摘要: 宽带无线通信是智慧矿山建设的基础和关键。提出了矿井宽带无线通信特殊要求：需无线全覆盖煤矿井下长达10余千米的巷道；无线发射必须本质安全防爆；无线工作频段不宜过高；无线传输宜具有一定的绕射能力；抗干扰能力强；移动性要求不高等。研究了矿用5G和WiFi6，指出5G和WiFi6均可用于智慧矿山宽带无线通信；矿用5G具有传输速率高、传输时延小、通话质量高等优点，但系统复杂、成本高；矿用WiFi6具有传输速率高、系统简单、成本低等优点，但传输时延大、通话质量低。Abstract: Broadband wireless communication is foundation and key of smart mine construction. Special requirements for mine broadband wireless communication were proposed. Wireless signal is required to cover roadway more than 10 kilometers coal mine underground. Wireless transmission must be intrinsically safe. Wireless working frequency band should not be too high. Wireless transmission should have certain diffraction ability. Anti-interference ability is strong. Mobility requirements are not high. Mine-used 5G and WiFi6 were researched. Both 5G and WiFi6 can be used for broadband wireless communication in smart mine. Mine-used 5G has advantages of high transmission rate, small transmission delay and high call quality, but the system is complex and cost is high.Mine-used WiFi6 has advantages of high transmission rate, simple system and low cost, but transmission delay is large and call quality is poor.
