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
7552034 Method and computer program for use in locating wireless base stations in a mobile communication June 23, 2009
When locating base stations which are wirelessly coupled with each other and establish one or more inter-cell wireless relay routes in a mobile communications system, the heights of directional antennas to be installed at the base stations are determined so as to be different, which
7532629 Multi-hop network for transmission of packets whose size is determined by hop count number May 12, 2009
In a source node of a multi-hop network is provided with a route table in which a number of routes from the node to all destinations are mapped to hop count numbers. In response to a request for transmission of data, the node determines a hop count number from the route table correspondi
7515911 Radio transmission apparatus, routing method, and routing program of radio network April 7, 2009
A task is to automatically carry out directional control of an antenna in parallel with routing in a radio network.In the event that a radio transmission apparatus 100, which is a node configuring the radio network, received a routing packet 200 from the node over the radio network,
