With the rapid development of society?informatization, the Wireless Local Area Networks (WLAN) technology is increasingly popularizing. Used as the important places for intelligent terminals such as computers, mobile phones, televisions and so on to connect to wireless internet, the buildings have complicated and diverse internal structures and facilities. In order to reasonably design and apply WLAN, the characteristics of wireless channels in buildings should be deeply analyzed and understood. According to the characteristics of WLAN technology and the main environment features in buildings, the propagation loss data of wireless channels and the prediction model are analyzed in detail based on the radiowave propagation mechanisms, and the problems which should be concerned in engineering application are pointed out.
