Abstract
Indoors wireless propagation effects in the context of positioning are still not deeply understood or reported in the existing literature. For an indoor localization system based on Received Signal Strength Indicator measurements, deriving suitable path loss models with adequate shadowing or shadow fading modeling is of utmost importance in order to be able to build low complexity positioning estimators. In this paper we analyze in depth the basic path loss and shadowing models and their parameters, based on extensive measurement campaigns with WLAN and cellular signals. We also discuss the similarities and differences between cellular and WLAN wireless propagation models.
室内无线传播在定位环境下的影响在现有文献中还没有被深入理解或报道。对于基于接收信号强度指标(Received Signal Strength Indicator)测量的室内定位系统，为了能够构建低复杂度的定位估计器，推导合适的路径损失模型并进行适当的阴影或阴影衰落建模是至关重要的。在本文中，我们深入分析了基本的路径损失和阴影模型及其参数，基于广泛的测量活动与无线局域网和蜂窝信号。我们还讨论了蜂窝和WLAN无线传播模型之间的异同。
