Performance Analysis of Radio Propagation in 5G Networks for Line of Sight (LOS) and Non-Line of Sight (NLOS) Environments

Abstract

 5G connectivity will be used in Malaysia as part of a plan to upgrade the nation's digital infrastructure. As stated by the Malaysian Communications and Multimedia Commission @ K-KOMM, the country is planning to adopt 5G in multiple stages, with the primary stage takes on the improvement of the country's present 4G connectivity, while the secondary stage is transitioning to 5G by 2022. (MCMC). The 3.5 GHz band is the main focus of 5G mobile networks due to the increasing capacity demands. It is a difficult undertaking, though, because a 3.5 GHz higher frequency range produces a larger path attenuation/path loss. Consequently, it is crucial to measure the signal strength path attenuation for figuring out the frequency band's viable coverage. This study measured the received power and path attenuation/path loss propagation by taking two main parameters; the transmitter distance (Tx) and receiver distance (Rx) in both situations (Line-of-Sight (LOS) & Non-Line-of-Sight (NLOS)) to assess the results. Both of the receiver (Rx) and transmitter (Tx) distances increased by 5 meters for every measurement taken starting from 10 up till 55 meters in both situations to measure the 5G networks radio propagation. According to the measurement results, the route loss rises as transmitter and receiver distances widen while received power declines. As conclusion, increased route loss affects the received power of radio propagation in 5G networks, thus, it can be determined that the ranges for distance between 5 and 55 metres is appropriate to be develop for both of the situations, in LOS and NLOS. The findings of this study can be used in Malaysia as a standard for field tests and interference mitigation methods.(Abstract)
