Outdoor Propagation Channel Investigation at 26 GHz for 5G mmWave Communication

The millimeter wave (mmWave) frequency spectrum is being considered as the most promising communication systems to fulfill the bandwidth requirements for the next-generation wireless network. However, the mmWave frequency band has encountered several issues like fading, scattering, atmospheric absorption, and penetration losses as compared to the currently using frequency spectrum, which is under 6 GHz. Therefore, optimizing the propagation channel path at the mmWave band is seemed to be the only solution, which can help the operators to distinguish the signal behavior before practically implement the 5G networks. In this regard, this study aims to analyze the propagation characteristics for 26 GHz frequency band for the outdoor Single Side Parking (SSP) and Double Side Parking (DSP) environment. It utilizes the most potential propagation path loss models i.e., Close-In (CI) and Floating Intercept (FI). The results prove that the CI model can produce better results and delivers higher network performance as compared to the FI model.
