Radio LAN for the information personalization

1.研制了实验室无线LANQPSK通信系统和可靠的快速终端节点控制器(TNC)。数据传输实验在270 MHz上进行，传输速率为154kbps。检查了吞吐量的分组长度依赖关系、与有线链路的比较等。RAIO移动主机协议提出了一种包括无线网络中的路由以及无线和有线网络之间的网关的路由协议。这是基于移动主机协议VIP(虚拟IP)的。关于移动主机协议的无线电实验无线电主机使用的VIP扩展已经开始使用实验室无线电局域网。利用KA9Q软件和一个新闻系统对基于HAM无线电的TCP/IP网络进行了实验，有助于学生了解TCP/IP协议和无线网络的运行情况。信息的个性化实验室无线电局域网和VIP的扩展对于无线电移动计算可能是重要的。

1. Laboratory radio LANQPSK communication system and reliable fast TNCs (Terminal Node Controllers) are developed. Data transfer experiments are performed at 154 kbps on 270 MHz. The packet length dependence of the throughput, a comparison with a wired link etc. are examined.2. Raio mobile host protocolA routing protocol including routing in a radio network as well as a gateway between radio and wired networks is proposed. This is based on a mobile host protocol, VIP (virtual IP).3. Radio experiment on a mobile host protocolAn extention of VIP to be used by radio hosts has started using the laboratory radio LAN.4. Experiment on TCP/IP over ham radioThis experiment on TCP/IP network over ham radio using the KA9Q software package and a news system is useful for students to understand the TCP/IP protocol and the operation of the radio network.5. Personarization of informationThe laboratory radio LAN and the extention of VIP could be important for the mobile computing by radio.
