WLAN室内信号路径衰减在OPNET上的仿真研究

Performance analysis of WLAN indoor path loss model implemented in OPNET

准确地测量或预测路径衰减是无线局域网(WLAN)分布设计过程中关键的一环.本文通过对路径衰减经验模型的研究,在OPNET上仿真实现,替换了OPNET提供的自由空间传播模型,为OPNET进一步精确模拟研究室内环境的无线传播提供基础.

In the new era of wireless communication, Wireless Local Area Network has been deployed in various indoor and outdoor places. And indoor range performance is critical in the WLAN deployment. This paper studies the indoor empirical path loss model and implements it in OPNET to improve accuracy in simulation. The comparison with the free space model in OPNET is given. The further study of indoor WLAN modeling in OPNET will be conducted.
