Abstract: Aligned with 5G vision for a fully mobile and connected society, Terahertz (THz) wireless communication is envisioned as a key technology to fulfill the future demands for ultra-broad bandwidth, high-capacity, reliable and ubiquitous wireless systems, beyond 5G. TERAWAY is an H2020 5GPPP Phase III project, aiming to develop a new generation of THz transceivers that will enable to overcome current limitations of THz technology and challenge its commercial uptake and industrialization in the B5G era. Leveraging optical concepts and photonic integration techniques, will develop a common technology base for the generation, emission and detection of wireless signals with selectable symbol rate and bandwidth up to 25.92 GHz within an ultra-wide range of carrier frequencies covering the W-band (92-114.5 GHz), D-band (130-174.8 GHz) and THz band (252-322 GHz). In this way TERAWAY steps into providing for the first time the possibility to organize the spectral resources of a network within W/D/THz bands into a common pool of radio resources that can be flexibly coordinated and used. TERAWAY started on November 2019 and by its completion will make available a set of ground-breaking transceiver modules with 4-channel modules operating from 92 up to 322 GHz, offering up to 241 Gb/s total data rate with transmission reach more than 400 m in the THz band. Four (4) independently steered wireless beams will be used to establish BH and FH connections between fixed terrestrial and moving network nodes. Aiming to take the most out of the THz technology and enable its commercial uptake, the solution will be integrated by the implementation of a new software defined networking (SDN) controller responsible for the management of the network and the radio resources in a unified manner, and network services slicing.
