Reindustrialisation is a key objective for Europe. Introducing new technologies, such as collaborative robots, will make European industry more competitive, which will pave the way for industry becoming again the core of economic growth. The goal is not only to introduce robots (robots are already key elements in modern factories, especially large scale ones), but to go towards Industry 4.0. Industry 4.0, or smart factory, designates the current trend of automation and data exchange in manufacturing technologies. Its main components are cyber-physical systems, the Internet of things (IoT) and cloud computing. In a smart factory, all tools and workstation integrated into production and supply lines are interconnected continuously and almost instantaneously, so that remote control, self-configuration, self-diagnosis and self-optimisation are made possible. Once made digital, the smart factory and its reconfigurable tools enable product customization, as well as production line reconfiguration between different products. Such flexibility enables production to become at the same time massive and customisable.
New technologies involved by Industry 4.0 (collaborative and reconfigurable robots, continuous quality monitoring, factory virtualization, etc.), even though based on specific technological advances (mechatronics, 2D or 3D image processing, big data, etc.) require information exchange between various entities. To date, these information exchanges are performed either in a wired fashion, e.g., via power-line communications (PLC) / Industrial Ethernet, or in some traditional wireless fashion such as WiFi/Zigbee. In the future, massive deployment and mobile robots will make wired connection impractical (considering e.g., maintenance and the mobility of robots) and wireless solutions will become a far better option. The drawback of the current wireless communication means in the factories is the fact that they are not coordinated, not flexible in meeting the various needs of different applications, their performance is suboptimal and typically subject to interference in the complex environment, due to either the coexistence of multiple wireless communications (e.g., smartphones, WiFi access points) using the same frequency bands, or interference, which occurs at the switching-on/off of heavy factory machines, etc.
Clear5G will focus on technical solutions to address these major challenges, since the state-of-the-art wireless solutions cannot comply with them.
This project brings together some of the advanced 5G research and demonstration facilities in Taiwan and Europe. The aim is to investigate and demonstrate some of the key enablers necessary to support MTC traffic in 5G networks, in particular in the FoF environment as illustrated in the following figure. The outcomes will be verified through proof of concept implementations and demonstrations using the facilities of partners that provide and support a range of MTC use cases.
More particularly, Clear5G aims at designing, developing and validating an integrated wireless access scheme for MTC services in the FoF by achieving the following objectives:
Objective 1: To define, investigate and develop physical layer (PHY) enhancements for reliable MTC supporting massive numbers of devices, achieving extreme low latency and reduced signalling and control overhead.
Objective 2: To design and implement Medium Access Control (MAC) layer enhancements for integrated convergent access supporting low latency, high reliability, massive connection density, and high energy and spectrum efficiency.
Objective 3: To design, configure and optimize radio network architectures and management mechanisms (with potential coexistence of public and private infrastructures) to fulfil the needs of FoF applications in terms of latency, wireless networking heterogeneity, reliability, scalability and manageability. Further, energy efficiency (especially at the device side) and spectrum efficiency will also be among the major performance targets in the design of network architecture and management strategies.
Objective 4: To provide security enhancements at the physical layer, contributing to the overall security solutions in a FoF environment.
Objective 5: To validate and demonstrate the performance of the project use cases in a realistic environment using testbed facilities both in Europe and Taiwan.
Objective 6: To support the ongoing 5G Standardization
Use cases: Machine-type communications (MTC)
Verticals: Factories of the Future (FoF)
WINGS will lead the integration and prototyping activities of the project (WP5), therefore high effort will be allocated on integrating the technological components provided by WP2, WP3 and WP4 into the testbeds, while it will contribute to the validation process of the FoF prototype against the defined KPIs. In addition, it will contribute to the definition of the FoF use cases, requirements and system architecture (T1.1) and to the design of the new frame structure suitable for the strict requirements of FoF environments (T1.3). WINGS will also contribute to the design of massive access MAC protocols (T3.1, T3.2). In addition, it will contribute to the design and implementation of machine-learning and data analytics capabilities distributed in the network (T4.2, T4.3).
WINGS prospects /exploitation
The participation in Clear5G provides a great opportunity to WINGS to gain knowledge and create competitive advantage in three strategic areas for the company: technologies supporting massive machine-to-machine (M2M) communications, essential for future large scale IoT services; technologies enabling the delivery of mission critical applications and services, which are very critical for the realisation of 5G FoF service delivery scenarios; prototyping in the area of IoT, very important as WINGS will strengthen its position to future research and experimentation/prototyping/PoC initiatives. In addition, participation and contribution to the Clear5G project will help stimulate spin off projects with industrial partners. In particular, WINGS will identify opportunities for technology transfer into the factory industry, e.g., by conveying technological know-how and/or integrating the technologies and control and management tools developed and showcased in Clear5G, in future collaborations with industrial partners including vertical industries particularly in the areas of FoF, automotive, energy and eHealth.

SPEED-5G investigates in two and a half years starting from summer 2015, indoor and outdoor scenarios where capacity demands are the highest, but also where the eDSA will be the most effective at exploiting co-operation across technologies and bands including licensed, lightly-licensed and un-licensed bands.
The objective of SPEED-5G (quality of Service Provision and capacity Expansion through Extended-DSA for 5G) is to research and develop technologies that address the well-known challenges of predicted growth in mobile connections and traffic volume. A major challenge is the cost of meeting the objective, in terms of both infrastructure and deployment. SPEED-5G proposes the notion of eDSA (extended DSA), which is resource management with three degrees of freedom: densification, rationalized traffic allocation over heterogeneous wireless technologies, and better load balancing across available spectrum.
Massive IoT communications. Compared to the previous generations of networks, the Internet of Things (IoT) will have a major role in the service-compound supported by the forthcoming 5G networks. As pointed out by numerous reports and white papers (e.g. NGMN’s “Massive Internet of Things” use case or METIS’ “ubiquitous things communicating” scenario), one of the main objectives of 5G is a seamless integration of IoT at the early stage of the network architecture design.
Broadband wireless. The use case focuses on a mixture of domestic, enterprise and public access outdoor and indoor environments located in a densely populated urban area, such as a block of apartments, a square with shops and a recreation park. In this use case, a massive deployment of small cells is put in place to provide a uniform broadband experience to the users demanding high data rate and limited latency for the provisioning of applications such as high resolution multimedia streaming, gaming, video calling, and cloud services. Moreover, pedestrian users moving from indoor to outdoor environments (and vice versa), need to be supported.
WINGS ICT Solutions members' experience is exploited for the following objectives of the project:
Exploitation plans include the development of solutions which can support centralized and distributed channel selection in heterogeneous environments with learning enhancements as well. Such environments can be characterized by the dense deployment of cells and co-existence of licensed, unlicensed and 3.5GHz bands.

A group of 16 leading players in the field of telecommunications are joining forces to advance the development of a new air interface below 6 GHz for 5G networks. The “FANTASTIC-5G” (Flexible Air iNTerfAce for Scalable service delivery wiThin wIreless Communication networks of the 5th Generation) project focuses on boosting capacity, increasing flexibility and improving the energy efficiency of the next generation of mobile networks.
The aim of the two-year (2015-2017) FANTASTIC-5G project is to develop a new multi-service air interface that operates below 6 GHz frequency for 5G networks, and is:
The project supports the following use cases:
50 Mbps everywhere (MBB). This use case is representative for the scenario where high data rate in wide area coverage is required, for multiple services like Internet access, file downloading and video streaming.
High speed train (MBB+V2X). This use case is representative for the scenario where people use high quality mobile Internet not only in stationary or low-mobility scenarios, but also at higher speed (e.g. up to a range of 350-500 km/h) while using terrestrial transportation.
Sensor networks (MMC). This use case is representative for the scenario where small sensors and actuators, for example mounted onto stationary or movable objects, enable a wide range of applications related to monitoring, alerting or actuating. Typically, these devices need to transmit data only occasionally, e.g. minutes, hours, or weeks. The net payload for such applications is typically small, in the order of 20 to 125 bytes per message or even more in some special cases, and the latency requirements are often moderate, in the range of a few seconds.
Tactile Internet (MCC). This use case is representative for the scenario where a system is used by humans to wirelessly control real and virtual objects, and to accurately transmit the equivalent of human touch using the bits and bytes of data networks [ITU08.2014]. Tactile interaction typically requires a tactile control signal and audio and/or visual feedback.
Automatic traffic control / driving (MCC+V2X). This use case is representative for the scenario where advanced safety applications are used to mitigate and avoid road accidents, to improve traffic efficiency, and to support the mobility of emergency vehicles.
Broadcast like services: Local, Regional, National (BMS). This use case is representative for the scenario where systems for efficient distribution of information from one source to many destinations are used.
Dense urban society below 6GHz (MBB). This use case is representative for the scenario where a high number of users per km2 are requiring applications such as multimedia streaming with high demand in terms of traffic in urban outdoor and indoor environments.
WINGS ICT Solutions members' experience is exploited for the following objectives of the project:
Exploitation plans include the enhancement of the 5G system-level simulator of WINGS ICT in order to support the flexible, unified air-interface that the project proposes for accommodating mission critical and massive machine communications.

The exponential growth in mobile data traffic, anticipated to reach a 1000 fold increase over the next decade, together with the large diversity of applications ranging from low bit-rate and low power machine-to-machine (M2M) applications to highly interactive and high resolution entertainment applications, impose to significantly reconsider a number of distinct technical requirements on hardware (HW) and software (SW) platforms, on top of which all mobile communication-related functionalities are implemented and executed. Among the most prominent requirements, the following must be highlighted: the further improvement of quality of experience (e.g., capacity, latency, resilience) and the energy efficiency, as well as the scalability, modularity, and reconfigurability when multiple Radio Access Technologies (RAT) are considered. To achieve these requirements, highly reconfigurable HW platforms and HW-agnostic SW platforms are needed.
The overall objective of Flex5Gware is to deliver highly reconfigurable HW platforms together with HW-agnostic SW platforms targeting both network elements and devices and taking into account increased capacity, reduced energy footprint, as well as scalability and modularity, to enable a smooth transition from 4G mobile wireless systems to 5G. In order to fulfil the above overall objective, Flex5Gware addresses the following specific objectives:
In Flex5Gware, three use case families have been identified, which combined, capture fundamental aspects of the 5G system:
For each use case family, use cases have been selected as a means to validate the project's Proof-of-Concepts (PoCs) within a context of 5G:
In the context of Flex5Gware, WINGS develops a platform that identifies and proactively/reactively responds to a Dynamic Hotspot situation through the dynamic reconfiguration of 5G HW/SW systems, taking advantage of Smart City monitoring services. This platform consists of the following software modules:
WINGS prospects/ exploitation
WINGS pursues products in the areas of smart wireless access including 5G systems, device management, IoT-cloud-embedded systems based services, and SW networks management. Its main competence is the attribution of networks and devices with management intelligence. To that respect, WINGS traditionally delivers software-intensive services and products, and has also started collaborations which include also the development of hardware. Therefore, WINGS puts in the core of its activities developments that rely on software and hardware co-design and integration for the benefit of a number of vertical application areas. In this respect, the involvement in Flex5Gware will help WINGS, leveraging on its background, to design and develop intelligent solutions for building flexible and cost-effective SW platforms that can exploit the HW versatility and reconfigurability.
The advanced 5G network infrastructure needs to be highly flexible in order to meet identified but dynamic, as well as unforeseen diverse requirements imposed by new cutting-edge applications, i.e., augmented reality, connected cars, tactile Internet, to name three main ones. Dynamic reconfiguration of future 5G HW/SW systems is the answer to this challenge, as it allows system's adaptation to the very demanding and changing contexts of operation, while guaranteeing Quality of Service (QoS) and Quality of Experience (QoE). The driver of WINGS contribution to Flex5Gware is a context-aware, dynamic and cognitive HW/SW partitioning mechanism for 5G network elements and devices. The mechanism generates and exploits knowledge (e.g. prediction of a hotspot) derived by network and sensor measurements and decides upon the HW or SW execution of functions (e.g. LTE, 3GPP based PHY/MAC functions), in order to fulfill and maintain the application goals. This solution leads to high flexibility, configurability, performance and energy efficiency.
The achievement above will enhance the management/control solutions portfolio of WINGS. WINGS will also expand its activities in the direction of developing certain of its intelligence, directly in HW. This will give further exploitable competences. Moreover, there will be effort focused on scalable management solutions that will enable the optimal deployment of novel sensor based applications in a 5G context. This area will also enhance the current activities of WINGS in IoT/Cloud areas.

Investigating the potentials of Experiment-based Validation of Control Channels for Cognitive Radio Systems (EVOLVE). WINGS joined the CREW consortium as an Open Call partner in order to proceed to certain experimentation activities.
The aim of EVOLVE was to exploit various components and facilities of the overall CREW testbed in order to conduct realistic experiments for assessing and validating the performance of Control Channels for Cognitive Radio Systems (CC-CRS) in various scenarios. For this purpose, EVOLVE aimed to exploit developed CC-CRS components and interfaces and integrate them into the CREW testbed. Specifically, for various Cognitive Radio Systems (CRS) operation scenarios the exchange of corresponding messages over CC-CRS interfaces and CREW testbed facilities was monitored, so as to record performance indicators such as the total number of received and sent bytes, the signalling data bytes of every message that is sent or received, the time required for the exchange of information etc.
Regarding the obtained benefits, the user can achieve sufficient throughput and delay even when 5 hops are needed to communicate with the AP, due to the proximity of the devices. In addition, the operator can reduce its operating expenditure due to the fact that the devices can exploit their neighbours in order to maintain their QoS and there is no need for deployment of more infrastructure nodes. Finally, it should be noted that the developed solution takes into account the overhead of the signalling load. Therefore, in our experiment with 20 terminals the signalling load was around 2 Mbps.
The figure that follows shows an indicative topology of w.iLab-t testbed which was used for the experimentation. In the experimentation static and mobile nodes (robot) are considered for the evaluation.
UNIQUE will evolve, implement and experiment with a unified utility-based framework based on both QoS (network-centric) and QoE (user-centric) features and parameters, which allows to enhance, formulate and improve various advanced network operations in mobile broadband (MBB) infrastructures.
UNIQUE targets at two key runs of experiments and respective software extensions, depicting the operation and benefit of the proposed utility-based framework.
WINGS/INCELLIGENT will deliver the web-based application and work on the design of the extensions
WINGS/INCELLIGENT will implement the selection and multilink extensions required for running and evaluating the QoE-based experiments.
