SEMIOTIC

SEMIOTIC aims to orchestrate the communication and the data analytics for Internet-of-Things (IoT) into a meaningfully connected system. SEMIOTIC will optimize the interplay between data communication and data analytics processing based on the value and significance that the specific portion of data has for its end usage. SEMIOTIC comes at a time of rapid expansion of various IoT systems that can be segmented into two large sets: massive IoT systems and reliable low-latency IoT systems. In both types of systems there is a potential to improve the use of the communication resources and the accuracy of the data analytics. The two overall objectives of SEMIOTIC are: (1) decrease the overhead associated with various metadata used in the communication protocols; (2) minimize the resources utilized by irrelevant data. This can lead to dramatic efficiency improvement in the overall system, especially visible in IoT use cases that require low latency, such as real-time data processing and augmented reality.

The central element of the approach in SEMIOTIC is to revise this relationship and utilize co-design of the two layers (modules) in order to improve the overall efficiency, see Figure 1. The white blocks depict a two-way communication model that is based on the classical model of Shannon [20], valid when the protocol information is negligible, the source bits are ideally compressed, and all source bits are relevant for the destination. With the addition of the two modules, data model and analytics, and protocol information, SEMIOTIC generalizes the communication model to account for the cost of the metadata as well as the meaningfulness of the data communicated. The instances of the model from Figure 1 can be vastly different depending on the actual scenario.

The expansion of IoT systems will lead to massive data produced from a vast variety of connected devices and sensors, thus providing unprecedented knowledge about the state and processes of our physical world. For example, environmental sensor data can give high-resolution information about farming conditions, location/air sensors can provide detailed real-time information about traffic /pollution, while embedded industrial sensors provide the state of an industrial manufacturing process. This can be used to optimize the processes and improve the knowledge/insights about them. However, curently data communication and data analytics are modules that are optimized separately, which may lead to highly inefficient operation. As a representative example, real-time data stream mining puts an upper limit to the amount of data arrivals per unit time in order to be able to process all incoming data from a large number of sources. On the other hand, communication protocols aim to maximize the throughput, expressed as the number of data units per second that are delivered to the data analytics module. This can end in a paradox, where the a large population of devices occupy excessive communication resources in the radio spectrum to deliver data that is eventually not used.

One5G

Thirteen leading telecommunications innovators have joined forces to advance the development of new radio technologies for 5G (5G New Radio – 5G NR). The European research project ONE5G* focuses on boosting the capacity of mobile networks, improving their energy efficiency and enabling a variety of new vertical use cases in dense urban areas as well as in rural environments. ONE5G has received eight million Euros in funding from the European Commission under the EU’s “Horizon 2020” initiative to drive research that enables a swift move towards 5G NR and advance digitization. The aim of the two-year project is:

- To propose 5G NR extensions for standardization which enable high-performance, cost-efficient wireless services in ‘Megacities’ – e.g. dense urban environments with very heterogeneous requirements – and ‘Underserved Areas’— e.g. less populated and with relatively homogeneous requirements.
- To develop advanced 5G technologies and enhancements, beyond release 15 of 3GPP, which will deliver the first set of 5G standards in 2018. These advanced technologies include future-proof access schemes, advanced massive MIMO enablers and link management
- To deliver on 5G NR performance optimization schemes for successful network deployment and operation with a focus on improved performance experience for both, the network operator and the E2E user;
- To identify and improve the cost driving elements in roll-outs and operations in order to allow for the sustainable provision of wireless services in underserved areas under constrained circumstances.

Fantastic-5G

Fantastic-5G

A group of 16 leading players in the field of telecommunications joined 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 will focus on boosting capacity, increasing flexibility and improving the energy efficiency of the next generation of mobile networks.

Future mobile networks need to become even more flexible and efficient than 4G, 3G and 2G networks to cope with the ever-growing demands being placed on them. As consumer

smartphone and tablet devices become more diverse, and as the Internet of Things brings with it a huge increase in the amount of sensor-related traffic, a new air interface – which connects a user´s device to the mobile network and defines the way information is transmitted to and from the device – for 5G is required.

The aim of the 2-year FANTASTIC-5G project is to develop a new multi-service air interface that operates below 6 GHz frequency for 5G networks, and is:

  • Highly flexible, to support different types of data traffic
  • Scalable, to support an ever-growing number of networked devices
  • Versatile, to support diverse device types and traffic/transmission characteristics
  • Energy- and resource-efficient, to better use the available spectrum
  • Future-proofed, enabling easy upgrades to future software releases.

FANTASTIC-5G has received 8 million Euros of funding by the European Commission under the EU´s “Horizon 2020” initiative aiming to advance digital Europe.

The members of FANTASTIC-5G include service providers (Orange, Telecom Italia), component and infrastructure vendors (Alcatel-Lucent, Huawei, Intel, Nokia, Samsung, Sequans Communications, Wings ICT Solutions), universities (Aalborg University, Politecnico di Bari, Institut Mines-Telecom/Telecom Bretagne, University of Bremen) and research institutes (Centre Tecnològic de Telecomunicacions de Catalunya (CTTC), Commissariat à l’Energie Atomique et aux Energies Alternatives – Laboratoire d’électronique et de technologie de l’information (CEA-Leti), Fraunhofer Heinrich Hertz Institute (HHI)) from Europe.

Keysight

An increase in internet of things (IoT) applications utilizing machine-type communication (MTC), such as LTE-M and NB-IoT, in LTE networks is occurring and is expect to continue with much increased growth. These new types of applications result in new communication patterns, which together with the massiveness of the expected amount of devices, calls for changes in infrastructure. A device emulating multiple devices on the network is sought in order to enable performance testing of the LTE protocol with regards to MTC devices.

In this regards, this project focuses on implementing massive device emulators for LTE based networks by developing capable of running several devices in parallel and transmitting their combined signals through a common radio front-end. This functionality is achieved by splitting the physical layer of the LTE protocol into a common part for all devices, and an individual part tied to to each device.

The project “Evolving wireless cellular systems for smart grid communications” concentrates on the use of wireless cellular technologies in Wide Area and Field Area Networking (WAN/FAN) domains of the future smart grid. The main hypothesis is that the cellular technologies are mature and ubiquitous, such that they can serve as a basis to create communication solutions for smart grid services in WAN/FAN. Yet, the main challenge is that cellular technologies are optimized for human-centered traffic and do not provide the principal connectivity features required for the smart grid services, which are real-time low-latency connections, high reliability of critical connections and handling of a large number of simultaneous connections. The project objective is to remove these fundamental barriers by devising innovative principles and methods to evolve the cellular networks towards cost-effective support of the smart grid communications in WAN/FANs.

The project is funded by the Danish Council for Independent Research, grant ID: DFF – 4005-00281.

Principal investigator: Čedomir Stefanović

Project start date: April 1st, 2014. Project duration: 36 months.

Sunseed

Sunseed

Sunseed proposes an evolutionary approach to utilisation of already present communication networks from both energy and telecom operators. These can be suitably connected to form a converged communication infrastructure for future smart energy grids offering open services. Life cycle of such communication network solutions consists of six steps: overlap, interconnect, interoperate, manage, plan and open. Joint communication networking operations steps start with analysis of regional overlap of energy and telecommunications operator infrastructures. Geographical overlap of energy and communications infrastructures identifies vital DSO energy and support grid locations (e.g. distributed energy generators, transformer substations, cabling, ducts) that are covered by both energy and telecom communication networks. Coverage can be realised with known wireline (e.g. copper, fiber)or wireless and mobile (e.g. WiFi, 4G) technologies. Interconnection assures end-2-end secure communication on the physical layer between energy and telecom, whereas interoperation provides network visibility and reach of smart grid nodes from both operator (utility) sides. Monitoring, control and management gathers measurement data from wide area of sensors and smart meters and assures stable distributed energy grid operation by using novel intelligent real time analytical knowledge discovery methods. [SUNSEED logo]

For full utilisation of future network planning, we will integrate various public databases. Applications build on open standards (W3C) with exposed application programming interfaces (API) to 3rd parties enable creation of new businesses related to energy and communication sectors (e.g. virtual power plant operators, energy services providers for optimizing home energy use) or enable public wireless access points (e.g. WiFi nodes at distributed energy generator locations). SUNSEED life cycle steps promise much lower investments and total cost of ownership for future smart energy grids with dense distributed energy generation and prosumer involvement.
