The operational range of conventional and license-free radio-controlled drones is limited due to line-of-sight restrictions (LoS). There exists a definitive method for operating a drone. Consequently, in order to fly the drone beyond the visual line of sight (BVLoS), it is necessary to replace the drone's original wireless communications equipment with a device that requires a licence and is connected to a cellular network. Long-Term Evolution (LTE), a terrestrial communication technique, enables a drone to establish a real-time connection with a ground station. This connection serves the goals of command and control (C&C) as well as payload delivery. Nevertheless, it is important to note that the electromagnetic environment undergoes changes as altitude increases, which can potentially complicate the process of interfacing with drones over terrestrial cellular networks. The objective of this article is to develop a prototype control system for low-altitude microdrones using LTE technology. Additionally, it seeks to assess the feasibility and effectiveness of cellular connectivity for drones operating at various altitudes. This evaluation will be conducted by examining factors like as latency, handover, and signal strength. At a certain altitude, the received signal experiences a decrease in power level by 20 dBm and a degradation in signal quality by 10 dB. The data throughput of the downlink had a fall of 70%, while the latency exhibited an increase of 94 ms. Despite meeting the basic criteria for drone cellular connection, the existing LTE network necessitates enhancements in order to expand aerial coverage, mitigate interference, and minimise network latency.

All existing communications systems require high-speed data transmission rates, as all services today demand high transmission speeds and data transmission dependability, and communications are an essential aspect of daily life. One of the most important modulation techniques used in both wired and wireless communication networks is Orthogonal Frequency Division Multiplexing (OFDM). It is a cutting-edge technology for achieving high-speed digital communication. In this work, used the Bose, Ray-Chaudhuri, Hocquenghem (BCH) code is one from methods that used for error correction. the error usually happened via noise in channel in communication system where the channel effected by different kind of noise that caused error in massage transmit by channel. this method remove the error. In several applications, and transmission over DWT-OFDM, and utilized many baseband modulation techniques, including Quadrature Phase Shift Keying (QPSK), Binary Phase Shift Keying (BPSK), Quadrature Amplitude Modulation (16QAM), and (64QAM). According to the results of the numerical simulation, 16QAM and 64QAM quarter amplitude modulation with high SNR create superior quality data at the receiver.
