The Design of WLAN Videophone Based on WAPI

This paper describes the design and realization of a kind of WLAN video telephone based on WAPI. The hardware system consisted of two parts: application processing subsystem and base band processing subsystem. Take SIP as the call control protocol, H.264 as the video codec and G711 as the audio codec. Using WAPI as the security mechanism of wireless data transmission, and solved the security problem of password and guarantee the quality of the video and audio service.
