This paper outlines technical trend of multimedia mobile and broadband wireless access systems utilizing comprehensive concept and new categorization of wireless access. It is pointed out that mobile communications have much potential market in future high-speed data or IP (Internet Protocol)-based traffic. Categorization of three kinds of wireless access is presented based on the definition adopted by the Radiocommunication Sector in ITU. IMT (International Mobile Telecommunications)-2000 and broadband wireless LANs (Local Area Networks) each representing mobile and nomadic wireless access will bring about a turning point to a new era that wireless communications become dominant media in access networks. With this perspective technical subjects, spectrum consideration and deployment scenario for these systems are discussed.
