Over 80% of wireless traffic already takes place in buildings. Like water, gas, and electricity, wireless communication is becoming one of the most fundamental utilities of a building. It is well known that building structures have a significant impact on in-building wireless networks. If we seek to achieve the optimal network performance indoors, the buildings should be designed with the objective of maximizing wireless performance. So far, wireless performance has not yet been considered when designing a building. In this paper, we introduce a novel and interdisciplinary concept of building wireless performance (BWP) to a wide audience in both wireless communications and building design, emphasizing its broad impacts on wireless network development and deployment, and on building layout/material design. We first give an overview of the BWP evaluation framework proposed in our state-of-the-art works and explain their interconnections. Then, we outline the potential research directions in this exciting research area to encourage further interdisciplinary research.The research is funded by EUROSTARS Project Build-Wise (11088).
A three-dimensional (3-D) analytical indoor line-ofsight (LOS) probability model is given in this letter. According to the indoor layout of a specific building, the proposed closed-form model can be used to compute the LOS probability in a 3-D environment. The model is validated in both single rooms and a typical office building by Monte Carlo simulations. Moreover, the coverage rate in a typical office building with a 3-D ultra-dense small cells network is evaluated based on the proposed LOS probability model. The numerical results show that the proposed model matches the simulations well in terms of both the LOS probability and the coverage rate.
