Prof. Hagit Messer (School of Electrical Engineering, Tel Aviv University) for Tue. Nov. 15, 11AM in the EE conf. Room (Mudd 1300), 

The concept of integrated sensing and communication (ISAC) is gaining attention in the signal processing community, especially in the context of 6G technologies. In this talk I will review the state of the art of the technology of weather sensing using existing measurements from wireless commercial microwave links (CMLs). This technology, first introduced in 2006, can be interpreted as opportunistic ISAC or as opportunistic IoT.

The fact that CML sensors are randomly distributed, and each of them samples the 2-D field of interest (e.g., rain field) as a nonlinear projection along a line, raises interesting practical and theoretical questions to their use for reliable reconstruction of the field.  In this talk I will review the state-of-the-art of the CML technology for weather sensing and will focus on future trends and on open problems.

Besides dealing with its scientific and technological challenges, I will discuss it as a test case for the interplay between academic research results and their utilization for the public good.



Hagit Messer (Life Fellow, IEEE) received the Ph.D. degree in electrical engineering from Tel Aviv University (TAU), Israel. She was a Postdoctoral Fellow at Yale University, USA and then joined the Faculty of Engineering, TAU, in 1986, where she is currently the Kranzberg Chair Professor of signal processing with the School of Electrical Engineering. During her career she has held several positions, including: the Chief Scientist at the Ministry of Science, Israel;  the Head of the Porter School of Environmental Studies and then the Vice President for Research and Development at TAU;  the President of the Open University; and the Vice Chair of the Council of Higher Education, Israel. She has also Co-Founded ClimaCell, USA, and was its Chief Scientist, until 2017. Since 2005, she has been leading a pioneering multidisciplinary research group on the use of wireless communication for opportunistic environmental monitoring.
