“…The testbed has over 30 grid nodes, which consist of an Ettus USRP X310 or N210 SDR with a dedicated host computer connected via Ethernet. We have used Wireless Insite, ray-tracing software developed by Remcom, Inc. [30], to model wireless channel conditions that are inherently difficult to study such as UAV Air-to-Ground data links [19,31]. The use of Wireless Insite with our testbed enables a realistic highly scalable evaluation of devices under scenarios with high mobility, unique height profiles, urban and outdoor settings, and carrier frequencies up to 100 GHz.…”

“…The UAV travels at a rate of 0.5 m/s with an altitude varying between 6 and 7 m over a circular trajectory with a radius of 7 m. The ground nodes use antennas with heights of 2 m and travel randomly within a bounded area of approximately 50 by 50 m at a rate of 0.25 m/s. The jammer is located approximately 32 m from the centre of the trajectory and also has an antenna height of 2 m. A model of the selected area is developed for Wireless Insite in [31]. The scenario features are shown in Figure 11, with concrete buildings in tan colour, grass parks in green, and concrete walkways in grey.…”

Cyber-physical systems (CPS) integrate control, sensing, and processing into interconnected physical components to support applications within transportation, energy, healthcare, environment, and various other areas. Secure and reliable wireless communication between devices is necessary to enable the widespread adoption of these emerging technologies. Cyber-physical systems devices must be protected against active threats, such as Radio Frequency (RF) Jammers, which intentionally disrupt communication links. Jamming detection and mitigation techniques must be evaluated extensively to validate algorithms prior to full implementation. Challenges related to obtaining zoning permits, Federal Aviation Administration (FAA) pilot certification for Unmanned Aerial Vehicles (UAVs), and Federal Communications Commission (FCC) licencing lead to evaluation limited to simulation-based or simplistic, non-representative hardware experimentation. A site-specific ray-tracing emulation framework is presented to provide a realistic evaluation of communication devices under RF jamming attacks in complex scenarios involving mobility, vehicular, and UAV systems. System architecture and capabilities are provided for the devices under test, real-world jamming adversaries, channel modelling, and channel emulation. Case studies are provided to demonstrate the use of the framework for different applications and jamming threats. The experimental results illustrate the benefit of the ray-tracing emulation system for conducting complex wireless communication studies under the presence of RF jamming. K E Y W O R D Scyber-physical systems, hardware-in-the-loop stimulation, telecommunication security | INTRODUCTIONWith the emergence of new wireless technologies in our everyday lives, such as in Cyber-Physical Systems (CPS), Vehicular, Unmanned Aerial Vehicle (UAV) communications, and the Internet of Things (IoT), protecting devices against external threats is essential for society to thrive in the future. Cyber-Physical Systems in particular has a high dependence on communication systems for data and control, leading to vulnerabilities to attacks [1]. Radio frequency (RF) jammers disrupt the wireless RF medium by transmitting signals with the malicious intent to interfere with legitimate communication systems. In critical communication systems, for instance, autonomous vehicles, medical device readings, and mobile access points for disaster relief, the consequences can be catastrophic.Types of RF jammers include constant, random, intermittent, reactive, and intelligent [2]. The constant jammer is straightforward in operation, sending a jamming signal at a centre frequency with a given bandwidth. The continuous nature of the threat results in simple detection and inefficient energy usage; therefore, more complex jammers are implemented. Random jammers trigger a jamming event with a set probability; similarly, intermittent jammers operate in setThis is an open access article under the terms of the Creative Commons Attribution License, which permi...

“…In [22], the performance of an IEEE 802.11a compatible OFDM for UAV downlink with large Doppler shift and inter-carrier interference (ICI) is analyzed. Similarly, the effect of ICI and inter-symbol interference from multi-path propagation are analyzed in [23] for OFDM based UAV data link communication in urban environment. The fast Fourier transform (FFT) size of OFDM is increased to improve system performance with synchronization requirements.…”

The use of Aerial Base Stations (ABSs) has received a great deal of attention in academia and industry as a means to support the cellular communication traffic growth. In this article, we focus on obtaining the optimal altitude of an ABS using two criteria -maximum cell coverage area and minimum Symbol Error Rate (SER). Our study is done by using a probabilistic airto-ground channel model, developed for low altitude aerial platforms via simulations on a commercial ray tracing software, for different scenarios like Urban High Rise, Urban, and Suburban. The probability distributions of the received power of the ground users and of the power delay profile at optimal ABS altitude are provided as a function of the size of the cell area. For the SER analysis, we present a system model based on Generalized Frequency Division Multiplexing (GFDM), in a time-frequency grid that is compatible with Long Term Evolution, by implementing parameters for low latency communication at the physical layer. The impact of "Better than Nyquist" pulses on the GFDM system is evaluated in terms of SER performance. From the presented results, a significant improvement is demonstrated compared to the traditional Nyquist pulses.

The increased utilization of unmanned aerial vehicles (UAVs) in the commercial market and military on account of their agility, nonpiloted and easy manoeuvering leads their applications in the telecommunication sector as well. It is expected that UAVs will play a vital role in 5G and Beyond 5G (B5G) networks as flying base stations (BSs) and/or relays. Recently, they are also proposed to assist the existing terrestrial communication infrastructure in forthcoming 5G/B5G to provide improved wireless network coverage particularly to the areas difficult to reach, the scenarios demanding high data rate and low latency on emergency needs, transceiving sensors data from field to the ground servers and providing wireless network coverage in a disaster where existing terrestrial communication infrastructure gets partially/severely damaged. However, it is of an utmost challenge to model the radio propagation channel from a UAV (low altitude platforms) to existing terrestrial BSs, the receiver on ground and with other flying UAVs in a network. This paper provides a survey of both measurement and simulation based radio propagation channel modelling investigations for a low altitude UAV enabled wireless network. Furthermore, the potential open research gaps and use cases are highlighted which will be key to define the role of UAVs in future wireless networks for various applications.
