Abstract:

ABSTRACTThe present work proposes a methodology for evaluating building Wi-Fi networks using a spectrum analyzer alongside Wi-Fi network analysis tools. The Agilent CSA Spectrum Analyzer, model N1996A-506, and the tools ManageEngine OpManager and PRTG Professional Wi-Fi Analyzer will be used to measure the Wi-Fi signal of an academic building. The collected Received Signal Strength Indicator (RSSI) data will be imported and modeled in Python code to generate heatmaps that visually represent the quality of the Wi-Fi network coverage. The results obtained from the tools will be compared with tho

Abstract Operating in probably the most crowded radio frequency bandwidth, the 2.4 GHz Wi-Fi is still common in the majority of living environments. Besides having to face problems regarding co-channel and adjacent channel influence, Wi-Fi often coexists with other radio technologies operating in this bandwidth which makes it ideal for interference testing. In this article authors propose the use of freely available mobile applications to measure Wi-Fi signal spreading within a residential home as well as to quantify Wi-Fi performance in the presence of some commonly available interferers.

Abstract:

Abstract The goal of the study is to determine and compare the attenuation of electromagnetic waves at 2.4 - 2.5 GHz frequency between plain single jersey and 1x1 rib knitted fabric. For knitting the samples, three different types of metal-contained yarns, their combinations, and cotton yarn were used. Two horn antennas and a network analyzer were used to characterize the transmission of the samples in the frequency range of 2.4-2.5 GHz. Obtained results show, that in mentioned frequency range single jersey knitted samples attenuate better than the rib samples.

Abstract:

In the wake of the COVID-19 pandemic, there has been a significant digital transformation. The widespread use of wireless communication in IoT has posed security challenges due to its vulnerability to cybercrime. The Indonesian National Police’s Directorate of Cyber Crime is expected to play a preventive role in supervising these attacks, despite lacking a specific cyber-attack prevention function. An Intrusion Detection System (IDS), employing artificial intelligence, can differentiate between cyber-attacks and non-attacks. This study focuses on developing a machine learning-based policing mo

Abstract:

Wireless communications play a crucial role in human lives. The introduction of cellular network systems, broadband internet services and public Wi-Fi services increase the connectivity between people exponentially. These wireless networks require antenna structures to propagate carrier waves through space and these waves are located within the Radiofrequency (RF) region in the electromagnetic spectrum. The effects of these RF waves on people, especially children, and pregnant women cannot be neglected. According to the researchers, there are some adverse health issues related to thermal and n
