    • PROBLEM TO BE SOLVED: To provide a technique for maintaining a predefined transmission quality in a wireless Metropolitan Area network (MAN). SOLUTION: Routers connected to a plurality of LANs are interconnected to one or more transceivers via wireless links, respectively. Each router stores a table representative of the topology of the MAN and receives detected information representing the quality of the wireless links and network traffic loads. The router adapts the manner of transmission and the path of transmission according to the information. For example, a strength of a signal received over a wireless communication link is periodically monitored for maintaining the strength within a predefined range by adjusting the transmission power. An error rate for the data received over the link is also monitored. If the received signal strength remains below the predefined range despite the transmit power having been adjusted to the maximum allowable level and if the error rate approaches a predefined limit, one or more techniques are selectively employed to reduce the error rate while maintaining a sufficiently high network throughput.

    • 要解决的问题:提供一种在无线城域网(MAN)中维持预定传输质量的技术。 解决方案:连接到多个LAN的路由器分别经由无线链路互连到一个或多个收发器。 每个路由器存储表示MAN拓扑的表,并接收表示无线链路质量和网络流量负载的检测信息。 路由器根据信息调整传输方式和传输路径。 例如,通过调整发送功率来定期监视通过无线通信链路接收的信号的强度,以将强度保持在预定范围内。 还监视通过链路接收的数据的错误率。 如果接收到的信号强度仍然低于预定范围,尽管传输功率已经被调整到最大允许电平,并且如果误码率接近预定极限,则选择采用一种或多种技术来降低错误率,同时保持足够高的网络 吞吐量。 版权所有(C)2010,JPO&INPIT
