摘要： A radio network can select a route of minimum path loss among entire relay routes and can set the relay route so as to satisfactorily resist interference. The radio network has a core node connected to a wired network, relay nodes each relaying at least one of a down-link data packet transmitted from the core node and an up-link data packet directed toward the core node, and a terminal station capable of transmission and reception of data packets with both the core node and the relay node. The relay node has total path loss optimized to be minimum between relay nodes included in a relay route of the data packet or between the relay node and the core node or both.

摘要： The above base-station cell design method is for sequentially adding base stations, and a technique of which throughput is few is employed for a radio-wave propagation characteristic evaluation to be made in this addition, and a technique of which the throughput is much, but which is of high-precision, more specifically, a technique such as the ray tracing is applied for the radio-wave propagation characteristic evaluation to be made after addition. The result of the high-precision radio-wave propagation characteristic evaluation to be made after this addition is put to practical use for estimating an interference quantity in selecting the arrangement location of the base station to be added newly. This allows the quantity of the radio wave analytic processing, which accounts for a large majority of the base-station cell design processing, to be reduced, thus enabling a fast base-station cell design.

摘要： A control packet is broadcast over a route, containing first and second metric values of different transmission characteristics of the route. At a local node, control packets from multiple nodes are received and examined for their source. If the packets are received from upstream nodes, the metrics of the received packets are updated, the second metric is weighted and summed with the first metric to produce a number of combined metrics and a minimum value of the combined metrics is detected. One of the routes having the detected value is selected as a route to an upstream node. If the control packets are received from downstream nodes, the second metric is weighted and summed with the first metric to produce a number of combined metrics and a smaller values of combined metrics are detected corresponding in number to usable antennas and routes of the detected values are selected.
