TERAWAY introduces a number of key innovations both at the device and the system level, aiming to develop a disruptive THz technology that will address the capacity and flexibility challenges of wireless BH/FH networks.
The high-level objective of TERAWAY will be realized through the following 9 objectives:
Objective 1 | Develop a photonics-enabled platform for ultra-wideband signal generation and emission in W/D and THz bands of wireless communications
Leveraging the potential of photonics for the handling of radio signals in the optical domain with almost no bandwidth limitations, a platform will be developed for the generation and emission of broadband signals over a continuum of carrier frequencies covering the W-band (92-114.5 GHz), D-band (130-174.8 GHz) and THz band (252-322 GHz) of wireless communications. . In order to achieve the necessary level of functionality and compactness, TERAWAY will rely on photonic integration techniques and the specific combination of the polymer platform of FhG-HHI (called PolyBoard) with the silicon nitride platform of LXI (called TriPleX).
Objective 2| Develop an optical beamforming unit and a bow-tie antenna matrix on the hybrid platform for multi-beam emission of signals in W/D and THz bands
Extend the functionality of the hybrid platform through the monolithic integration of a multi-beam optical beamforming unit in the TriPleX part of it. The unit will be based on the Blass matrix architecture and will accommodate the formation of up to four independent beams by a multi-element antenna.
Objective 3| Develop a photonics-enabled platform for ultra-wideband signal detection and reception in W/D and THz bands
Develop a hybrid platform for the detection of signals in the W/D and THz bands and for their down-conversion to the baseband. The platform will ensure the same technology base at the receiver side as at the transmitter side, enabling end-to-end demonstrations of flexible, ultra-wideband transmission systems
Objective 4| Develop methods and tools, and perform the physical and system integration of multi-channel transceiver modules for the W/D and THz bands with total capacity up to 241 Gb/s (TERAWAY modules)
Develop a set of methodologies and tools for the physical integration, packaging and system integration of the four (4) transceiver modules that will be developed within the project.
Module-1: Precursor module supporting operation of only one low-bandwidth channel.
Module-2: Precursor module supporting operation of one high-bandwidth channel.
Module-3: Main module supporting one low- and one high-bandwidth channel.
Module-4: Module-4 will be an evolution of Module-3, supporting two low- and two high-bandwidth channels with two PMs, two IQMs and four photonic IQ mixers.
Objective 5| Perform the physical and system integration of network nodes (including moving nodes) using the TERAWAY modules for backhaul or fronthaul connectivity (TERAWAY nodes)
Investigate the use of the two main transceiver modules (Module-3/4) as key system blocks in nodes of future 5G networks, and perform the physical and system integration of four specific node designs (2 Fixed Nodes (FN) and 2 Moving Nodes (MN))
Objective 6| Develop tools for generation of THz path-loss maps in realistic propagation environments and methods for the localization of nodes in THz communication systems
Develop modeling methods and a comprehensive simulator for the generation of path-loss maps for THz signals inside realistic propagation environments and develop a baseline process for the calculation of the distance between a pair of nodes with high accuracy, using THz signals and a simple symmetrical double-sided two-way ranging (SDS-TWR) method.
Objective 7| Develop network management platforms and application tools, and perform the integration of the nodes inside a network system supporting different traffic and service types (TERAWAY system)
Develop a number of key management platforms and application tools in order to accomplish the integration of the TERAWAY nodes inside a functional system, the operation of this system with optimum use of network and radio resources and the accommodation of services that are relevant to the service class of eMBB and the service class of URLLC.
Objective 8| Evaluate the transmission performance of TERAWAY modules and demonstrate the operation of TERAWAY system in field trials
Characterization and evaluation of the transceiver modules using benchtop tests in lab settings and perform field trials at the 5G testbed of Otaniemi Campus in Finland, emulating the use case of an outdoor, non-recurring mega-event TERAWAY using moving nodes (MN) in the form of heavy-duty drones carrying gNBs or their radio parts.
Objective 9| Achieve substantial impact on the standardization landscape for THz communications and elaborate on a roadmap for the introduction of THz systems in commercial networks and applications.
Participate/contribute to standardization activities, organizations/bodies related to THz technology for wireless communications.
