IEEE Forms Study Group to Explore Standardization for Spectrum Occupancy Sensing Technology New IEEE 802.22™ study group to consider standardization of SOS technology for optimizing usage of radio spectrum for wireless broadband services IEEE, the world Imec presents a digital front-end component for low-cost and low-power spectrum sensing, paving the way to power-efficient cognitive radios and networks. The new results support industry’s search for increased flexibility and reliability for their next (Targeted News Service Via Acquire Media NewsEdge) HOBOKEN, N.J., Nov. 3 -- Stevens Institute of Technology issued the following news release: As proliferating wireless devices make greater demands on communications spectrum, researchers seek to develop One approach to finding the right channel is spectrum sensing, where the basestation receiver listens on the various channels to see what is taking place. If a signal within specific parameters is sensed, no transmission takes place and other channels are Presently there is a scarcity of wireless spectrum worldwide due to an increase in wireless services. Cognitive Radios are proposed as a solution to this problem. They access the spectrum licensed to existing communication services (primary users Phew. For a moment few years there, we thought any device set up to operate on these so-called white spaces-- which have been vacated following the analog-to-digital TV transition-- would be forced to use spectrum sensing modules in order to ensure that no .

Imec is offering a digital front-end component for low-cost and low-power spectrum sensing to power-efficient cognitive radios and networks. According to the firm, its cognitive reconfigurable radio solutions will benefit next-generation multi-mode "But our method is contactless." The sensing method, which is described in Nature’s Scientific Reports, involves the use of indium phosphide, which emits a terahertz signal when it becomes excited. To exploit that, the researchers layered graphene onto a Barcelona (Spain) – February 14, 2011 – Imec presents a digital front-end component for low-cost and low-power spectrum sensing, paving the way to power-efficient cognitive radios and networks. The new results support industry’s search for increased IMEC has developed a digital front-end chip for low-cost and low-power spectrum sensing, paving the way to power-efficient cognitive radios and networks. The chip has a dedicated ASIP (application-specific integrated processor) and can perform both .
