“…In [35], the propagation measurements were conducted in the 28 GHz and 73 GHz frequency bands in a typical indoor office environment in downtown Brooklyn, New York on the campus of NYU and a large-scale path loss and temporal statistics was obtained. In [30,33,34,36], extensive propagation measurement campaigns were conducted at 6-38 GHz, which measured path loss and delay spread in indoor corridors and dining rooms. Obtaining this information is vital for the design and operation of future 5G cellular networks that use the mm-wave spectrum.…”

It has been widely speculated that the performance of the next generation based wireless network should meet a transmission speed on the order of 1000 times more than the current cellular communication systems. The frequency bands above 6 GHz have received significant attention lately as a prospective band for next generation 5G systems. The propagation characteristics for 5G networks need to be fully understood for the 5G system design. This paper presents the channel propagation characteristics for a 5G system in line of sight (LOS) and non-LOS (NLOS) scenarios. The diffraction loss (DL) and frequency drop (FD) are investigated based on collected measurement data. Indoor measurement results obtained using a high-resolution channel sounder equipped with directional horn antennas at 3.5 GHz and 28 GHz as a comparative study of the two bands below and above 6 GHz. The parameters for path loss using different path loss models of single and multi-frequencies have been estimated. The excess delay, root mean square (RMS) delay spread and the power delay profile of received paths are analyzed. The results of the path loss models show that the path loss exponent (PLE) in this indoor environment is less than the free space path loss exponent for LOS scenario at both frequencies. Moreover, the PLE is not frequency dependent. The 3GPP path loss models for single and multi-frequency in LOS scenarios have good performance in terms of PLE that is as reliable as the physically-based models. Based on the proposed models, the diffraction loss at 28 GHz is approximately twice the diffraction loss at 3.5 GHz. The findings of the power delay profile and RMS delay spread indicate that these parameters are comparable for frequency bands below and above 6 GHz.

“…The close-in free space reference distance path loss model, with frequency dependent path loss exponent (CIF), is a multi-frequency model that employs the same physically motivated free space path loss (FSPL) anchor at 1 m, as that of the CI model. The CIF model is defined as [36]:…”

“…For different scenarios of terrestrial communications, such studies investigate the characteristics of the channel in angular, Doppler and delay domain. Several studies [3][4][5][6][7][8] have been presented in the literature to study the channel characteristics for mmWave band, mainly at 28 GHz and 38 GHz. In [3], measurements are presented which were conducted for outdoor cellular propagation environments at 28 GHz in New York City; where Path loss, angular statistics, and delay statistics are studied.…”

“…In [6], spatial and temporal characteristics of indoor radio channels for 28 GHz mmWave band are studied; particularly for an indoor office environment. Similarly, in [7], channel measurements are conducted in an indoor corridor radio propagation environment for mmWave range at 19 GHz, 28 GHz, and 38 GHz bands. Various dynamic challenges in addressing the demands of emerging 5G communication networks, demand conduction of an intensive research to study both the large-and small-scale fading statistics of both indoor and outdoor mmWave radio propagation channels.…”

Extension of usable frequency spectrum from microwave to millimeter-wave (mmWave) is one of the key research directions in addressing the capacity demands of emerging 5th-generation communication networks. This paper presents a thorough analysis on the azimuthal multipath shape factors and second-order fading statistics (SOFS) of outdoor and indoor mmWave radio propagation channels. The well-established analytical relationship of plain angular statistics of a radio propagation channel with the channel’s fading statistics is used to study the channel’s fading characteristics. The plain angle-of-arrival measurement results available in the open literature for four different outdoor radio propagation scenarios at 38 GHz, as well as nine different indoor radio propagation scenarios at 28 GHz and 38 GHz bands, are extracted by using different graphical data interpretation techniques. The considered quantifiers for energy dispersion in angular domain and SOFS are true standard-deviation, angular spread, angular constriction, and direction of maximum fading; and spatial coherence distance, spatial auto-covariance, average fade duration, and level-crossing-rate; respectively. This study focuses on the angular spread analysis only in the azimuth plane. The conducted analysis on angular spread and SOFS is of high significance in designing modulation schemes, equalization schemes, antenna-beams, channel estimation, error-correction techniques, and interleaving algorithms; for mmWave outdoor and indoor radio propagation environments.
