With the continuous advancement of intelligent mining,the deployment scale and application scenarios of mine networks are expanding,which pose higher requirements for wireless communication in terms of rate,latency,and reliability.Wi-Fi 7,corresponding to the latest IEEE 802.11be protocol standard,is the next-generation wireless communication technology that provides a new wireless communication solution for mine network construction.In terms of application deployment,the technical characteristics and effects of Wi-Fi 7 are analyzed from the perspectives of rate enhancement,low-latency guarantee,and interference suppression.By adopting strategies such as wider bandwidth,higher-order modulation,and multi-user MIMO,Wi-Fi 7 achieves a significant rate enhancement,aiming to reach a target of 30 Gbps.Through the introduction of mechanisms such as Multi-AP joint transmission and multi-link operation,Wi-Fi 7 can provide reliable low-latency guarantee,aiming for a target of less than 5 ms.By utilizing techniques like preamble puncturing,C-OFDMA,and spatial reuse,Wi-Fi 7 establishes strong interference suppression capabilities to meet the demands of complex environments.For intelligent mining construction,a network architecture represented by Mine PON+Wi-Fi 7 is proposed,along with applications such as digital twin working surfaces and remote equipment control.The integration of Wi-Fi 7 with 50G PON,coexistence with 5G/5G-Advanced,and collaboration with various Wi-Fi protocols are also analyzed in terms of future development prospects.It can be foreseen that after large-scale commercial use,Wi-Fi 7 will become a low-cost,high-value information infrastructure for intelligent mining.
