Abstract (in Japanese) (See Japanese page) 
(in English) NTT carries out research and development of "Multi radio proactive control technology (Cradio ®)" which offers optimum radio access for maintaining communication quality by grasping and predicting the radio environment which changes every moment in real time with the aim of offering natural communication environment which does not make the user conscious of the radio network. Cradio is a technology group composed of several technologies, and it is mainly composed of three elemental technologies: (1) wireless environment grasping and visualization technology for grasping the present wireless environment, (2) wireless network quality prediction technology for anticipating the wireless environment around the user, and (3) wireless access design and control technology corresponding to the requirement according to the predicted quality. By these technologies, it aims at realizing the communication experience which "does not make the connection conscious" by the network autonomously corresponding to the change according to the demand of user and application. In this presentation, we introduce each elemental technology which constitutes Cradio, and introduce actual introduction cases using these technologies..
