Complex building structures constrain indoor wireless communications. The significant dependence between the indoor wireless network performance and the building structures can be considered as an intrinsic property of a building, which means that the building has to be designed to achieve desirable indoor wireless network performance. The power gain (PG) and the interference gain (IG) have been defined as the figures of merit (FoMs) to evaluate the wireless performance of a building. Employing open space as the benchmark, the PG and the IG respectively quantify the effective change of the intended signal power and the undesired power, i.e., the interference and thermal noise power, received in a targeted user equipment (UE) location due to the presence of the building. In this paper, a tractable approach is proposed to obtain the PG and the IG with a partition-based path gain model. It enables the PG and the IG to capture the impact of both building materials and the building layout on indoor wireless network performance. Numerical results show that the analytical models in closed-form expressions facilitate the wireless performance assessment to a given building computational-efficiently. This work is a critical complement to the initial framework of the building wireless performance (BWP) evaluation. The proposed method can be employed in future wireless-friendly building design.

基于分区的建筑无线性能分析评估

复杂的建筑结构限制了室内无线通信。室内无线网络性能与建筑结构之间的显着相关性可以被认为是建筑的固有属性，这意味着建筑的设计必须达到理想的室内无线网络性能。功率增益 (PG) 和干扰增益 (IG) 已被定义为用于评估建筑物无线性能的品质因数 (FoM)。以开放空间为基准，PG和IG分别量化目标用户设备（UE）位置由于存在而接收到的预期信号功率和非预期功率的有效变化，即干扰和热噪声功率的建筑物。在本文中，提出了一种易于处理的方法来获得具有基于分区的路径增益模型的 PG 和 IG。它使 PG 和 IG 能够捕获建筑材料和建筑布局对室内无线网络性能的影响。数值结果表明，封闭式表达式中的分析模型有助于以高效的计算方式对给定建筑物进行无线性能评估。这项工作是对建筑无线性能 (BWP) 评估初始框架的重要补充。所提出的方法可用于未来的无线友好建筑设计。数值结果表明，封闭式表达式中的分析模型有助于以高效的计算方式对给定建筑物进行无线性能评估。这项工作是对建筑无线性能 (BWP) 评估初始框架的重要补充。所提出的方法可用于未来的无线友好建筑设计。数值结果表明，封闭式表达式中的分析模型有助于以高效的计算方式对给定建筑物进行无线性能评估。这项工作是对建筑无线性能 (BWP) 评估初始框架的重要补充。所提出的方法可用于未来的无线友好建筑设计。
