A Review on Autonomous Relay For Millimeter Wave Wireless Communications
Greeshma Sosa Thomas, C. Sarath Chandran · IOP Conference Series Materials Science and Engineering · 2018
Millimeter-wave wireless communication is an uprising technology. Millimeter-wave has large bandwidth and short wavelength. Eventhough it is advantageous, it gets easily blocked by obstacles. As a result, effective communication does not take place. Relays are used widely to solve this problem. Unmanned Autonomous Vehicles (UAV), such as drones, allows the mobile relays in real applications. It is difficult for relay to find its position quickly and accurately. Here, a method AutoRelay specialized for mmwave communication have been reviewed. In AutoRelay, the link qualities of mmwave beams are sampled while moving. Based on real-time sampling, UAV adjusts its path to reach the optimal location by using compressive sensing theory which increases accuracy and saves time.
