Abstract

To build a stable wireless communication system in an indoor environment, it is necessary to perform highly accurate simulations of radio wave propagation characteristics. The ITU-R Recommendation P series, especially ITU-R P.1238, lists estimation models for propagation loss in indoor environments under various conditions. However, there are a few cases in which propagation loss has been measured at various frequencies in the same building and under the same conditions. In these cases, necessary parameters may not be described, meaning that simulation cannot be easily performed. In this paper, we measure the radio wave propagation characteristics on the same floor and across floors for the 922 MHz to 28 GHz frequency band, which is often used in office spaces. We then apply a path loss model to each frequency and calculate the coefficient of office environment ( $N$ ) and inter-floor attenuation $(L_{f}(n))$ .
办公室环境中 922 MHz 至 28 GHz 的路径损耗模型
要在室内环境中建立稳定的无线通信系统,就必须对电波传播特性进行高精度模拟。ITU-R 建议 P 系列,尤其是 ITU-R P.1238 列出了各种条件下室内环境传播损耗的估算模型。然而,在少数情况下,传播损耗是在同一建筑物和相同条件下以不同频率测量得到的。在这些情况下,可能无法描述必要的参数,这意味着无法轻松进行模拟。在本文中,我们测量了办公空间常用的 922 MHz 至 28 GHz 频段在同一楼层和跨楼层的无线电波传播特性。然后,我们对每个频率应用路径损耗模型,并计算办公室环境系数 ($N$) 和楼层间衰减 $(L_{f}(n))$。
