“…Therefore, their communication range is limited by the available link budget. Specifically, their communication range is restricted to a few hundred meters in point-to-point communication on private/ad-hoc networks [34]. This range can be increased by employing repeater/relay nodes on the ground [35] or a swarm of multiple UAVs to create an ad-hoc network [36].…”

Real-time high-definition (HD) video transmission for long distances (≥1 km) between an unmanned aerial vehicle (UAV) and a ground station is a challenging problem. The existing real-time solutions are limited to relatively low-quality video streaming, whereas an HD video, which is stored in the local memory, is accessible only when the UAV returns to the ground. In this study, a real-time HD video transmission system (VTS) with a multiple-input multipleoutput (MIMO) antenna configuration and state-of-the-art coverage is proposed for security and inspection applications. The proposed VTS employs ultrathin, lightweight antennas that are suitable for seamless integration with a UAV's body without any protrusion. A 3 × 3 MIMO configuration with large antenna bandwidths (3.9% at 2.4 GHz and 6.9% at 5.2 GHz ) enables the simultaneous transmission of multiple data streams with high data rates (>30 Mbps), and a high antenna gain (~10 dBi) allows a relatively long communication range (>3 km). In field experiments, the UAV module (comprising thin conformal antennas, embedded electronics, an RF transceiver, and an HD camera) is attached to a commercial drone DJI Matrice 600 Pro. The HD video's reception performance is investigated for operation in two frequency bands (2.4 and 5.2 GHz) for both horizontal and vertical antenna orientations. The maximum and average data rates for various distances are reported. Based on the conducted field experiments, it is found that the proposed VTS is capable of transmitting real-time HD video up to a 3.56km distance with a receiver sensitivity of −76 dBm. The maximum achieved data rates at a 500-m distance are ~10 and ~43 Mbps for operation in the 2.4-and 5.2-GHz frequency bands, respectively.
