Leveraging optical concepts and photonic integration techniques, TERAWAY 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 these bands into a common pool of radio resources that can be flexibly coordinated and used.

The use of photonics will enable the development of multi-channel transceivers with amplification of the wireless signals in the optical domain and with multi-beam optical beamforming in order to have a radical increase in the directivity of each wireless beam. In parallel, aiming to take the most out of the THz technology and enable its commercial uptake, the project will develop a new software defined networking (SDN) controller and an extended control hierarchy that will perform the management of the network and the radio resources in a homogeneous way with obvious benefits for the network performance and energy efficiency and with possibilities for the provision of network slices in order to support heterogeneous services.

At the end of this development, TERAWAY will make available a set of ground breaking transceiver modules including 4-channel modules operating from 92 up to 322 GHz, with possibility to offer 241 Gb/s total data rate, to have more than 400 m transmission reach in the THz band (and few Km in the lower bands), and with 4 wireless beams that can be independently steered and establish BH and FH connections between fixed terrestrial and moving network nodes. The TERAWAY transceivers will be evaluated at the 5G demo site of Aalto University in Finland, under an application scenario of communication and surveillance coverage of outdoor mega-events using moving nodes in the form of heavy-duty drones.

To that end, researchers from the Department of Communications and Networking (Comnet) of School of Electrical Engineering, Aalto University, will play a number of roles in the implementation of the TERAWAY project. These roles include leadership of work package (WP7) that will carry out the field trials in Finland.
