Abstract

5G networks are expected to use the Millimeter Wave (mmWave) frequency band and this frequency provides wider bandwidth allowing a better quality of service to be offered to the users. However, the mmWave frequencies may lead to a higher path loss due to several factors including blockages,rain and atmosphere. Therefore, to allow optimal positioning of the 5G base stations, the study of path loss model in this 5G mmWave frequencies is crucial. This paper investigates the 5G path loss models as well as their parameters that are most suitable for cross-polarized antennas under rural macrocell environment in Malaysia. Path loss models namely Close In Free Space Reference Distance Path Loss Model (CI) model, and Alpha Beta Gamma (ABG) or Floating Intercept (FI) Model along with their parameters achieved from the previous studies were evaluated by comparing the parameters and models that are closest to the sampled path loss when using antennas that have different patterns and polarizations in an open-source simulator. Results obtained indicate that FI model can be adapted to the majority of the environment where this model showed the lowest Root Mean Square Error (RMSE). The study of path loss models by using advanced simulator or field measurement, and studies on other rural areas from other states in Malaysia will be considered in future works. ********************************************************************************************************************** : Rangkaian 5G dijangka menggunakan jalur frekuensi Gelombang Milimeter (mmWave) dan frekuensi ini menyedia jalur lebar yang lebih lebar membolehkan kualiti servis yang lebih baik untuk para pengguna. Walau bagaimanapun, frekuensi mmWave mungkin menyebabkan kehilangan penyebaran yang tinggi disebabkan beberapa faktor seperti halangan, hujan dan atmosfera. Oleh itu, untuk membolehkan stesen pangkalan 5G berada dalam kedudukan optimum, kajian model kehilangan penyebaran dalam frekuensi mmWave untuk rangkaian 5G ini sangat penting. Kertas ini menyiasat beberapa model kehilangan penyebaran rangkaian 5G serta parameter yang paling sesuai untuk antenna polarasi-silang dalam persekitaran sel makro luar bandar di Malaysia. Model-model kehilangan penyebaran iaitu Model Kehilangan Penyebaran Berdekatan Ruang Bebas Bersama Rujukan Jarak (CI), dan Model Alpha, Beta, Gamma (ABG) atau dipanggil Model Pintasan Apungan (FI) telah dinilai dengan membandingkan beberapa parameter dan model yang paling hampir dengan kehilangan penyebaran yang sudah disampel apabila menggunakan antenna yang mempunyai corak dan polarasi yang berbeza melalui simulator sumber-terbuka. Kajian ini mendapati bahawa model FI boleh diadaptasi ke persekitaran majoriti di mana model ini menunjukan prestasi statistik punca min ralat kuasa dua (RMSE) yang terendah. Kajian model-model kehilangan penyebaran ini akan mempertimbangkan penggunaan simulator yang canggih atau pengukuran lapangan, dan juga kawasan luar bandar di negeri-negeri lain di Malaysia untuk kerja masa akan datang.
