Cognitive Radio in Public Safety and Emergency Applications
Journal Title: INTERNATIONAL JOURNAL OF ENGINEERING TRENDS AND TECHNOLOGY - Year 2013, Vol 4, Issue 4
Abstract
During disaster and emergency conditions traditional communication facilities get impaired but it is important to have communication between all the first responders. In such situations wireless technologies offer a suitable way for communication. The emergency communications and disaster relief works create high traffic load and which in turn leads to congestion also network capacity and coverage are the major drawbacks of traditional wireless technologies. As it is known that the spectrum is partitioned and allocated for different purposes, not all the spectrum is used in particular space or time and the unused spectrum can serve the demand in need. “Cognitive radio” which is an intelligent wireless communication system can find spectrum holes (unused spectrum bands) and uses them for communication there by facilitating the effective use of spectrum. So this paper discusses the application of cognitive radio as a solution for communication in Public Safety services and Emergency Communications
