An effective path loss modeling approach for 5G millimeter wave connectivity

In order to support the over 11 billion mobile-linked devices brought about by the internet of things idea, the current development in the wireless communication system is necessitated by society’s desire for information sharing and requires pervasive wireless connectivity. The lack of capacity has frequently hampered modern mobile phone communication service providers’ efforts to offer excellent services on wireless gadgets via mobile high-speed networks. The constraint is caused by prevailing worldwide communication structures, which enable bandwidths ranging from 700[Formula: see text]MHz to 2.6[Formula: see text]GHz. Millimeter wave (mmWave) ranges provide a large amount of capacity and inspire the development of next-generation communication networks. Fifth-generation wireless connections will take advantage of the massive amount of spectrum that exists in the millimeter wave frequency spectrum. As a result, for interior spaces where implementation is most likely, an accurate as well as simple path loss model (PLM) is essential. The paper describes assessing campaigns with specific transmitter-receiver arrangements at 38[Formula: see text]GHz employing a custom-designed channel sounder utilizing a line-of-sight (LOS) communication circumstance. The antenna polarization measurement of path loss (PL) data was in vertical to horizontal (V–H) orientation. In light of the collected data, the successful implementation of an improved single-frequency close-in (CI) directional PLM is assessed. The use of the CI large-scale PLM is backed up by an extensive investigation as well as an evaluation of propagation methods. The evaluated findings indicate that the improved CI PLM used in this work surpasses the CI reference distance model, especially along a distance of between 8 and 10 m in the 38 GHz frequency band, which takes into account the transmission wave guiding effect in the interior hallway.
