The demand amount of circulating information in the Information Society is increasing by leaps and bounds. Therefore setting up of user-friendly Integrated Services over the broad-band and high-speed communication networks should be preceded for responding to the demands of time.
Optical Fiber communication technique which is backbone of broad-band communication networks has been used since 1980's and established technical and economical excellence in connecting nations via relay communication networks.
The technique not only solved high traffic problem of the existing telephone circuits, but also observed excellent digital signal processing and made possible to integrate communication and computer networks.
At present it is a building block in constructing integrated service broad-band ISDN which integrated wired and wireless networks. So the development of integrated access networks, a new concept, enabling integration of wireless communication techniques, is the need of time.
The Center for Integrated Access Systems (CIAS) has been founded to pursue the demand and technical excellence on the integrated services of the Information Society.
The department of Information and Communication of Gwangju Institute of Science & Technology (GIST) is the root of CIAS, which is instigated by the remarkable development of computer technologies and semiconductor in the last half century and a stimulus of a large-scale transition, from the present industrial society to a new information society expected in the 21st century.
This new information society will enable the transfer and distribution of information and knowledgable/learned individuals to anyone around the world via various communication media.
Taking into consideration the needs of the new society, the CIAS has set three major objectives:
Educating research manpower for the development and the management of integrated communication networks, which will lead this new society towards excellent innovations.
Carrying out research programs of broad-band communication networks and their management for integration of data, voice and video media.
Development of basic core technologies such as photonics, radio communications, signal processing, and human interface at the levels of devices, components, systems, and software.
The CIAS which is a part of GIST is fundamentally supported by the Korean Government, via Ministry of Science and Technologies, and Ministry of Information and Communication.
The Center has exchanged letters of partnership with such leading Korean companies as Dacom Ltd., S.K. Telecom Ltd., Haitai Electronics Co Ltd., Hanhwa Information and Communications Co Ltd.
The center has also partnered with international research institutes as UbiCom team with TUD, The Netherlands, Center for Wireless Communications, University of Mississippi and Half Dome System in California.
