In conventional mobile communications systems, network services are designed to serve a huge amount of subscribers simultaneously, which is normally called a network-centric design approach. In comparison, this paper aims to investigate the user-centric design approach, which refers to sys-tems that are designed to be user-defined, user-configurable and user-controllable. The user-centric approach allows for dedicated network services to be provided at the granularity of the user. A novel User-Centric Network (UCN) architecture is proposed in this work, which includes key design principles, corresponding network elements as well as procedures. It is envisioned that UCN is distributed in nature by leveraging enabling technologies like Distributed Ledger Technology (DLT) and Distributed Hash Table (DHT). In this way, UCN not only provides extreme customization by offering fine-grained services, but also enables autonomous and trusted data control and privacy protection. A simulation platform is developed to verify the feasibility of the architecture, and to preliminarily evaluate its performance by numerical results in terms of hop count, bandwidth consumption, latency, success ratio and scalability.

Use of high frequency millimeter wave (mmWave) bands as the communication solution for a variety of new verticals has been of interest over the past several years. While the inherent range limitation of mmWave bands make them the perfect candidate for building localized private indoor networks, transmissions at these high frequencies are also susceptible to absorption losses. Hence, despite the availability of large bandwidths, there has been a relatively slow uptake of these bands for licensed services. To address this, we explore the feasibility of mmWave by experimentally validating the performance of closed-loop control applications with indoor mobility requirements over hybrid combinations of wired and 5G networks. Our experiments, executed over an indoor non-standalone (NSA) 5G deployment at 28GHz, revealed comparable performance of industrial robotics systems when communicating over 5G mmWave or Ethernet.

Misfocus or beam squint, is a fundamental prob-lem for reconfigurable intelligent surface (RIS)-assisted beam-forming. In this work, we investigate two methods for misfocus-reduction based on the stationary phase method (SPM) and the semi-definite relaxation (SDR), respectively. The proposed algorithms can provide a misfocus robust phase shift configuration. In the SPM-based algorithm, a closed-form expression is given, which reduces the computational complexity and has high efficiency when the RIS elements number is large. We use the circuit model to characterize the frequency selectivity of RIS elements. We investigate our methods under several critical factors: the number of RIS elements, the beamfoming bandwidth and the impact of the frequency selectivity of RIS itself.

As the shipping sector has been one of the major impact factors on economic growth over the past decades, its digitalization is expected to make unprecedented improvements in the safety and reliability of ship control, thereby ultimately enabling the autonomous operations of ships. The automated control of ships will not only mitigate the risks of human mistakes but will also improve the efficiency of operations by preventing unexpected delays while being environmentally sustainable. With the advent of the Internet of Ships (IoS) sector, well-known and mature concepts of the Internet of Things (IoT) are being applied to ships and ports, thereby making them more and more equipped with sensing and communication capabilities that set the ground for improved situational awareness and better decision-making. However, there are many challenges that need to be thoroughly studied, such as the communication between barges, ports, and services, as increased network latency and limitations on the bandwidth imposed by satellite communications could introduce significant risks for accident occurrence, ultimately affecting the overall automated operation/teleoperation of barges. In this paper, we present one of the first attempts to test the potential of 5G systems for automating barge operations, starting from teleoperation as an enabler of automation, thereby creating and validating a cellular-based automated barge control system in a real-life environment. In this system, the barge is sailing in a busy port area such as one of the Port of Antwerp Bruges, while being connected to the 5G network. We assess the quality of the 5G communication system and present and discuss our initial results on the enhancements that 5G could bring to teleoperation and automation of the barge control.

As future wireless communication systems aim to achieve increased data rates, system capacity, and reduced latency and power consumption, they have shifted towards higher frequency bands such as Millimeter Wave (mmWave) and Terahertz spectrums. However, these spectrums pose challenges in terms of the quality of the communication link, including large path-loss and limited coverage, as well as difficulties in system and antenna design. Reconfigurable Intelligent Surfaces (RISs) have recently been proposed as a promising low-cost and low-power consumption solution to enhance the performance of wireless communication systems. However, beamforming with RISs can be difficult, especially in the presence of beam widening requirements, which aim to produce wide beams for cell or sector-wide broadcasting, among other applications. In this paper, a new approach for beam widening in RIS-assisted communications using genetic algorithms is proposed. The focus is on using phase-only tapering to achieve wide beams while minimizing sidelobes (SSL) and beam ripple. To address this problem, two cost functions are developed and optimized using genetic algorithms. The optimization results in a codebook of 1-blt phase patterns with varying beamwidths, making it possible to widen the beams without requiring extra controllers or specific element designs. The proposed approach is evaluated through simulation results, which demonstrate its effectiveness in achieving wide beams while maintaining a low level of sidelobes and beam ripple.

During the latest years, LoRaWAN has emerged as a valid alternative to cellular technologies for Internet of Things applications, thanks to its long-range capabilities and high energy efficiency at the expense of a very limited bit rate. To support highly demanding applications, in 2017, Semtech released the first LoRa module working at 2.4 GHz, but the LoRaWAN protocol has not been updated to support such a version, despite the wider frequency channels available in this frequency portion. In this paper, we perform a quantitative analysis on the exploitation of this frequency spectrum in the currently released LoRaWAN version, comparing it with the standard EU868 MHz version. By means of extensive ad-hoc network simulations obtained with the open-source LoRaWANSim, we point out the main advantages of the 2.4 GHz version (e.g., higher throughput) and disadvantages (e.g., coverage issues), for both transmission directions, and as a function of different parameters, such as the number of devices, gateways, area size, and payload. Numerical results show that LoRaWAN at 2.4 GHz is a viable solution for scenarios characterized by a high density of nodes in a limited area, whereas LoRaWAN in the EU868 MHz spectrum remains the preferred choice when considering wide environments.

The advent of 5G New Radio (NR) technology has revolutionized the landscape of wireless communication, offering various enhancements such as elevated system capacity, improved spectrum efficiency, and higher data transmission rates. To achieve these benefits, 5G has implemented the Ultra-Dense Network (UDN) architecture, characterized by the deployment of numerous small general Node B (gNB) units. While this approach boosts system capacity and frequency reuse, it also raises concerns such as increased signal interference, longer handover times, and higher handover failure rates. To address these challenges, the critical factor of Time to Trigger (TTT) in handover management must be accurately determined. Furthermore, the density of gNBs has a significant impact on handover performance. This study provides a comprehensive analysis of 5G handover management. Through the development and utilization of a downlink system-level simulator, the effects of various TTT values and gNB densities on 5G handover were evaluated, taking into consideration the movement of Traffic Users (TUs) with varying velocities. Simulation results showed that the handover performance can be optimized by adjusting the TTT under different gNB densities, providing valuable insights into the proper selection of TTT, UDN, and TU velocity to enhance 5G handover performance.

Using drones opens up possibilities for many novel services to be deployed in local networks. From the network point of view, having a mobile User Equipment (UE) in the air poses additional source of interference towards neighbouring local networks. This paper develops a calculation model for the interference and verifies the model with a field measurement campaign.

Given the large amount of data usage and diverse business models in the current market, 5G and B5G networks are forecasted to manage and support a variety of new business solutions with respect to high-performance needs, while also allowing existing services to be enhanced and optimized. One effective way to accomplish this is by fully utilizing the network's openness and programmability in terms of both business and technical level coordination. A cornerstone to the above mentioned premise is the implementation of the Network Exposure Function (NEF) interfaces that are required in order for NEF to expose the standardized APIs. In this context, the paper presents the concept of network exposure via a simulation tool that enables application developers to experiment with the northbound APIs under a simulated and configurable environment. Moreover, the required software that interacts with the exposed APIs, namely the Network Application, is introduced and validated on top of the Internet of Things (IoT) and Machine to Machine (M2M) use case, which falls under the scope of the Factory of the Future and Industry 4.0 concept.

Deep learning is applied to implement base station switching in physical layer using imaging data for 60 GHz millimeter-wave communications where the received signal is susceptible to blockage. In particular, a predictive model is trained from video frames and received signal data. Accordingly, the video frames are used to predict received power two seconds ahead using three-dimensional convolutional neural networks and long short-term memories, followed by proactive switching decisions. The model can predict the future received power with root-mean-square errors under 2 dB. The proposed prediction-based proactive switching method surpasses the reactive approach in terms of connected duration, maintaining a stable connection in various blockage moving trajectories.

The proposed prediction-based proactive switching method surpasses the reactive approach in terms of connected duration, maintaining a stable connection in various blockage moving trajectories.","PeriodicalId":65870,"journal":{"name":"公共管理高层论坛","volume":"5 1","pages":"72-77"},"PeriodicalIF":0.0,"publicationDate":"2023-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89828650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
