What does a 4G network engineer do, what's the significance and what's his job?

The so-called 4G network engineer is a senior electrician+network knowledge.

Mainly responsible for the construction of 4G network equipment, often pulling wires outside, building equipment, and going to the launch tower in Dashan to repair hardware. Fortunately, it is maintained at the base station, so you don't have to walk around much. You have to go to the door to help customers maintain, build a network and eliminate various network failures.

At present, China has just started to build 4G, which may be ok in recent years, but after the completion of 4G construction, there will definitely be a serious surplus of network optimization engineers, and it will be even more difficult to survive then.
