Pol Henarejos received the Telecommunication Engineering degree from the Telecommunication Engineering High School from Barcelona (ETSETB) of Technical University of Catalonia (UPC) in May 2009. In 2012, he obtained the Master of Science in Research on Information and Communication Technologies from UPC. In 2017, he obtained the Ph.D. degree from UPC, with a distinction Cum Laude.

He joined the CTTC in January 2010 in Engineering area and he worked prototyping the physical layer communication technologies using software development. He is an expert in terrestrial and satellite technologies, such as LTE, 5G-NR, DVB-S2X, BGAN or Li-Fi. He participated in European projects such as PHYDYAS, FANTASTIC-5G and ATRIA, in European Space Agency programs (Satnex III, Satnex IV, Satnex V, SATAI) and with industrial contracts. He is also the promoter of the CASTLE Platform, the cloudified architecture for hybrid satellite and terrestrial networks.

Currently he is researching on the development of new Artificial Intelligence algorithms for satellite communications, implementation of physical stack of many standards and enabling 5G technologies on flexible multicast and broadcast communications.
