.

Equipment manufacturers have the greatest relationship with communication technology, while others have more communication with people. In addition to the above-mentioned civil cellular networks, there are also some applications and research of special frequency bands and technologies, such as millimeter-wave and low-frequency devices, optical transmission and quantum communication, which are mainly completed by research institutes and pre-research departments of some companies.

For the development of communication engineering, many people will tell you to switch to CS as soon as possible, because the communication industry has entered the sunset industry. (Because of the rise of the mobile Internet, the computer major has revived, and many EE people have gone to CS. I want to say more. )

The thing is this: communication technology is pipelined, and the communication industry is like laying a water supply pipeline for a city. It only cares about quality, cost and how to lay pipelines, but not much about content. CS that provides content is different. People can provide tap water, mineral water, soft drinks and functional drinks. . . . For consumers, who cares what the pipeline is, so all the money goes to Internet products. When the communication business develops to a certain extent, the money people are willing to spend on it will not increase significantly, even if you provide better technology.

Ps: The pipeline of wired communication is paved, and the Internet is on fire; The wireless communication pipeline is paved, and the mobile Internet is on fire!

Communication equipment manufacturers and even the communication industry are originally tall industries, and the entry threshold of the industry is relatively high. It is impossible to use the products of several equipment manufacturers. If you want to drink water, you have to look into their eyes. If you don't give money, you will be cut off. Huawei's participation has greatly reduced the profits of the whole industry, reduced the right to speak, and made the whole industry embarrassed. Of course, this is black Huawei, and the wheel of historical progress has been doomed! Look at the apples like chestnuts. Equipment is not important, service is important.
