| Summary: | In recent years, the growth of mobile handset technology use has caused network
congestion due to the increasing demand for multimedia services. While
communication systems are moving towards a 5G network in response, the frequencies
of the 5G network, which are 26 GHz and 28 GHz, as suggested by the Malaysian
Communications and Multimedia Commission, are susceptible to signal loss due to
atmospheric conditions, especially in heavy rain regions, such as Malaysia. Regarding
service quality, yearly and monthly rain attenuation in Malaysia must be considered
by network designers to ensure constant availability of the 5G link. To this aim, rain
attenuation for the 5G network in Peninsular Malaysia is investigated. Rainfall data
from the Universiti Tun Hussein Onn Malaysia (UTHM) is collected using a tipping
bucket rain gauge, while rainfall data from the Universiti Teknologi Malaysia, Kuala
Lumpur (UTM-KL) is collected using an RD-69 disdrometer. Both data sets serve as
important inputs for the Synthetic Storm Technique and ITU-R prediction models for
rain attenuation in Malaysia. Monthly rain attenuation statistics are also derived from
the conversion of one-hour to one-minute rainfall rate statistics using the ITU-R P.8377
method.
The

that

comparable
and
can
be used for the prediction of rain attenuation for 5G communication systems in
this heavy rainfall area. Detailed analysis of the results also suggests that a 0.2 km path
length for the microwave link will experience very low attenuation which is less than
15 dB and hence require a smaller fade margin value. Additionally, seasonal monsoon
analysis reveals that the inter-monsoon and northeast monsoon seasons record the
highest rain attenuation at UTHM and UTM-KL, respectively. The rain attenuation
contour map for Peninsular Malaysia at 0.01 % time of exceedance is developed from
the 75 rain gauge network stations provided by the Malaysia Meteorological
Department. The optimum rain fade margins of 13 dB for 26 GHz and 15 dB for 28
GHz are proposed for a 5G communication system in Peninsular Malaysia at a path
length of 0.2 km with horizontal polarization. |
