Deliverable D4.7: Final result
Abtract: This deliverable reports the final results of the WORTECS project. This includes the Fibre-Wireless-Fibre Proof-of-Concept (PoC), the 240GHz radio frequency (RF) link, Video conversion and compression, Propagation modelling software, and the Optical Wireless PoC. This deliverable focuses on Proof-of-Concept (PoC) communication systems based on wireless communications for multi-Gigabit per second and beyond wireless transmission. The main objective is to present the features of the developed PoCs and discuss the test results in terms of throughput, latency, positioning, capacity and coverage. These PoCs are expected to be used in a Heterogeneous Network (HetNet) architecture, for cooperation or aggregation between different Wireless Access Technologies (WAT) providing seamless user connectivity.

Deliverable D4.6: Radio communication proof-of-concept
Abtract: In this deliverable, the Proof of Concept (PoC) for the sub-terahertz radio, multi-gigabit modem and video compression system is presented. The radio system works in the 240 GHz band and is developed in the IHP’s SiGe BiCMOS technology. A separate transmitter and receiver with on-chip antennas were designed and produced. Further, transmitter and received, working in the same 240 GHz band and having 4 on-chip antennas configured as uniform linear array, capable of beam steering were also designed and produced. These chips are intended to be used as standalone, or in combination of multiple chips, in order to create a larger antenna array. The baseband processor, i.e. the multi-gigabit modem, was developed and written in MATLAB. It has the possibility to be used in a hardware in the loop simulation, where real hardware would be used for data transmission. At the end, B<>COM has developed a video compression/decompression system and implemented it on a FPGA board. This system is capable of different compression rates while at the same time offering low latency, needed for VR applications.

Deliverable D4.5: Optical Wireless Communications Proof-of-Concept
Abtract: This deliverable in project WORTECS presents Proof-of-Concepts (PoCs) for indoor Optical Wireless Communication (OWC) systems using broad and narrow optical beams. The broad optical beam OWC PoC aims to provide Gbit/s links to multiple users without the need for localisation and beam steering. Whereas the narrow beam OWC PoC, here referred to as fiber-wireless-fiber (FWF) PoC, aims for beyond Tbit/s links using tracking and beam-steering. These PoCs are tested in a real-world application scenario where virtual reality (VR) content is delivered from a video server to VR head mounted displays (HMDs) though the PoC air interfaces. The different OWC links are managed by heterogeneous network (HetNet) architecture implemented on FPGAs. The link reliability is tested through evaluation of bit error ratio (BER), achievable throughput, receiver sensitivity and coverage. The propagation model for the OWC PoCs are also presented.
Oledcomm (OLD), B<>COM (BCM) and pureLiFi (PLF) develop the Gbit/s OWC PoCs. The FWF PoC is developed by the University of Oxford (UOXF). The PoCs are managed by HetNet board programmed by IHP. Virtual Reality (VR) or Mixed Reality (MR) use case is shown with the help of Video Converter (VC) board and Virtual Reality content from BCM. Propagation model first results are presented by the University of Las Palmas (ULP).

Deliverable D4.2: Radio communication prototype
Abtract: This deliverable presents the parts needed for demonstrating the radio system functionality, envisioned in the WORTECS project. Two radio demonstrators are planned.

The second should use 240 GHz analog frontends and reuse the baseband and MAC processor functionalities from the first demonstrator. In this deliverable the simulation results as well as the hardware in the loop results for the developed multi-gigabit baseband processor are shown. Further the implementation details of the developed real-time radio communication system are given.

Deliverable D3.2: Common Analog and Digital Baseband Design for Flexible Radio and Optical Transceiver
Abtract:This deliverable focuses especially on radio and optical transmissions. The main issue of this document is to try to find a common architecture between the radio and optical transmitter in order to mutualize as much as possible the implementation.
Starting from the analysis of the propagation channel characteristics of both systems, we argue about the choice of the modulation format when also taking into account some material constraints issued from the hardware components. Then, Tx and Rx description and limitations of analog radio and optical parts are pointed out before describing the main elements composing the radio and optical baseband system physical layer. In conclusion, we propose three main possibilities for mutualizing the radio and optical transmitter platforms.
