Abstract

Millimeter wave (mm-Wave) communication is a promising technology for high-speed wireless communication like 5G. However, it is highly susceptible to numerous perturbations that cause significant signal loss especially rain attenuation. In this paper, we investigate the use of adaptive transmit power control as a mitigating technique for rain attenuation in mm-Wave communication. We compare the performance of this technique to that of adaptive coding and modulation using simulations of a point-to-point communication link over distances of 10m to 1000m, with transmit power varying from 100mW to 1W. Virtual experimental results show that adaptive transmit power control provides better performance than adap-tive coding and modulation in mitigating rain attenuation in mm Wave communication, This is promising for 5G technology implementation and commissioning in the tropics where rainfall is prevalent all year round.
