The widely-recognized essential features of the emerging 5G network compared with 4G networks include: 1000 times larger system capacity, 1/1000 power consumption, 10 Gbps peak rate and 1 ms end-to-end delay, while the innovation in transmission technologies is the basis in achieving this goal. The research carried out in this project can be divided into three areas: 1) New transmission architecture and protocol design for 5G networks 2) Green-transmission enabled 5G network technologies, 3) Advanced spectrum-sharing and smart transmission strategies in 5G networks. The proposed architectures, protocols, algorithms, techniques, and schemes are validated and evaluated through simulation platform and demonstration systems. Through this project, we expect to not only build theoretical foundations for 5G networks, but also to provide high-quality training opportunities for graduate students and engineers both in Finnish and Chinese Universities/Research Institutes.

Due the rapid increase in mobile and machine type data traffic the densities of networks are growing fast and deployment of local Ultra Dense Networks (UDNs) is seen as a viable solution in 5G framework. In this project we will consider the fundamental 5G challenges including 1) development of connectivity and control structures for high carrier frequency systems, 2) design of new low-latency, lowenergy 5G radio interface, 3) design of novel cooperative communication, beamforming and massive MIMO principles, 4) development of resource allocation principles for layered UDN deployment and 5) design principles enabling energy efficient UDN. We study these topics especially from indoor connectivity and machine type communication perspectives.

As of the time 14:46, March 11, 2011, Tohoku, Japan was hit by a massive earthquake. The epicentre of the earthquake was located to be undersea off the coast of Japan, and the magnitude-level was 9.0. The first earthquake also triggered a series of subsequent big earthquakes. Altogether, these earthquakes caused huge trembling on the Japanese mainland, reaching magnitude-level 7 at Kurihara City in the Miyagi prefecture, and Level 6 across many places in Tohoku. Following these huge earthquakes, those areas facing to the Pacific Ocean over the entire Tohoku area and also a northern part of Kanto areas were hit by unpredictably huge Tsunami waves of up to 40 m height. While travelling up 10 km inland, these waves caused thousands of deaths and severe damage of private and public infrastructure.

Project focuses on a wireless body area network (WBAN) as a core of ideal ubiquitous healthcare infrastructure, which can provide us new paradigm to create innovations for future healthcare in academia and industry by employing advanced wireless technologies which Finland and Japan have been leading in a world. WBAN is a crucial wearable and implant network sensing various vital data for diagnosis and controlling actuators for health treatment around a body, and constructs a ubiquitous healthcare network combining with existing radio, and optical, networks such as a mobile cellular network and Internet. The research is divided into three paradigms: Dependable wireless communication in healthcare applications, developing the IEEE802.15.6-2012 standard, and improving the efficiency of clinical approval for compliance for novel WBAN devices.

In this project, we aim at developing a new theory for the new generation of electric power systems, also known as smart grids. Such a technology uses the information and communication technologies to exchange data within the grid, allowing for interactions between its elements as well as the humans who also play an important role. These interactions form a network structure among the diverse system elements based on fixed rules (e.g. physical laws) and adaptive relation rules guided by the available (estimated, filtered and/or processed) information (e.g. human behavior). Therefore, we need to go further than the simple analysis of the technology and thus we should include the human interactions with the power grid to have a proper picture of its dynamics.

The subject of this research work is the design and development of novel applications and services targeting wireless body area networks for health and medical-care applications to be used in the healthcare facility and home. The project focuses on realizing a number of areas including a channel model for tissue implanted device and onbody sensors for wireless body area networks. A central component of wireless body area networks is an antenna and there are several issues to consider when designing an antenna for WBAN’s applications, including power consumption, size, frequency, biocompatibility and the unique RF transmission challenges posed by the human body.

The use of wireless technologies has a lot of potential in finding new home-care related solutions, as well as in improving efficiency in hospitals. Number of applications is monifold both in medical and healthcare, e.g., a possibility of monitoring parameters at home and hospital. Self-care, selfmanagement and cost effectiveness will be the key factors towards the development of these new technological solutions. One example of utilizing wireless technologies leads to distributed hospital concept, in which measurement done at home are sent automatically to healthcare units database, and doctors or nursing staff obtain alarms when necessary. Wireless body area networks (WBAN) have been seen as a future implementation scheme of measuring human physiological parameters. Small and low power sensors installed on-body, or even in-body, are connected to each other and out-of-body using energy efficient wireless communication technique. Wireless connection will allow patients to move around, but still allowing the controlling capability of the nursing staff. The developed system can be transferred from hospitals to home due to the well defined interfaces between the WBAN and the access point of backbone network. In the project, suitable transceivers and network solutions for WBANs are investigated starting form channel models
