Mobile Network Performance and Technical Feasibility of LTE-Powered Unmanned Aerial Vehicle
Abstract
:1. Introduction
- -
- An LTE-powered drone prototype was constructed based on the latest hardware and software available in the market. The developed drone prototype can handle less delayed video streaming, send a real-time location, and be fully controlled using the LTE mobile network remotely. The prototype design can guide future works in this area.
- -
- A field trial measurement was conducted in a commercial LTE network and suburban environment (university campus). For measurements, the state-of-the-art techniques were used and important parameters, such as RSRP, RSRQ, data rate, latency, and handover, were measured to evaluate the system performance.
- -
- Performance of the LTE system was analyzed according to the measured parameters and large-scale pathloss channel model. To investigate the feasibility of LTE connectivity for low altitude small drones, the system performance was compared with the requirements established by 3GPP. In addition, the technical challenges of utilizing the current industrial 4G technology for providing BVLoS operations for drones were revealed. Finally, several future works and potential solutions were presented to overcome the challenges and improve the LTE connectivity performance.
- -
- The drone power consumption was studied and the main power consuming parts were revealed. The results can be used as guidance to improve energy efficiency and drone flight time for future works.
