摘　　要：WiBro是当前最新的移动宽带无线接入技术之一,它是由韩国业界开发的一项本土技术。WiBro可看作是移动WiMAX,虽然其技术与标准尚处于不断变化之中。给出了WiBro技术的发展历程和技术定位,提出了WiBro系统的基本构成,详细分析了WiBro系统性能(包括频谱范围、数据速率、QoS、双工模式和调制方法),最后阐述了WiBro技术的应用现状。WiBro is one of the newest mobile broadband wireless access being developed by the Korean telecom industry. WiBro can be thought of as mobile WiMAX,though the technology and its exact specifications will change as it undergoes refinements throughout＇its preliminary stages. This paper presents the development history and technical orientation of WiBro, then proposes the architecture of WiBro system. Furthermore,It analyzes the performance of WiBro including spectrum range, coverage,data rate, QoS,duplexing mode and moduiation method. In conclusion, the status quo of WiBro application is proposed.
