According to the latest development of telecommunications technology, radio waves are currently used for various systems such as broadcasting, cellular phone, WLAN, BWA, etc. Radio communications are accordingly indispensable for our daily life.
Especially, in Japan, the number of subscribers of cellular and PHS are currently more than 100 M and still increasing. In addition, cell phone services are also continuing to be advanced, e.g., internet access, e-money, music download, seasonal ticket, digital broadcasting and so on. Taking account of such current situation, MIC, Ministry of Internal Affairs and Communications, is making effort to prepare regulations corresponding to user demand for future radio communication systems.
This presentation will introduce the latest radio communications policies conducted by MIC.

The Ministry of Internal Affairs and Communications (MIC) has a plan to grant the licenses of Broadband Wireless Access (BWA) services, so-called WiMAX services, to telecommunication carriers selected after this autumn. The WiMAX services will start from Tokyo, Nagoya, and Osaka in 2008, and will be gradually extended to other areas. The population coverage will be 50% by 2012, leading to an ubiquitous network society. A society where network access is available ″for anyone at any time and any place″.
In addition, the WiMAX services are expected to be solutions for elimination of the geographic digital divide.
This presentation describes recent progress and perspectives on the WiMAX services.

For realizing broadband dependable wireless next generation network (Wireless NGN), it is important that the several wireless systems are integrated seamlessly.
In the presentation, the product of information technology (IT) program (RR2002 ; Ministry of Education, Culture, Sports, Science and Technology of Japan) ″Development of mobile internet terminal for next generation″ will be presented. We have developed the following three technologies ; (1) 324Mbit/s 5GHz-band wireless local area network (LAN) terminal, (2) 10mm⟨-size 1Gbit/s 60GHz-band wireless personal area network (PAN) terminal using 3- dimentional system-in-package (3-D SiP) technology, and (3) Mobile broadband wireless access (MBWA) trial in Sendai area. Finally, I will propose a concept of the dependable Wireless NGN.
