Radio LAN for the information personalization

1. 研制了实验室无线电LANQPSK通信系统和可靠的快速终端节点控制器（TNCs）。数据传输实验在270mhz频率下以154kbps进行。数据包长度对吞吐量的依赖性，与有线链路的比较等进行了检查。无线移动主机协议提出了一种包含无线网络中的路由以及无线网络与有线网络之间的网关的路由协议。这是基于一个移动主机协议，VIP（虚拟IP）。在移动主机协议上的无线电实验一个由无线电主机使用的VIP扩展已经开始使用实验室无线电局域网。利用KA9Q软件包和新闻系统对TCP/IP网络进行业余无线电实验，有助于学生了解TCP/IP协议和无线网络的操作。实验室无线局域网和VIP的扩展对无线移动计算具有重要意义。

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.
