A method and a device for processing wireless body area network data, the method is applied to a processing device for wireless body area network data and comprises receiving or generating sampled value reference ranges receiving sampled data from an acquisition device of wireless body area network data, and judging a sampled value reference range to which the sampled data belong according to a sampled value of the sampled data and processing the sampled data according to the sampled value reference range to which the sampled data belong. Through the embodiments of the present document, degrees of importance of the sampled data can be automatically differentiated and the data processing efficiency is improved under the situation of limited resources.
