Abstract : Information and its effective delivering means are becoming more and more important in today's 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 (TCP/IP), and other protocols, widely used in packet radio technology are described. By using the File Transfer Protocol (FTP) of the TCP/IP 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.
