Evidence shows that information and communications technologies (ICT), especially mobile telecommunications services, can lead to sustained economic growth and human development. Mobile technologies are increasingly used as a transformational tool to foster economic growth, accelerate knowledge transfer, develop local capacities, raise productivity, and alleviate poverty in a variety of sectors. In that respect, in the last decade, ICT development has become a key strategic area for policy engagement in emerging economies. To support policy-makers and marketing practitioners in designing optimal telecommunications sector development strategies, an increasing research focus is now being placed on the impediments to implementing ICT solutions in the developing world. As a contribution to this field of research, this study aims at (i) identifying the economic and socio-cultural determinants affecting the capacity of developing countries to adopt new technologies and innovations, and at (ii) defining relevant policy principles likely to foster the diffusion of ICT solutions in emerging economies that are characterized by strong income inequality and uncertainty avoidance
Mishra, Debashisha. "Exploiting the synergies of unmanned aerial vehicles (UAVs) and 5G network". Electronic Thesis or Diss., Université de Lorraine, 2023. http://www.theses.fr/2023LORR0058.
As an expanding subject of aerial robotics, Unmanned Aerial Vehicles (UAVs) have received substantial research attention within the wireless networking research community. As soon as national legislations enable UAVs to fly autonomously, we will witness swarms of UAV filling the skies of our smart cities to complete diverse missions: package delivery, infrastructure monitoring, event videography, surveillance, tracking, etc. Fifth generation (5G) and beyond cellular networks can improve UAV communications in a variety of ways and thus benefit the UAV ecosystem. There is a wide variety of wireless applications and use cases that can benefit from the capabilities of these smart devices, including the UAV's inherent characteristics of agile mobility in three-dimensional space, autonomous operation, and intelligent placement. The broad goal of this thesis is to provide a comprehensive analysis of the synergies that may be realized when combining 5G and beyond cellular networks with UAV technology. This thesis presents four types of UAV and cellular ecosystem integration models. "UAV-assisted cellular paradigm" refers to communication scenarios in which UAVs are used as flying (or aerial) base stations or as relays to augment current terrestrial cellular connectivity or to mitigate disaster situations. The "cellular-assisted UAV paradigm" foresees the integration of UAVs into the current cellular network as a new aerial user (flying UE) to serve a wide variety of applications and use cases. The "UAV-to-UAV paradigm" stresses the collective strength of a fleet of UAVs as a swarm and communication amongst UAVs inside the swarm. The "hybrid non-terrestrial paradigm" encompasses satellite and aerial networks, therefore examining the whole spectrum of communication links from the ground to the air to the space in the form of an integrated space-air-ground communication network. Initially, this thesis focuses on aerial base stations, which have gained great academic attention in order to provide flexible, on-demand communication services to ground users. On this occasion, we build and construct a proof-of-concept prototype platform that delineates the design components required to implement such platforms in the real world, and we then explain the necessity for optimal placement of aerial base stations for increasing communication services. To support a heterogeneous class of 5G services from various vertical industries (referred to as tenants of 5G network operators), we propose a slicing-aware aerial base station framework in which ground users with differentiated traffic requirements in terms of data rate, latency, and massive deployment are supported through intelligent resource provisioning. Second, we describe aerial users who are supported by current cellular infrastructure and examine difficulties such as coexistence of aerial users and ground users, handovers, and communication-aware trajectory optimization. The use of a swarm of UAVs is considerably more cost-effective as compared to a single UAV conducting a mission when considering realistic mission goals. A swarm of UAVs opens up new opportunities for new services and applications since the UAVs may independently coordinate their operations and work together to complete a given task. Due to the spatio-temporal dynamics of swarm topology, dependable network development with seamless communication amongst UAVs is essential for any operation to be successful. As part of this thesis, we offer centralized and decentralized network models for UAV-to-UAV (U2U) communication inside swarm and conduct a full investigation of sidelink-assisted U2U communication with performance assessment
