ΝΒ-ΙοΤ Technology Benefits in Educational Institutes

Apostolos Gkamas

University Ecclesiastical Academy of Vella, Greece

The Internet of Things (IoT) is the extending of Internet connectivity to physical devices and common objects. Narrow Band-Internet of Things (NB-IoT) is a component of the 5G network infrastructure that focuses on providing connec-tivity to IoT devices. NB-IoT is a standards-based Low Power Wide Area Net-work (LPWAN) technology that allows a wide range of new IoT devices and services to be developed. This paper presents the benefits of using NB-IoT tech-nology in Educational Institutes. The aim of this paper is to answer the following question: "How has the emergence of NB-IoT technology affected the Education Process and an Educational Institute Operation?". The paper begins with a brief overview of IoT networks and NB-IoT technology, followed by a discussion of the potential benefits of NB-IoT technology in Educational Institutions. In addi-tion, we examine the impact of NB-IoT technology on the educational process and the functioning of an Educational Institute. Moreover, we compare NB-IoT against other similar technologies like LoRa in the context of Educational Institute Operation.

Proposal for a Deployment of a Non-Standalone 5G Mobile Network Architecture for Developing Countries: Case of Senegal

Latyr Ndiaye, Samba Diouf, Kéba Gueye, Samuel Ouya

UCAD/ESP, Senegal

Mobile networks have evolved a lot in recent years, moving from 2G to 5G. This transition is marked in Africa by a delay compared to the West, especially for 4G. Today, developed countries have deployed 5G either in standalone mode or in non-standalone mode. Developing African countries should not be the last to benefit from the advantages that 5G will offer in terms of bandwidth, very high speed but also in short latency.

The huge costs of deploying the latest generation networks so much advocated by the players have pushed some Africans to avoid investments in the field. Our objective is to show developing African countries that today it is possible to deploy a reliable and low cost next generation mobile network. Based on new infrastructures, it is possible to emulate the entire telecom infrastructure with IT. We propose a deployment of a last generation 5G network in non-autonomous mode, to allow African countries that have just deployed 4G not long ago not to make a loss-making investment. We will use the power of SDR to implement all the radio infrastructure and the network part. SDN will enable automation of infrastructure management tasks for a large-scale deployment.

Automatic Code-Switched Lecture Annotation

Amjad Mohamed, Nada Nasser, Nada Sharaf

The German University in Cairo, Egypt

Advanced technology, like Automatic Speech Recognition, has various usages in our everyday lives. By taking advantage of this advanced technology, we were able to help make easier the learning process for deaf and hard-of-hearing students. Our lecture annotation tool facilitates the learning environment to these students by proving post-lecture annotations on lecture slides. The system does this by utilising the lecture slides, audio recording of the lecture and Automatic Speech Recognition API services. The system goes through two phases, the transcription phase and the slide matching phase. After recording the lecturer, the audio file is input to the transcription module and the transcription module transcribes the audio file and outputs text. The main challenge here was that lecturers use code-mixed language (English/Arabic). So the transcription module transcribes bilingual audio simultaneously by chunking up the audio file. Afterwards, the text and the lecture slides are input to the slide-matching module and the slide-matching module outputs a PDF file with the text aligned on the PDF slides accordingly. This PDF lecture file can later be viewed by students to help them study and understand the lecture.

Moodle platform and Online Renewable Energy Laboratory at Faculty of Electrical Engineering

Hen Friman, Netser Matsliah

Faculty of Engineering. H.I.T - Holon Institute of Technology, Holon, Israel

Due to the rising need for professionals and academics with a background and understanding in the Renewable Energy field, the Holon Institute of Technology ("HIT") developed a new program at the Faculty of Electrical Engineering. The Institute offers its students a well-equipped laboratory, containing state-of-the-art equipment in various fields such as photovoltaic energy systems, smart grid telecommunications, and information security platforms, wind, and water energy work stations, and power electronics equipment. The Renewable Energy Laboratory is operating under a new experimental teaching method and presents itself as the "next generation" lab. The Lab is "paperless", which means that all the experiments' notes, as well as the theoretical background, are computerized. The notes and experiments are all integrated into a "Moodle" platform. Each student fills an anonymous computerized feedback questionnaire at the end of all experiments. In this questionnaire, they are asked about this new method of the computerized learning experience. In this paper, a summary of the results of the pilot conducted last four years is presented.

Work-in-Progress: Construction Safety Using Visual Technological Support

Accidents occur on construction sites that are complex and unique environments, making these difficult to control and monitor. Above all it is not acceptable that in the XXI century anyone dies due to improper working conditions. A European funded project by Erasmus+ Programme intends to alleviate this situation. The idea is that digital tools allow the creation of simulations of construction scenarios allowing the identification and prevention of risks for workers, technicians and engineers. The project develops tools with IR (Immersive Reality) and AR (Augmented Reality) procedures based on BIM modelling capacities to prevent accidents through training. Project also aims at offering training sessions online on an online platform to grant learners and trainees access to interactive material and resources. These tools range from applications to be used on smartphones to virtual reality contexts depending on the needs of training.
