The Application of WiFi 6 Technology in Underground Mine

Aiming at the problems of large power consumption of 5G communication technology equipment and short wireless transmission distance of wireless signal, the author designs the wireless network coverage scheme of WiFi 6 in coal mine to achieve the fully coverage of 5G communication. This paper makes an exposition of WiFi 6 technology from the aspects of technical principle, networking mode, antenna design and power consumption calculation. The WiFi 6 signal coverage scheme solves the problem of wireless network signal coverage in long-distance roadway underground coal mine by realizing the full coverage of wireless network. The data of laboratory experiments and coal mine roadway simulation show that with the characteristics of wide network communication coverage area, fast communication speed and low power consumption, WiFi 6 network scheme can fully meet the requirements of full wireless coverage in coal mine.
