Cell Movement of Rain Impact in Satellite and Mobile Communication Based on Tropical Maritime

摘要

Satellite and mobile communication is one of answers to bandwidth limitation of a communication network. However, satellite signals get distrupted in rainy conditions. Power link budget needs to be adjusted to a certain level for good communication. This research is conducted to obtain the proper transmit power and digital modulation for use during rainy conditions. We have measured rain rates in Mataram for three years to get rain attenuations which are then used in simulations. Cross-correlation method is applied to determine movement cells. From simulation results, it is found that the average rain attenuation is 20.67 dm/km with a maximum rain rate of 197 mm/h. This rain rate value is much higher than the standardized rain rate of 47.1 mm/h in V-band. Therefore communication design for 5G system, need to consider of the rain attenuation especially for tropical climates.
