The CTTC Workshop is a biannual event that aims at gathering all CTTC researchers, so that they can disseminate their technical work and share their ideas with other CTTC colleagues. Several vibrant poster sessions are organized in this respect. In this second edition of the event taking place in November 29 at the Sunway Hotel (Sitges, Barcelona), the Workshop hosts two renown invited speakers, along with stakeholders of the local hi-tech ecosystem.
