The objective for the proposed research project WINNERoF is to achieve complete wireless coverage based on wireless technology expansion and user demands for high-capacity and broadband wireless access for outdoors or indoors (in-building) communications that become essential and strategic targets for the future communication networks. The future is going toward a Global Fixed/Mobile Convergence (GFMC). The demand to have a broadband capacity also wirelessly has put pressure on wireless communication systems to increase both their transmission capacity, as well as their coverage. This pressure comes also through high user demand for integrated broadband services (combining voice, data, video, multimedia services, and new value added services). The research contributions and deliverables from this project proposal are: – A feasibility study for the implementation of Wireless RoF based architecture at 60 GHz band for the future home and office network that support 1 Gb/s rates for wireless communications, the 4th generation (4G) mobile systems. – A MAC protocol for RoF based WLAN operating in the 60 GHz. – A bandwidth management schemes to enhance handover quality and bandwidth utilization. – A capacity analysis based on multi-traffic loss system. – A propagation channel model that optimizes the performance for radio links. This project will have many impacts on the research activities worldwide that are ongoing for 4G mobile systems. The influence on the standardization activities of ETSI and ITU are extremely important to come as soon as possible to obtain competitive advantages for Slovenian Industry in Telecom sectors, as well as for obtaining a top research position with other Academies in the world.
Significance for science
Recent research in the field of radio data communications in millimeter wavelength is rapid and important. In the period 2010-2012 the completion of standardization in the field of A / V transmission, WPAN and WLAN networks is expected. In accordance with the appearing standards basic communication VLSI circuits are foreseen on the market at a consumer price. The adoption of new technology will at this time create a new technological challenge, since these sets will only provide core functionality, with a sufficient degree of freedom for optimization and improvement of new services. These trends are followed by our research to exploit these technological advantages in the field of infrastructure as well as to provide new ideas and services which would be based on the mentioned technologies. The effective use of high bandwidth provided by millimeter radio technology, in addition to receiving and transmitting circuits requires comprehensive solutions of effective integration of RF modules in the network, implementation of relevant access protocols, the effective handover in the case of mobile use and optimal utilization of RF resources. The project focuses on a detailed analysis of the specifics of a millimeter-wavelength data communication channel specifics in open and closed spaces and thus allow the adjustment of operating conditions (channel equalization, MIMO systems, the impact of reflections, shadows) at MAC and service level, together with effective mechanisms for nanocell handovers. These research fields due to specifics in millimeter radio data communications itself constitute a major research challenge and opportunity for international recognition. A specific potential is identified in high speed wireless networks supporting telemedicine services. A typical application example is the surveillance of chronical patients using body sensor networks, where data can be integrated into the service using RoF in-home networks. Project research is closely related to i2010 initiative and with active involvement of project group members in EU project Omega.
Significance for the country
Millimeter wavelength data communication systems provide new intelligent system interconnections within the environment, which has a positive impact on the efficient use of energy, ecology, transport services, intelligent home and the like. Depending on the specific characteristics of electromagnetic wave propagation in the 60 GHz range, the impact on the environment as well as on the competitive services is minised. Management of new communication technologies in mm space is in particular a challenge to develop new industrial products, that actively exploit the benefits of new technology. Those areas represent only a few attractive examples of the use of intelligence in combination with high-speed ultrawideband communication channels which represent a challenge for other potential partners in the Slovenian industry and beyond. Slovenia can, based on the results of the project in collaboration with the development and industrial partners, actively participate in developing new services in those areas. Transfer of knowledge from involved project partners, especially from THYIA, which has a national project TITRES jointly with other partners (national & International) to potential partners of Slovenian industry is foreseen. Direct application of RoF and 60 GHz radio lies in the field of telecommunication equipment and services (Telekom Slovenia, Mobitel, TUS Telkom, AMIS, T2, etc.). New applications of WINNEROF technology can be found in medical industry, new telemedicine services, household products (Gorenje), automotive industry (Revoz, ATP, Iskra Avtoelektrika) and elsewhere. Given the potential of the above we propose to establish a consortium of companies that recognize the challenge of ultrabroadband wireless communications and utilize it for improvements, strategies, and innovation in their industries.
