- As the market for high-speed Internet and cellular communication services reaches maturity, communication services have shown a limit to growth based on the number of subscribers. On the other hand, demand for the wireless Internet service is growing explosively. Recently, much attention has been paid to portable Internet as a solution not only to surpass limits of high-speed Internet, wireless LAN, and cellular communications, but also to accommodate increasing demands for wireless Internet services. In this article, we introduce the Wireless Broadband Internet (WiBro), considered the first system that bridges the wired and wireless realm by providing high-speed portable Internet access anywhere at anytime at low access cost and high data rates. An overview of the WiBro system architecture and its services are given, followed by the design concepts and the structure of the WiBro Access Terminal, which plays an important role in delivering user-friendly wireless Internet access. © 2006 IEEE.
