In the past decade, cognitive radio technology has revolutionized our view of opportunities in wireless communications to a great extent. The key motivation behind this technology is to increase the spectral utilization and to optimize the use of radio resources. As cognitive radios are clearly emerging as a strong technological and regulatory opportunity, the research and development is being promoted rapidly throughout the wireless industry and in the academic research arena. Correspondingly, the standardization and regulation activities are also being initiated in many parts of the world in the interest of having efficient spectrum management and utilization. Although many of the initial proposals have been led by US based groups and by FCC, other continents have started to enter to the game. Europe has become more active partly through European Union funded projects. One of the strengths in some of these projects is also a close cooperation between academia and industry, which builds up a critical mass towards commercially exploitable standardization. The future impact of cognitive radio technology is still under discussion especially for commercially viable prototypes and future products and its implications on standardization.
In line with the objectives stated above, we propose a panel session on “Future Requirements of Cognitive Radio in the field of Commercialization and Standardization” bringing together a number of experts from different domains focusing on the future requirements for cognitive radio technology by covering the following relevant topics.
- Cognitive Radio and future implications
- Validation and Standardization efforts on cognitive radio
- True exploitation in commercialization
- Commercially viable model and proof-of-concept
- Stakeholder interests
- Roadmap of cognitive radio
The panel aims at providing lively discussions on what is going on in the listed topics. We plan to draw in participants from flagship projects in Europe, and further enhance the panel with a member from a standardization body and/or non-European project. We would like to also stress out that European Union (RAS-cluster) funded projects and participants are not necessarily “Europe centric”. Some projects include participants from outside Europe, and the selected panelist will provide also global perspective to the topics.

T1: Green Communications and Green Spectrum: Is Cognitive Radio an Enabler or Anyone else?

Nowadays, the whole world of telecommunications and information communities is facing a more and more serious challenge, namely on one side the transmitted multimedia-rich data are exploding at an astonishing speed and on the other side the total energy consumption by the communication and networking systems/devices and the relevant global CO2 emission are terribly increasing. It has been pointed out that “currently 3% of the world-wide energy is consumed by the ICT (Information & Communications Technology) infrastructure that causes about 2% of the world-wide CO2 emissions, which is comparable to the world-wide CO2 emissions by airplanes or one quarter of the world-wide CO2 emissions by cars”. According to the recent research report, energy costs account for as much as half of a mobile operator’s operating expenses. Therefore, telecommunications applications can have a direct, tangible impact on lowering greenhouse gas emissions, power consumption, and achieve efficient recycling of equipment waste. Moreover, to find radio network solutions that can improve energy-efficiency is not only benefit for the global environment but also makes commercial sense for telecommunication operators supporting sustainable and profitable business.
Gratifyingly, the emerging Cognitive Radio (CR) system and techniques are potentially capable of contributing to solve the abovementioned problems for realizing “Green Communications”. Basically, Cognitive Radio is characterized of an adaptive, multi-dimensionally environment-aware, autonomous radio system empowered by advanced intelligent functionality, which interacts with its operating environment and learns from its experiences to reason, plan, and decide future actions to meet various needs. This approach can lead to a significant increase in radio resource (spectrum) efficiency, networking efficiency as well as energy efficiency under various key constraints. Within the framework of “Green Communications”, a number of CR-enabled key approaches can be expected towards persistent awareness of the strict energy constraints, including energy-efficient network architecture & protocols, energy-efficient CR transmission techniques (e.g., reduced transmission power & reduced radiation), cross-layer optimization methods, and opportunistic spectrum sharing without causing harmful interference pollution (i.e. Green Spectrum).
This special panel is aimed to provide a unique platform to discuss not only the current status and the relevant technical challenges within various energy-efficient wireless access approaches, including but not limited to CR-enabled solutions, but also to make out a roadmap for the future “Green Communications” era. It is planned to bring together the key-players coming from the industry, academy, and government bodies around the world with various backgrounds and expertise, while targeting for deeply addressing various significant aspects of “Green Communications” and their potentially enabling technologies.
