Multi-Connectivity in 5G and Beyond Non-Terrestrial Networks

2022

The Fifth Generation (5G) communications systems aim to serve such service classes as Ultra-Reliable Low Latency Communications (URLLC), enhanced Mobile Broadband (eMBB), and massive Machine-Type Communications (mMTC). To meet the growing requirements posed to mobile networks, satellites can be used to complement the Terrestrial Networks (TNs). To increase the efficiency of the satellite communications involved, bandwidth-efficient techniques should be used. Multi- Connectivity (MC) is one such technique. In MC, a User Equipment (UE), for example, a smartphone, can be connected to multiple Next Generation Node Bs (gNBs) simultaneously. In this paper, an adaptive MC activation scheme for thr…

Elaboration of NMT and GSM standards : from idea to market

2002

The focus of this study is on elaboration of NMT (Nordic Mobile Telephone) and GSM (Global System for Mobile communications) standards. It seeks to understand the standard-making process from a system's philosophy to market entry.The specific objectives of the study are 1) to reconstruct the original ideas of innovation, 2) to reconstruct standardization processes of NMT and GSM systems, 3) to reconstruct interplay and impact of key players during standardization process, and 4) to explain success of NMT and GSM standards. Analyzing processes of two successful mobile communication standard-making aims to reveal what were the specific Nordic standardization practices and principles, and what…

Performance Analysis of Cooperative V2V and V2I Communications Under Correlated Fading

2019

Cooperative vehicular networks will play a vital role in the coming years to implement various intelligent transportation-related applications. Both vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications will be needed to reliably disseminate information in a vehicular network. In this regard, a roadside unit (RSU) equipped with multiple antennas can improve the network capacity. While the traditional approaches assume antennas to experience independent fading, we consider a more practical uplink scenario where antennas at the RSU experience correlated fading. In particular, we evaluate the packet error probability for two renowned antenna correlation models, i.e., cons…

Robots responding to care needs? : A multitasking care robot pursued for 25 years, available products offer simple entertainment and instrumental ass…

2020

Twenty-five years ago, robotics guru Joseph Engelberger had a mission to motivate research teams all over the world to design the ‘Elderly Care Giver’, a multitasking personal robot assistant for everyday care needs in old age. In this article, we discuss how this vision of omnipotent care robots has influenced the design strategies of care robotics, the development of R&D initiatives and ethics research on use of care robots. Despite the expectations of robots revolutionizing care of older people, the role of robots in human care has remained marginal. The value of world trade in service robots, including care robots, is rather small. We argue that the implementation of robots in care is n…

Sulautettujen järjestelmien hyödyntäminen toisen asteen ammatillisessa opetuksessa

2017

Tässä Pro gradu -tutkielmassa paneudutaan sulautettujen järjestelmien hyödyntämiseen toisen asteen opetuksessa Tieto- ja tietoliikennetekniikan opetussuunnitelmassa. Tutkielmassa tutkitaan LEGO Mindstorms -, Arduino UNO - ja MatrixTSL:n ECIO-järjestelmien soveltuvuutta eri tietotekniikka-alueiden ammatilliseen opetukseen. This Master's Thesis focuses on the utilization of embedded systems in secondary education in the curriculum of Information and Communication Technology. The thesis examines the suitability of the LEGO Mindstorms, Arduino UNO and MatrixTSL ECIO systems for vocational education in various IT fields.
