HIPERLAN/2和802.11a是工作在5GHz频段的两种高速无线局域网的协议标准。论述了两种标准的物理层的结构,通过软件仿真对物理层的性能进行了分析;同时也讨论了两种标准的区别以及由此引起的对吞吐量的影响。
HIPERLAN / 2 and 802.11a are two high-speed wireless LAN protocol standards operating in the 5GHz band. The structure of two standard physical layers is discussed. The performance of the physical layer is analyzed by software simulation. The differences between the two standards and the consequent impact on the throughput are also discussed.
