Abstract:
1. A wireless network relay apparatus, which is equipped with a plurality of line terminating devices corresponding to a plurality of communication lines and which performs line limitation associated with an Adaptive Modulation Radio function, said wireless network relay apparatus comprising: a traffic measuring part configured to measure traffic, passing through the plurality of line terminating devices, in a plurality of directions, thus recording total traffic; a modulation scheme detecting part configured to detect whether or not a modulation scheme is changed due to the Adaptive Modulation Radio function in a wireless area; a modulation scheme judging part configured to specify the line terminating device of the communication line corresponding to the wireless area whose modulation scheme is changed and to judge whether or not a local modulation scheme should be changed; a modulation scheme determining part configured to determine a desired modulation scheme based on the recorded traffic with the specified line terminating device when it is judged that the local modulation scheme should be changed; and a modulation scheme changing part configured to change the local modulation scheme with the desired modulation scheme.
