Introduction This introduction is not part of IEEE Std 1900.1-2008@ IEEE Standard Definitions and Concepts for Dynamic Spectrum Access: Terminology Relating to Emerging Wireless Networks@ System Functionality@ and Spectrum Management. This standard establishes common terminology for describing emerging networks and nodes employing radio devices characterized by cognition@ adaptation@ environment awareness@ and policy-based adaptive techniques. Specifically@ the definitions provided in this document stem predominantly from a spectrum management point of view. It is anticipated that these definitions will ultimately mature and ideally achieve widespread acceptance among researchers@ manufacturers@ service providers@ regulators@ and operators. The intent of this document is to promote a common understanding of systems technology and spectrum management terms so that technologists in a variety of fields such as radio science@ including digital communications@ computer science@ and artificial intelligence@ and regulators have a common understanding of the terminology. It is the intent of this document to provide concise definitions of key terms in advanced radio system technologies and in advanced spectrum management techniques. The focus of this standard is on terms and concepts relating to emerging wireless networks@ radio@ technology@ system functionality@ and spectrum management. It was agreed that in some cases@ multiple definitions for a specific term were appropriate. Development of this standard required: a) The creation of some new terms (e.g.@ cognitive radio) and the development of definitions for these new terms. b) The development of alternative definitions for existing terms (e.g.@ dynamic frequency selection) that have been defined by other standards development organizations; these alternative definitions were required for next-generation radio and spectrum management because these terms have new meanings when used in the context of discussing advanced radio systems. It is deemed to be outside the focus of this standard to include all of the terms relevant to wireless communications systems and spectrum management (e.g.@ radio frequency and radio signal). However@ when deemed appropriate@ existing terms from the ITU-R and other IEEE documents are included for the convenience of the reader even though the term and definition is unchanged for next-generation radio and spectrum management. These terms are clearly identified in the text. This document provides normative terms and definitions to support the research and deployment of dynamic spectrum management (DSM) and dynamic spectrum access (DSA). Many factors are creating a need for DSM and DSA. Among the forces creating this need for change are as follows: ? The increasing use of wireless services and their need for spectrum. ? The increasing data load being transmitted wirelessly@ requiring increasing spectrum bandwidth. ? The emergence of multimode products such as mobile@ broadcast@ and radiolocation into single devices. ? Increasing pressure to guarantee spectrum access for priority services such as public safety while allowing other uses for that same spectrum when not in use by those priority services.
