Evaluation of Unmanned Aerial Vehicle (UAV) control range system using Lora-based communication system using path loss

This research aims to evaluate the communication system between the ground control system and the Unmanned Aerial Vehicle (UAV) using the Lora communication system based on its Path Loss data. Lora itself is a 433 MHz-based communication system used for very long-distance communication. As we know, today UAV market used a 2.4 GHz-based communication system because it is cheaper than using 433MHz. But, although it is cheaper than 433MHz, a lot of devices used the same frequency like WiFi systems and other wireless electrical component. That condition creates a lot of signal interference so communication between the ground control system and the UAV becomes shorter. 433MHz is not a new technology for a communication system, this frequency is usually used for radio news and long-range data logging. It is rarely used 433 MHz frequency for transmitting a big package of data because 433Mhz frequency has a slow data transfer rate but has a long data transfer distance. From testing, we got an improvement of control range more than twice with Lo-Ra 433 MHz compared to the 2.4 GHz module
