    • A data transmission network comprises two groups of nodes (1; 2, 3, 4), a radio interface associated to each group and connected to the nodes (1) of the group and a radio path (5) between the two radio interfaces (9), in which several groups (1412, 1413, 1414) of virtual paths (15) of warranted bandwidth are transmitted between one node (1) of the first group and one node (2, 3, 4) of the second group. The sum of the bandwidths warranted to the groups (1412, 1413, 1414) of virtual paths does not exceed the total bandwidth of the radio path (5) when operated in a transmission mode referred to as basic mode. The radio interfaces (9) support several physical transmission modes of different bandwidths and are adapted to detect the transmission quality of the radio path (5) and to operate, the transmission quality of the radio path (5) permitting, the radio path (5) in a transmission mode of higher bandwidth than that of the basic mode and to use the bandwidth difference between the used mode and the basic mode for bandwidth need of the groups of virtual paths in excess of the warranted bandwidth.
    • 数据传输网络包括两组节点(1; 2,3,4),与每个组相关联并连接到该组的节点(1)的无线电接口以及两个无线电接口之间的无线电路径(5) 9),其中在第一组的一个节点(1)和第二组的一个节点(2,3,4)之间传送有保证带宽的虚拟路径(15)的若干组(1412,1413,1414)。 在被称为基本模式的传输模式中操作时,对虚拟路径的组(1412,1413,1414)的带宽总和不超过无线电路径(5)的总带宽。 无线电接口(9)支持不同带宽的几种物理传输模式,适用于检测无线电路径(5)的传输质量,并操作无线电路径(5)的传输质量,允许无线电路径(5) ),并且使用超过保证带宽的虚拟路径组的带宽需求的使用模式和基本模式之间的带宽差。
