The invention provides a 5G network communication device. The 5G network communication device comprises a lower ring body, and a dense and ultra-dense networking technology block; wherein the lower ring body and an upper ring body are both semi-cylindrical structures, and the left ends of the lower ring body and the upper ring body are rotationally connected by a rotation shaft; a longitudinal body sense detection block is arranged on the inner wall of the lower ring body and the upper ring body with an even interval; a tilt display screen is fixedly arranged on the front half part of the topof the upper ring body; and a charging socket is arranged on the rear end of the left side wall of the display screen. The 5G network communication device is set with an all-duplex transmitter, and the transmitter and receiver of the 5G network communication device occupy the same frequency resources and work at the same time; therefore, the uplink and downlink of the both ends of communication can use the same frequency at the same time, and the frequency division duplex and time division duplex modes in the prior art are broken, which is one of the keys for communication nodes to achieve two-way communication, and is also the key technology for high throughput and low latency required by 5G.
