Abstract
The characteristics of indoor dense environment required accurate modeling. The multipath effects due to different obstacles with different materials and dimensions make the behavior of the propagated signal unpredictable. In this paper, a reliable ray tracing simulator is used for assessing the performance of WLAN based on the 802.11n dual-band system, was a real lab scenario is adopted as a complex indoor environment. The effects of different parameters are investigated. They are objects materials, object dimension, and frequency to address the effects of diffraction and reflection phenomena on the received power. Object materials are analyzed and this paper verifies that metal object, especially with large dimensions has significant effects on signal strength fluctuations due to their electrical properties. In addition, small object effects can be neglected at the cost of 4.86 dBm and 5.27 dBm losses at 2.4 GHz and 5 GHz respectively to reduce the simulation computational time. On the other side, the results show that the propagation signal is prone to more attenuation at a higher frequency due to path loss increasing.
