“…In addition, Lee et al also extended the ITU-R P.1411 (below referred to as P.1411) model to include NLOS, which reasonably explains propagation along street roads where low-height antennas are located [127]. Moreover, Inomata et al used the measured data to add a correction factor to the P.1411 model to make it suitable for a street scenario [129].…”

The radio channel model is a major factor supporting the whole life cycle of the terrestrial radio system, including the demonstration, design, validation, operation, and so on. To improve the spectrum sharing and spectral efficiency in terrestrial radio services, we analyze three types of path loss models in detail: deterministic, empirical, and semi-empirical models, to meet the requirements of path loss modeling for supporting traditional band expansion and reuse. Then, we conduct a comparative analysis based on the characteristics of the current models. Furthermore, a preview of the future terrestrial path loss modeling methods is provided, including intelligent modeling processes and multi-model hybridization methods. Finally, we look forward to the potential technology that can be used in future wireless communication, such as terahertz communication, reconfigurable intelligent surface technology, and integrated communication and sensing technology. The above research can provide a reference for the development of terrestrial radio channel modeling, promoting the technologies of terrestrial channel modeling. We hope this paper will stimulate more interest in modeling terrestrial radio channels.

“…For urban environments, we developed a model by deriving dominant path loss characteristics for three areas in which waves sent from a transmitter (Tx) to a receiver (Rx) are either visible or invisible: a lineof-sight (LoS) area, a non-line-of-sight (NLoS) area, and a corner (i.e., an intersection) area that is a transition area between LoS and NLoS areas [1]. The respective path losses in these areas are indicated as L LoS , L att , and L C , as seen in Fig.…”

To design coverage areas for wireless communication systems and evaluate the performance of the systems, it is necessary to develop a path loss model that can be used for the systems' frequency bands. The fifth-generation mobile communication system (5G) is expected to use high frequency bands above 6 GHz. Therefore, developing a path loss model for wireless access communication systems using high frequency bands has become a pressing issue. NTT Access Network Service Systems Laboratories has developed path loss models for the 20-40 GHz bands that are suitable for use scenarios of mobile phones and wireless local area networks. This article introduces the developed models.

“…Measurement and analysis results for the path loss characteristics in the line of sight (LoS) area of an urban street microcell environment are shown when considering frequency bands from 800 MHz to 37 GHz [2]. Although various applications and services can be provided in indoor scenario thanks to smartphones, it has not been studied over a plurality of frequencies in the outdoor to indoor (O2I) propagation which is one of typical scenarios in 5G systems.…”

Recently, the next generation (5-th generation: 5G) mobile communication systems have been actively investigated all over the world, in order to satisfy the strong demand for the faster and larger data communication. In 5G systems, not only UHF band but also SHF/EHF bands have been attracted much attention. Hence, frequency characteristics of radio propagation path loss have been studied. We have previously investigated outdoor to indoor (O2I) propagation characteristics in the 2.2 GHz band, and a modified path loss model instead of 3GPP model has been proposed. In this paper, in order to investigate frequency characteristics in terms of O2I propagation, the received power is measured for O2I propagation when considering 0.8, 2.2 and 4.7 GHz bands. Moreover, we investigate O2I propagation characteristics for different frequency bands by using O2I factor which denotes coefficient versus transmit distance with logarithm expression when considering O2I propagation. Moreover, we consider O2I factor which is calculated by the least square approximation.
