Unmanned Aerial Vehicle (UAV) communications have received considerable attention in recent years as it can be applied to a wide range of applications. To expedite this development, is essential able model and accurately predict the wireless channels UAV communication. Thus, paper, we compare various state-of-the-art empirical large-scale path loss models provide quantitative insights into these models. Based on operating frequency, environment, horizontal distance, altitude, recommend...
The increasing demand for high data rates in the current communication system leads to evolution of 5G technology.Therefore, it is great interest study impact path length and frequency network.This paper presents rain attenuation statistics heavy regions using rainfall collected over three years Kuala Lumpur.From analysis, a 0.2 km terrestrial link less than 5 dB.Furthermore, found that monthly are more significant analysis indicates inter-monsoon season records highest followed by northeast...
Abstract Advanced telecommunication systems are moving toward a high data transfer rate and wider bandwidth. The 5G communication network has recently been implemented for such aims. However, networks operating with frequency (typically above 20 GHz) could lead to impairments because of the atmospheric phenomena mainly precipitation especially heavy rain. To address this, an optimum rain fade margin in Peninsular Malaysia is proposed using 77 sites rain-gauge network, which convert 1-h 1-min...
Abstract The presence of obstacles in the propagation path is a critical factor air-to-ground (AG) communication. behavior wireless signal depends on several variables, such as frequency, building height, elevation angle, and street design. This paper aims to compare three established line sight (LOS) probability model based actual site data, including geometry suburban environment. comparison between these models using data provide guideline for selecting LOS optimistic pessimistic...
