“…This is mainly due to the insufficient spatial resolution of WiFi signals, which leads to the mixing of signals from multiple users. Currently, there are two potential solutions: one is to improve the spatial resolution of the system by using more advanced antenna technology [39]; the other is to limit the direction of signal transmission in order to better spatially discriminate the signals of different users.…”

With the proliferation of WiFi devices, WiFi-based identification technology has garnered attention in the security domain and has demonstrated initial success. Nonetheless, when untrained illegitimate users appear, the classifier tends to categorize them as if they were trained users. In response to this issue, researchers have proposed identity legitimacy authentication systems to identify illicit users, albeit only applicable to individual users. In this article, we propose a multi-user legitimacy authentication system based on WiFi, termed Multi-WiIR. Leveraging WiFi signals, the system captures users’ walking patterns to ascertain their legitimacy. The core concept entails training a multi-branch deep neural network, designated WiIR-Net, for feature extraction of individual users. Binary classifiers are then applied to each user, and legitimacy is established by comparing the model’s output to predefined thresholds, thus facilitating multi-user legitimacy authentication. Moreover, the study experimentally investigated the impact of the number of legitimate individuals on accuracy rates. The results demonstrated that The Multi-WiIR system showed commendable performance with low latency, being capable of conducting legitimacy recognition in scenarios involving up to four users, with an accuracy rate reaching 85.11%.

“…New opportunities in cellular positioning like the massive multiple-input-multiple-output (MIMO) also introduce more degree of freedom (DoF) for location and sensing applications [25], [26], and the expression of CRLB has also been derived in [27], [28]. A general-purpose antenna extension solution has been proposed in [29], which can provide extended radio chains of commodity devices for both communication and localization [30]. Besides the design of novel estimation methods as in [6], [31], researches in [32]- [34] have successively proposed a series of deployment strategies for anchor nodes for accurate location estimation in cellular internet-of-things (IoT) networks.…”

“…High resolution RF sensing entails special hardware to exploit ultra-wideband (GHz) transceivers, multiple antennas, and/or specialized signal modulation (e.g., FMCW) [4,95,126,135]. For example, mmWrite [95] proposes a handwriting recognition system based on accurate hand tracking with using millimeter wave hardware.…”

“…By reusing the wireless signal that was conventionally used for communication purpose, a variety of applications on wireless sensing have been proposed. For example, with analyzing the indoor propagation of Wi-Fi signal, researchers have achieved diverse applications such as indoor localization [133][134][135][136][137], motion recognition [42,53,67,148,152], heartbeat/respiratory monitoring [108,124], etc. The wire-less sensing research that evolves out of basic communication theories will make future social life more intelligent, efficient and convenient.…”

First, I would like to express my grateful thanks and sincere respect to my supervisor, Dr. Mo Li. I had no concept of research when I enrolled in this Ph.D career four years ago. During these years, Dr. Mo Li helped me develop classic research taste, rigorous research attitude, and standard research logic. I learned a lot from him, not only about research, but also about the bravery when I have to face difficulties, the resilience when I have to take paper rejections, and the optimism when I have to accept failures. Ph.D study is not easy, fortunately, I work with the best supervisor.Second, I would like to thank my mother and my father. They spent all their energy during the past thirty years protecting a warm family where I can grow up, get mature and learn responsibility. They act physical examples to explain me the meaning of diligence, integrity and gratitude, which set me up from the inside so that I can approach to complete the Ph.D study. In particular, I want to thank my mother. She does not talk too much, but the way she works always inspires me to keep moving forward.
