Could Your Mobile Broadband Internet Provider Threaten Your Digital Privacy?

Users privacy is more and more relevant in today digital world. In this paper, we study how mobile network operators (MNOs) practices can lead to loss of privacy for mobile phone subscribers. This article focuses on the mobile phone service providers' implication in privacy violation. Network attacks from other agents, such as cyber-criminals, are not covered in this work. We review the impact of the location tracking improvement from 2G to 5G networks on police investigations and users' privacy rights. We also study the role of MNOs in users' sensitive data monetization and the legality behind this practice. There are few existing publications aiming to enhance mobile phone users' privacy protection against mobile broadband internet providers. We have tried to list all of them in this article

5G Vs Wi-Fi Indoor Positioning: A Comparative Study

Sensing location information in indoor scenes requires a high accuracy and is a challenging task, mainly because of multipath and NLoS (non-line-of-sight) propagation. GNSS signals cannot penetrate well in indoor environment. Satellite-based navigation and positioning systems cannot therefore be used for indoor positioning.. Other technologies have been suggested for indoor usage, among them, Wi-Fi (802.11) and 5G NR (New Radio). The primary aim of this study is to discuss the advantages and drawbacks of 5G and Wi-Fi positioning techniques for indoor localization
