400 Gb/s wireless by enabling technologies for ultra-broadband (>50 GHz) wireless links.

ESR: Maria Freire


Maria Freire Hermelo received the Telecommunication Engineer degree from the University of Vigo, Vigo, Spain, in 2009 and the M.S. degree in digital signal processing from the same university in 2010.


From 2010 to 2015, she was with Galician Research and Development Center in Advanced Communications. She spent three months as Engineer in Televes. Since 2015, she has been working towards the Ph.D. degree with the Department of Optoelectronics at the University of Duisburg-Essen as one of the ESRs in FIWIN5G. She is involved in the project “400 Gb/s wireless by enabling technologies for ultra-broadband (>50 GHz) wireless links”. Her research interest includes radio-over-fiber systems and signal processing in communications.


The objective of this project is to study and develop a roadmap for enabling ultra-broadband wireless links with >50 GHz bandwidth for achieving ultra-high data rates. Currently there are two major research directions for enabling 400 Gb/s wireless. One is to concentrate on highest spectral efficiency at moderate bandwidth and moderate carrier frequencies. The other direction is to enable ultra-broadband or multi-band wireless systems that offer bandwidth in excess of 50 GHz. Here, the operating frequencies may extend even into the THz regime. This PhD project will focus on enabling ultra-broadband or multi-band wireless links for achieving 400 Gb/s wireless solutions.
