建筑物内复杂的无线电传播环境通常需要在设计建筑物内无线网络时进行特定地点的无线电规划/建模/测量。随着成本极低的分布式天线硬件的出现，用大量天线元件覆盖建筑物（“饱和方法”）在经济上变得可行。我们研究了这种情况下的特征无线电分布统计数据（无线电功率和延迟扩展），发现在每单位面积有“足够大”数量的天线元件的情况下，这些无线电统计数据接近某些通用分布，这些分布在很大程度上独立于特定的平面图，并且可以准确预测，无需调用可调整的参数，仅使用一些易于确定的“全局”建筑参数。与实验测量结果的比较得出了很好的一致性。
The complex radio-propagation environment inside buildings often necessitates site-specific radio planning/modeling/measurements in designing an in-building wireless network. With the emergence of very-low-cost distributed-antenna hardware, it becomes economically feasible to blanket a building with a large number of antenna elements (the "saturating approach"). We investigate the characteristic radio distribution statistics (for both radio-power and delay-spread) under this scenario, and found that with a "sufficiently large" number of antenna elements per unit area, these radio statistics approach certain universal distributions which are largely independent of the specific floor-plan, and which can be accurately predicted, without invoking adjustable parameters, using only a few easily-determinable "global" building parameters. Comparison with experimental measurements yields excellent agreements.
