In Sarawak’s plantations, drones count oil palm trees and send back GPS and video data. Modern drones are smart — they use dual-band synchronization to switch between radio waves and microwaves. For your exam, remember the core contrast: Radio waves are chosen for control links because their long wavelengths diffract around obstacles. Microwaves are chosen for data and satellite links because their higher frequencies provide massive data capacity. Join the AHA moment where physics explains why drones don’t just fly — they communicate intelligently with the right waves for the right job.
