Noncooperative 802.11 MAC Layer Fingerprinting and Tracking of Mobile Devices

open access: yesSecurity and Communication Networks, Volume 2017, Issue 1, 2017., 2017
We present two novel noncooperative MAC layer fingerprinting and tracking techniques for Wi‐Fi (802.11) enabled mobile devices. Our first technique demonstrates how a per‐bit entropy analysis of a single captured frame allows an adversary to construct a fingerprint of the transmitter that is 80.0 to 67.6 percent unique for 50 to 100 observed devices ...

Testing and Analysis of LoRa Signal Arrival Angle Based on One‐Line Array

open access: yesInternational Journal of Antennas and Propagation, Volume 2025, Issue 1, 2025.
In complex indoor environments, localization methods based on the angle of arrival (AoA) of wireless signals have better stability. Implementing LoRa signal AoA estimation mainly contains two challenges: firstly, in LoRa devices for teaching, the chip contains only a single channel and communicates in half‐duplex due to cost and power consumption ...

Multi‐Channel Wireless Communication Based on Amplitude‐Phase Reconfigurable Space‐Coding Beamforming Metasurface

open access: yesAdvanced Electronic Materials, Volume 10, Issue 8, August 2024.
This work presents an innovative amplitude‐phase reconfigurable metasurface designed to construct a robust multi‐channel wireless communication framework. Notably, the signal is modulated in the spatial domain without involving time modulation. First, it generates desired scattering beams through beamforming to establish multiple channels.
