本文论述了一种新的方法来控制的传播环境在室内场景中使用智能墙。智能墙是位于建筑物内的传统墙壁，但配备有有源频率选择表面和传感器。智能墙可以被设计为在高容量移动的无线电系统内工作的协作基础设施的自配置和自优化自主部分。本文展示了如何使用这种表面来调整墙壁的电磁特性，以响应交通需求的变化，使用传感器网络进行监测，从而控制建筑物内的传播环境。一些潜在的问题（主要是控制覆盖范围和干扰）有关的增加使用的无线系统内部和外部的建筑物进行了讨论，并提出了可能的解决方案，使用智能墙与主动FSS。智能墙对系统性能的积极影响，并从模拟得到的结果显示和讨论。
This paper deals with a new approach to the control of the propagation environment in indoor scenarios using intelligent walls. The intelligent wall is a conventional wall situated inside a building, but equipped with an active frequency selective surface and sensors. The intelligent wall can be designed as a self-configuring and self-optimizing autonomous part of a collaborative infrastructure working within a high-capacity mobile radio system. The paper shows how such surfaces can be used to adjust the electromagnetic characteristics of the wall in response to changes in traffic demand, monitored using a network of sensors, thereby controlling the propagation environment inside the building. Some of the potential problems (mainly controlling coverage and interference) relating to an increased usage of wireless systems both inside and outside buildings are discussed and possible solutions using intelligent walls with the active FSS are suggested. The positive influence of intelligent walls on system performance is shown and results obtained from the simulations are shown and discussed.
