Designers of a new radio device should always consider the need to perform appropriate self-tests. In the newly developed broadband radiocommunication recorder, a broadband receiver is one of its main components. Hence, the inclusion of a calibrator in its architecture is essential. The calibrator allows…

The increasing technological advancement of websites and web applications continually drives up the amount of data they download. Hence, the role of performance optimisation grows. The objective of the paper is to analyse the impact of optimisation of a map component’s subcomponents on its performance.…

The article describes the phishing attack phenomenon, what phishing is, its division and characteristics. Phishing, despite its simplicity, is extremely dangerous and effective - the individual phases of the attack are described along with sample phishing content. Reference was made to the methods and model…

In this paper a method for calculation of prediction propagation losses in suburban environment at 300 MHz frequency band is proposed. It is dedicated for short range (up to 1 km) communication link and takes into account location of the buildings. To estimate attenuation, proposed…

Information and communication technologies play a key role in ensuring business continuity. In most cases, companies did not envisage a scenario requiring employees to stay home and work remotely. In this situation, employees were unprepared and poorly equipped not only in terms of hardware and…

Software Defined Networking (SDN) means designing network solutions so that they can be controlled and managed dynamically and automatically using appropriate software. SDN architecture solves one of the most serious problems of today's computer networks, which are not very susceptible to changes and reconfiguration so…

The rapid increase of vehicle traffic volume in modern societies raises the need to develop innovative solutions to reduce traffic congestion and enhance traffic management efficiency. The intelligent transportation system (ITS) is an advanced technology that enables improved traffic management. However, ITS suffers from routing…

The use of a spatial selection of radio links in 5G networks is conditioned by the assessment of a power angular spectrum (PAS) of received signals. In this paper, we present a simulation procedure that allows the determination of the PAS for various environmental conditions…

In this paper, a performance of the Network Coding technique that has been adapted to 6LoWPAN-based networks is discussed. The proposed solution named NC6LoWPAN, initially tested in a real wireless sensor network, is then investigated by simulations in terms of packet buffering time and traffic…

This paper presents a study to build a prototype of an unmanned weather station operating as a LoRaWAN end device, equipped with a sensor with an autonomous power system using a battery charged by a solar cell and software created using the Arduino IDE. The…
