7、his recommended practice was developed under the auspices of IEEE Standards Coordinating Committee 41 (Dynamic Spectrum Access Networks, or DySPAN) (formerly IEEE 1900 Standards Committee on Next Generation Radio and Spectrum Management). SCC 41 (DySPAN) serves as a forum for the exchange of informa

8、tion in the area of dynamic spectrum access networks and to act as a sponsor for related standards projects. Taken together, current and future activities under the SCC 41 (DySPAN) will provide standards and recommended practices for addressing the many facets and issues introduced by DySPAN. Indivi

11、n of this recommended practice (prepared by the IEEE P1900.2 Working Group) is expected to be aided and facilitated by referring to the products of the other, complementary projects under SCC 41 (DySPAN), as they are completed and published. Introduction to IEEE Std 1900.2 Perhaps the critical quest

12、ion to be answered when analyzing interference is, at what point is there harmful interference among radio systems coexisting in common spectrum assignments? As it is commonly used, harmful interference is a broad concept, combining the physical facts of a situation with the economic perspective and

13、 values of the stakeholders involved. This document seeks to bring greater understanding and precision to the term and to apply more objective criteria to its assessment, particularly in a dynamic and changing coexistence environment.a This recommended practice addresses several elements necessary f

14、or making an analysis of the potential for harmful interference. It seeks, wherever possible, to require a scientific and objective approach for an interference and coexistence analysis. It is hoped that by stating and clarifying assumptions and by providing a normalized structure for engineering an

15、alysis that the determination of the relative importance of the benefits and risks will be facilitated. aThe imprecise nature of the concept is best addressed by first determining the facts, differing assumptions that might be made, and then allowing the relevant decision-making authority to make it

16、s decision within the range of credible conclusions. This standard primarily serves to identify the agreed on facts and to propose thresholds and objective criteria for a specific scenario. In the International Radio Regulations (see IRR, Appendix 5 B18), and relevant ITU-R recommendations, the term

17、s “harmful,” “permissible,” and “accepted interference” are defined, demonstrating the consensus of that body that levels of interference exist that are acceptable under conditions of static spectrum assignment. (See the international radio regulations of the ITU-R 1.166, ITU-R 1.167, ITU-R 1.168, a

18、nd ITU_R 1.169.) This standard is intended to extend to spectrum assignments that may change dynamically, perhaps rapidly in time, depending on traffic or other local conditions, among a number of radio systems, coexisting in a common spectrum assignment. . iv Copyright 2008 IEEE.

19、d. Stated simply, an interference and coexistence analysis involves answering questions, such as: Where am I? Who else is around me? What do I have to worry about? What are my rights and responsibilities relative to others? What can help us get along? This recommended practice provides a structure a

20、nd describes a method for analyzing the interference between radio services under a variety of coexistence scenarios. Many variables to be used in this analysis will be detailed. The annexes provide helpful supportive material and examples of analysis using this document. One reason for the analytic

21、al structure specified in this document is to provide an objective and uniform framework for assessing and analyzing interference and coexistence. From this framework, an understanding is gained of assumptions, dependencies, and relative importance of the variables of the problem. In the end, a thor

22、ough interference and coexistence analysis provides an invaluable support when considering the acceptance of new technologies or systems that are to coexist in common, shared spectrum assignments. Having this understanding of the physical reality and the technical facts, economic analysis or even a

23、political formulation may be more effectively applied. To use the vernacular, you can figure out who pays whom and how much to make life good. Companies can also anticipate customer satisfaction and warranty costs for products that will be coexisting in dynamically assigned spectrum assignments. Not
