The goal of this work is to gather the basic experimental data and knowledge to build this CAD tool. Then, it describes its initial features, experience and results that we have achieved so far. The paper is organized as follows. First, the related work section presents the studies and empirical models that describe the power losses in a wireless network depending on the material. The section also presents the different disciplines involved in the development of an AmI system. Then, the importance of obtaining a completely ubiquitous system with the integration in furniture is highlighted in Section 3. Later, the.
