“…Small-scale spatiotemporal characteristics such as the delay spread, the azimuth/elevation angle spread of arrival and XPD were measured at 25.5, 28, 37.5, and 39.5 GHz for different polarimetric combinations in [30]. In [31], 28 GHz measurement campaigns were conducted in both indoor and outdoor environments in the United Arab Emirates. Massive path loss and direct gain measurements were carried out at 28 GHz in an indoor environment with corridor in [32].…”

Accurate propagation characteristics are essential for future indoor millimeter-wave (mmWave) small cell network planning. This paper presents propagation measurements at 26 GHz and 38 GHz which are important candidate bands for fifth generation mmWave communication. Measurements are conducted in an indoor corridor, as well as a stairwell whose mmWave channel is seldom investigated before. In these measurements, an omnidirectional biconical antenna is used as transmitter and a steerable directional horn antenna is used as receiver. The directional and omnidirectional path loss exponents, shadow factors, cross-polarization discrimination ratios and root-mean-square delay spreads are analyzed for both line-of-sight and non-line-of-sight scenarios in both co-polarization and cross-polarization, and these characteristics are compared for different frequencies and environments. It is found obvious depolarization phenomenon in non-line-of-sight scenario for higher frequency. Compared to the corridor, the stairwell has larger path loss exponents and root-mean-square delay spreads, and the depolarization is also more evident in stairwell. The results in this paper are beneficial to building efficient and robust indoor mmWave communication systems.INDEX TERMS Millimeter-wave, indoor propagation, path loss, cross-polarization discrimination ratio, delay spread.

“…The laboratory environment is composed of workbenches, desks, equipment, tables and enclosed by walls and ceiling made of different materials, and windows. In [93], it was reported that the PLE is identical with free space path loss exponent (FSPLE) based on NB measurements at 28 GHz in indoor laboratory. In [96,97], statistical coefficient of Rician and Nakagami distribution functions for 30 GHz propagation channel using measurement results in a LOS showed that the value of the coefficient varies with the distance between the Tx and Rx, and a good fit was obtained for small scale fading characteristics.…”

“…The PLE and β values are less than the FSPLE value for all frequencies in LOS indoor corridors [35,36,46,72,76,[91][92][93][94][95][98][99][100] as depicted in Table 7. The PLE values are around FSPLE value in large halls as in [107,116,117].…”

The millimeter-wave (mmWave) is expected to deliver a huge bandwidth to address the future demands for higher data rate transmissions. However, one of the major challenges in the mmWave band is the increase in signal loss as the operating frequency increases. This has attracted several research interests both from academia and the industry for indoor and outdoor mmWave operations. This paper focuses on the works that have been carried out in the study of the mmWave channel measurement in indoor environments. A survey of the measurement techniques, prominent path loss models, analysis of path loss and delay spread for mmWave in different indoor environments is presented. This covers the mmWave frequencies from 28 GHz to 100 GHz that have been considered in the last two decades. In addition, the possible future trends for the mmWave indoor propagation studies and measurements have been discussed. These include the critical indoor environment, the roles of artificial intelligence, channel characterization for indoor devices, reconfigurable intelligent surfaces, and mmWave for 6G systems. This survey can help engineers and researchers to plan, design, and optimize reliable 5G wireless indoor networks. It will also motivate the researchers and engineering communities towards finding a better outcome in the future trends of the mmWave indoor wireless network for 6G systems and beyond.

“…Accordingly, this lack of bandwidth will not meet the aspirations of the upcoming 5 wireless system to accomplish high peak data transmission rates up to multi gigabits per second even with complex modulation schemes and multiple-input multiple-output (MIMO) systems [1]- [13]. Because of that and due to the rapid growth in demand for much higher data rates, the research on the millimeter-wave (mmWave) frequency spectrum (30-300 GHz) has been accelerated for the reason that these bands are the candidate for deployment of the 5 cellular network and for satisfying future needs [2], [4]- [7].…”
