| Abstract: | In this paper, the authors investigate dynamic channel allocation techniques in BWA system and introduce a new upper service model, namely PARETO model, according to the characteristics of the data network. Then the authors analyse the features of the BWA channel and put forward a kind of dynamic channel allocation scheme based on SNR measured. The experiment result indicates this technique can reduce the service hotspot and raise the data throughput of the entire communication system. |
