On September 24, 2021, at the ACM 2021 UbiComp conference held online, Professor Zhang Daqing's paper "Exploring LoRa for Long-Range Through-Wall Sensing (IMWUT Vol. 4 Issue 3 Sept. 2020) won the Outstanding Paper Award of the Conference (Distinguished Paper Award).

ACM UbiComp is a top international conference in the field of ubiquitous computing and is listed as a Class A conference by CCF (Chinese Computer Society). The Outstanding Paper Award of the conference was reviewed by the jury and selected from 174 UbiComp articles, with a grant rate of only 3.5% of the accepted articles. The jury commented that the paper "groundbreaking new perspective on the use of LoRa for wireless perception, and the use of LoRa partition walls to sense human breathing, etc., make this research deeply enlightening and practical. The author has designed a series of ingenious experiments to produce exemplary experimental verification results."

This paper is the first to apply low-power, long-distance communication LoRa technology to long-distance non-contact sensing. Using the dual antennas configured at the LoRa receiving end, the unique noise reduction algorithm designed effectively eliminates the errors caused by baseband signals and desynchronization of transmission and reception, greatly improves the perception range, and realizes human respiration detection from 25 meters away with only a pair of LoRa transceiver devices. In the scene of two walls, the detection distance can still reach 15 meters, achieving the international best performance of long-distance perception and opening a new mode of wireless sensing using LoRa signals. The first author of this paper is Zhang Fusang, an associate researcher of the Institute of Software of the Chinese Academy of Sciences and Peking University, the corresponding author is Professor Zhang Daqing and the authors of the paper also include Chang Zhaoxin, a 2016 undergraduate student from the School of Information Science and Technology of Peking University, Kai Niu, a 2016 doctoral student, Professor Xiong Jie of the University of Massachusetts, Jin Beihong, a researcher at the Institute of Software, Chinese Academy of Sciences, and Professor Lu Qin of the University of Colorado. UbiComp aims to provide a top multidisciplinary platform for international scholars, designers, and developers to explore the use of ubiquitous computing to improve and transform human experience and life. UbiComp has adopted a new publication method since 2017, and annual conference papers are accepted by IMWUT (Proceedings of the ACM on Interactive, Mobile, Wearable and Ubiquitous Technologies) journal, and all authors are invited to participate. UbiComp 2021 attracted nearly 800 scholars from 44 countries and regions to participate in the conference online.

Since joining Peking University in 2014, Professor Zhang Daqing has been committed to the research of wireless perception theory and technology, and his team proposed the first wireless perception theory based on the Fresnel zone in the world, which not only reveals the perception limit of Wi-Fi and a series of important properties of propagation in the indoor environment, but also achieves the best international performance in a series of perception applications such as contactless breathing, indoor trajectory tracking and daily behavior monitoring. This theory also provides a new theoretical basis for wireless sensing based on 4G/5G signals and LoRa signals. The relevant results have been published in the flagship journal of computer and communication sponsored by the Institute of Electrical and Electronics Engineers (IEEE) and the top conference in the field of ubiComp sponsored by the Association for Computing (ACM), which has been widely recognized by international and domestic peers.
