摘　　要：目前,基于最新城域网标准IEEE802.16a的无线宽带接入产品日趋成熟,高速无线以太网桥工作在5.8GHz频段,支持点对点和点对多点的网络结构,空中速率高达72Mbit/s,最远通信距离可达50km,完全能满足图像、语音、数据的传输要求。文章介绍了基于5.8GHz无线宽带接入方式设计的无线图像、语音、数据综合监控系统,对其原理和各部分结构进行了详细说明。Now the products of wireless broadband access base on the IEEE802.16a standard are more and more mature. High-speed wireless Ethernet bridge ,which operates on 5.8GHz band, supports the PTP and PMP frameworks of network, provide high speed through space up to 72Mbit/s and the farthest communication distance up to 50Km, can meet completely the requirements of image, audio and data transmission. This paper introduces a wireless integrated monitoring system for image , audio and data transmission based on the 5.8GHz broadband wireless access mode. The principle and components of the system are also explained in detail.
