Background

WiFi 6 technology is a new generation of wireless local area network (LAN) transmission technology. On September 16, 2019, the Wi-Fi Alliance announced the launch of the Wi-Fi 6 certification program. WiFi 6 is primarily used for indoor wireless internet access, offering advantages such as high transmission speeds, a simple system, and low cost. However, it is not suitable for high-speed mobile communications. This technology primarily utilizes technologies such as OFDMA and MU-MIMO. MU-MIMO (Multi-User Multiple Input Multiple Output) allows a router to communicate with multiple devices simultaneously, rather than sequentially. MU-MIMO allows a router to communicate with four devices at once, while Wi-Fi 6 will allow communication with up to eight devices. Wi-Fi 6 also utilizes technologies such as OFDMA (Orthogonal Frequency Division Multiple Access) and transmit wave shaping to improve efficiency and network capacity.

Overview

The mine wireless communication system (WiFi 6) consists of both surface and underground systems. The surface system includes the core network and the dispatching host. The surface system includes an industrial Ethernet ring network switch and an intrinsically safe power supply for mines. The underground system includes an industrial Ethernet ring network switch, an underground communication substation, a positioning card reader, an intrinsically safe Wi-Fi mobile phone, a mine-grade wireless camera, an intrinsically safe power supply, and other equipment.

This comprehensive system meets the needs of underground production scheduling, personnel attendance, high-definition video surveillance, data communication, and voice communication. It also offers excellent stability, security, and a long service life.

The system is primarily used for voice and video communication scheduling, high-speed wireless data transmission, auxiliary transportation monitoring, remote equipment control, and personnel and equipment location monitoring.
