“…In the realm of indoor WPAN, the introduction of spatial reuse mode via beamforming utilizing steerable antennas with eight parallel communication links results in a 3-5 times increase in overall millimeter-wave WPAN system throughput compared to traditional time division mode [143]. Addressing robustness against line-of-sight (LOS) blockages is a compelling research domain, where antenna beamforming is anticipated to assume a pivotal role [144]- [146].…”

This paper underscores the paramount significance of through-wall communications by providing a comprehensive exploration of pivotal aspects like wall characterization, relevant technologies, versatile applications, and future prospects. Through-wall communication has the potential of being adopted in diverse fields, from indoor wireless communications, ground penetrating radar, through-wall radar imaging, to even power transmission. To augment the efficiency and reliability of signal detection, a whole variety of tools, such as antenna elements, frequency-selective structures, metasurfaces, and lenses, are exploited. By surveying the landscape of relevant technologies and applications in the existing literature, this paper serves as a beacon for researchers and engineers alike. Furthermore, it extends an invitation for pioneering exploration in this field, advocating the examination of tunable and adaptive systems, as well as the untapped potential of 3D printing in reshaping the future of through-wall communications. INDEX TERMSAntenna arrays, Bow-tie antennas, Frequency selective structures (FSSs), Ground penetrating radar (GPR), Horn antennas, Indoor communications, Lenses, Metamaterials, Metasurfaces, Microstrip antennas, Power transfer, Through-wall communications (TWC), Through-wall power transfer (TWPT), Through-wall radar imaging (TWRI), Vivaldi antennas. and Electronic Engineers (IEEE) [10] and International Commission on Non-Ionizing Radiation Protection (ICNIRP) [11] provide guidelines for power levels considering the safety of humans in the environment. Through-wall communication is employed in many applications like indoor propagation [12]-[17], ground penetration radars (GPR) [18]-[22], through-wall imaging radars (TWIR) [23]-[32], and power transmission through walls [33]-[39]. Stable signal coverage in indoor environments, including walls and other materials, is essential for indoor communications. With the introduction of the Internet of Things (IoT) and smart houses, electromagnetic waves with different operation frequencies propagate in buildings [17], [40], [41]. In these environments, through-wall communication aims to improve the reliability of the signal. Transmission of power through walls is another branch of TWC which has been investigated in literature [42]-[47].
