Research on key issues in future wireless network

Based on the investigation of the phenomenon in complex networks, this paper proposed some important facing problems in future wireless networks, that is, it is difficult to fully predict the trend of wireless networks from the perspective of application requirements and the technology development. Therefore, with the hot spots in future wireless network, a research framework was proposed which was made from three levels including philosophy, science of system and technologies. In the study of this framework, three levels of contents are proposed, that is, service models research which related to social science, the network control model research which related to system science, and the transmission model research which related to nature science. Some key technologies are deplored based on the methodology proposed in this paper.
