What is mmwave frequency band in Malaysia that approved by MCM? 


Best insight from top research papers

The mmWave frequency band approved by the Malaysian Communications and Multimedia Commission (MCMC) is 26 GHz, which falls under the Ka Band category . This frequency is widely used for local multipoint distribution service deployment in tropical regions like Malaysia . Studies have shown that at 26 GHz, rain attenuation can impact data link reliability during rainfall, making it crucial to have accurate prediction models for terrestrial links operating at this frequency in tropical climates . The use of ITU-R model, revised Moupfouma model, revised Silva Mello model, Lin model, and the newly introduced Abdulrahman model have been explored to predict rain attenuation at 26 GHz in Malaysian tropical regions . The research emphasizes the importance of selecting the most suitable prediction model to enhance the performance of 5G links in such environments .
