Performance analysis of 5G path loss models for rural macrocell environment
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.

| Summary: | 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. |
