Abstract

Wireless multimedia mesh network is used for longwall coal mine face to transmit signal of data, voice and video in real time with the development of modern coal mine. The performance of the backhaul network especially it´s throughput is the essential difference in wireless mesh network for longwall coal mine face. A 3-radio architecture of wireless mesh node is presented in this paper in which 2 radios provide up link and down link backhaul functionality and the other radio provides service to clients. Nodes within the interference range of each other can avoid interference through communication over different channels and reduce the bandwidth degradation after multi-hop in backhaul network.
