内容摘要

The IEEE 802.16 standard, commonly known as WiMAX, is the latest technology that has promised to offer broadband wireless access over long distance. Since 2001 WiMAX has evolved from 802.16 to 802.16d for fixed wireless access, and to the new IEEE 802.16e standard with mobility support. In this paper, we provide an overview of the state-of-the-art mobile WiMAX technology and its development. Next, we focus our discussion on deployment scenarios and performance analysis of mobile WiMAX in Vietnam, a developing country with fast growth in Telecommunications.In practice, mobile WiMAX network planning (IEEE Std 802.16e) is described by using GENEX U-net. The system level simulations scenarios (channel models, frequency reuse planning, system loading, etc) will be introduced. Evaluated performance of mobile WiMAX system through fully planning by various parameters of multi-cellular deployment will be presented and discussed.
