Practical Feasibility

Recent advances in communication systems provide an enabling technology for aircraft connection and safety. A promising communication system that uses stratospheric platforms provides an efficient and improved communication performance and can be an efficient solution for establishing communication networks for aviation. Therefore, in this paper, a novel communication network based on stratospheric basestation (SB) is proposed to provide fifth-generation (5G) and beyond services for civil aviation aircrafts to improve global flight connectivity, control, and safety. The proposed aircraft–SB network is demonstrated, and its coverage geometry is modelled and investigated. As the 5G and beyond networks use millimeter wave frequency bands (mm-wave), the performance of different atmospheric losses including gaseous absorption, rain, and fog/cloud is analyzed to investigate the system’s practical feasibility at different 5G proposed frequencies ranging from 3.5 to 66 GHz through a flight model including three distinct stages which are takeoff/landing, climbing/descending, and cruise stages. Also, handover scenarios in the proposed aircraft–SB network are investigated and analyzed at the proposed 5G frequencies. In addition, the aircraft–SB 5G network is compared to the most recent low-Earth orbit (LEO) Internet satellites where the proposed system is expected to provide low latency, less atmospheric attenuation, longer aircraft–SB link duration, and very low handover rate.

The Future

The fifth generation (5G) of wireless communication systems is considered the key technology to enable a wide range of application scenarios and the effective spreading of the smart city concept. Vertical business use cases, specifically designed for the future 5G city, will have a strong economical and social impact. For this reason, ongoing 5G field trials have to test newly deployed technologies as well as the capability of 5G to create a new digital economy. This paper describes the 5G field trial environment that was launched in Italy at the end of 2017. The aim is to evaluate the capability of the 5G network of supporting innovative services with reference to suitably designed key performance indicators and to evaluate the opportunities offered by these services. Indeed, vertical business use cases, specifically designed for the future 5G city, with a strong economic and social impact, are under implementation and will be evaluated. In particular, the paper provides a detailed description of the deployment of an actual complete integrated 5G network. It shows how 5G is effective enabling technology for a wide range of vertical business and use cases. Indeed, its flexibility allows to satisfy completely different performance requirements of real services. Some preliminary results, obtained during the first phase, are presented for a smart mobility scenario.

5G Network

The fifth-generation (5G) network assimilates terahertz bandwidth and machine type communication (MTC) for swift and reliable data transfer and information exchange. It incorporates sophisticated cloud, Internet of Things (IoT), and other software-defined architectures for providing scalable service support. However, due to the heterogeneous integration of devices and architectures, secure infrastructures needto become mandatory. In this article, a Blockchain-based Versatile Security Framework (BVSF) is introduced to provide robust and adaptable authentication and access control in the 5G environment. The proposed framework allocates blocks for user equipment (UE) authentication and resource access control in a parallel manner. The verification of security level between resources, infrastructures, and UEs aids in extending or attenuating blockchain services. Based on the different security level assessments, the UE requests are precisely mapped or reallocated to the resources, improving the response rate and the framework adaptability.

The passive circuit elements resistor, inductor, and capacitor, which are the basic building blocks of an electronic circuit, need to be scaled down for application in fifth-generation wireless communication networks. Due to the growing demands in memory and computational capacities of integrated circuits along with high processing and transmission data speed for next-generation, microelectronics will be replaced by nanoelectronics in the future. The concept of nanoscale network on chip system is expected to play an important role in the field of communication systems for designing new devices of ultra-high speed for long and short-range communication links, power efficient computing devices, high-density memory and logic, and ultrafast interconnects. This chapter focuses on the mechanism of tailoring, patterning, and manipulating optical signals using nanometer-scale structures that may play the role of lumped nanocircuit elements at optical domain when selected properly with tremendous promise for application for fifth-generation communication systems.

The article provides the review of the specifications of the 5G, which determine the possibility of its use in qualitatively other areas compared to previous generations of mobile communication systems. Besides, areas of application of 5G, as well as examples of the potential implementation of it in them were singled out. It is shown that such a link can be used for both private and public needs, and when implemented in the defense sector – and for the state. 5G has a number of competitive advantages. Its implementation opens up new opportunities for the full development of the Internet of things, smart cities, unmanned vehicles and a number of other areas. However, along with opportunities there are certain threats, including the national security of the state. In particular, the 5G network may be attacked in order to disrupt its functioning. This can potentially lead to paralysis of part of the economy. The subject of such an attack can be both state and non-state actors. The author identified threats to national security that may arise as a result of the use of 5G. It was proposed to divide them into two categories: direct and indirect. The first one is connected with the communication itself, its software and hardware, the second - with certain areas of its application and socio-economic sphere. The untimely introduction of fifth-generation communications could exacerbate the country’s technological backwardness. The use of 5G exclusively in large cities will create a risk for the spatial development of the state.

Massive Number

The Fifth generation (5G) network is projected to support large amount of data traffic and massive number of wireless connections. Different data traffic has different Quality of Service (QoS) requirements. 5G mobile network aims to address the limitations of previous cellular standards (i.e., 2G/3G/4G) and be a prospective key enabler for future Internet of Things (IoT). 5G networks support a wide range of applications such as smart home, autonomous driving, drone operations, health and mission critical applications, Industrial IoT (IIoT), and entertainment and multimedia. Based on end users’ experience, several 5G services are categorized into immersive 5G services, intelligent 5G services, omnipresent 5G services, autonomous 5G services, and public 5G services. In this paper, we present a brief overview of 5G technical scenarios. We then provide a brief overview of accepted papers in our Special Issue on 5G mobile services and scenarios. Finally, we conclude this paper.

AbstractAt present, unmanned aerial vehicles (UAVs) have been widely used in communication systems, and the fifth-generation wireless system (5G) has further promoted the vigorous development of them. The trajectory planning of UAV is an important factor that affects the timeliness and completion of missions, especially in scenarios such as emergency communications and post-disaster rescue. In this paper, we consider an emergency communication network where a UAV aims to achieve complete coverage of potential underlaying device-to-device (D2D) users. Trajectory planning issues are grouped into clustering and supplementary phases for optimization. Aiming at trajectory length and sum throughput, two trajectory planning algorithms based on K-means are proposed, respectively. In addition, in order to balance sum throughput with trajectory length, we present a joint evaluation index. Then relying on this index, a third trajectory optimization algorithm is further proposed. Simulation results show the validity of the proposed algorithms which have advantages over the well-known benchmark scheme in terms of trajectory length and sum throughput.

A new implementation of a beam-steering transmitarray is proposed based on the tiled array architecture. Each pixel of the transmitarray is manufactured as a standalone unit which can be hard-wired for specific transmission characteristics. A set of complementary units, providing reciprocal phase-shifts, can be assembled in a prescribed spatial phase-modulation pattern to perform beam steering and beam forming in a broad spatial range. A compact circuit model of the tiled unit cell is proposed and characterized with full-wave electromagnetic simulations. Waveguide measurements of a prototype unit cell have been carried out. A design example of a tiled 10 × 10-element 1-bit beam-steering transmitarray is presented and its performance benchmarked against the conventional single-panel, i.e., unibody, counterpart. Prototypes of the tiled and single-panel C-band transmitarrays have been fabricated and tested, demonstrating their close performance, good agreement with simulations and a weak effect of fabrication tolerances. The proposed transmitarray antenna configuration has great potential for fifth-generation (5G) communication systems.
