| Summary: | Millimeter wave is the key enablers for modern
wireless applications. The Utilization of millimeter wave
technology becomes a key factor in solving the problem of
bandwidth shortage. Millimeter wave leads to delivering much
higher throughput, faster data rate, and capacity. However, it is
still facing some technical challenges’. The main objective of this
paper is to identify research challenges in the mm-wave channel
and activities on modeling. A brief analysis of rain fading was
presented based on simultaneously measurement of one-minute
rain rate and its effects on a short experimental link of 38 GHz
and rain fade is observed as high as 15 dB for 300 m path at
about 125 mm/hr rain intensity. Hence rain attenuation at 0.001
% and 0.01% of outages must be considered for 38 GHz. The
statistical spatial channel mode simulation software was utilized
for an operating frequency of 38 GHz. To observe the received
power and path loss, power delay profile (PDP) was generated.
The omnidirectional and directional received power and path loss
have been estimated using environmental parameters of Kuala
Lumpur city which illustrates the theoretical performances of 5G
in Malaysia. As the receiver moves from line-of-sight (LOS) to
non-line-of-sight (NLOS) scenarios, a drop of 33.1 dB
omnidirectional power is found. |
