Title: Operational challenges for emerging cognitive radio technologies - Wireless Devices Utilizing TV White Spaces
Abstract: Cognitive radios are finally emerging in the form of White Space devices capable of accessing spectral resources allocated for communication systems but not actually in use. Temporal and geographical information on existence of White Space is obtained from dedicated database through Internet access. Here, technological advancements enabling commercial utilization of wireless White Space devices are analyzed. However, before full scale commercial deployment is possible regulatory and techno-economical challenges exist. Current research and development, regulation, and standardization activities to overcome remaining obstacles are surveyed. Scientific community should turn attention to providing contributions for regulatory authorities in order to facilitate positive administrative decisions for cognitive radio technologies.
