Information and its effective delivering means are becoming more and more important in todays world. Video-conferencing is a highly effective means to deliver information since it is interactive. This thesis studies the packet-radio- networking technology that can be used to support video-conferencing applications. The popular networking protocols, i.e. the Amateur X.25 AX.25, the Transport Control Protocot Intemet Protocol TCPIP, and other protocols, widely used in packet radio technology are described. By using the File Transfer Protocol FTP of the TCPIP standard, the average speed and time of various file sizes across a half-duplex radio channel, a full-duplex emulated-radio channel, and a RS-232 link were collected and analyzed. Finally, comparisons were made among channels, including the effects of an additional routing node.
