Phone: +34 93 645 29 00

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.

He is the head, promoter and maintaner of the testbed CASTLE Platform®, a platform for cloudification of wireless standards. Since 2015, he worked in the following tasks:

– 2016: construction of the initial testbed. It consisted in a cluster of 5 servers, 4 USRP, a router, clock & PPS synchronizer and a rack. Each component was programmed individually.
– 2017: LTE, link level.
– 2017: additional cluster on intensive computation.
– 2017: satellite reception, 4-POL in real-time.
– 2017: BGAN standard, link level.
– 2018: satellite backhauling. Two independent satellite full-duplex GEO satellite links, provided by Hispasat.
– 2018: Visible Light Communications enhancement. It allows to broadcast videos in real-time via visible light.
– 2019: E2E 4G LTE-A network with commercial UE (mobile phones).
– 2019: AI & ML cluster for intensive computation.
– 2019: Integration of CASTLE services via REST.
– 2019: DVB-S2X transmission & reception in real-time, with commercial receivers.
– 2019: remote adaptive MODCOD DVB-S2X broadcast via AI.
– 2020: mmWave. It includes a bi-directional 32×32 beamforming front-end at 26-30 GHz. This was programmed to perform beamforming remotely in real-time.
– 2020: satellite upgrade, including a satellite emulator.
– 2020: 5G-NR Release 16 full E2E network, with CA support, NB-IoT and LTE-M.
– 2020: construction of a VLC white room.
