基于IEEE802.11b协议的矿井无线局域网系统研究

s we all know, the cable network system under the mine is difficult to lay out and maintain, and it can not be moved at will; on the country, WLAN technology developed rapidly in recent years. The system is wireless and is not restricted in the layout of nodes, network users can get access to the network at any time. What‘s more, the installation of the WLAN system is tremendously simply, it can be used flexibly and extended easily. Based on the reasons above mentioned, the establishment of WLAN network system under the mine based on the IEEE802.11b protocol is proposed in this paper. The network has a lot of advantages such as good compatibility with standardization, and high bandwidth, multilevel wireless relay. The paper mainly introduces the mine wireless LAN system composition, operation mode and its underground video transmission, scheduling, speech and personnel safety monitoring application of mine environment.
