  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.
