DySPAN

The Dynamic Spectrum Access Networks Standards Committee (DySPAN-SC), formerly Standards Coordinating Committee 41 (SCC41), and even earlier the IEEE P1900 Standards Committee, is sponsored by the Institute of Electrical and Electronics Engineers (IEEE). The group develops standards for radio and spectrum management. Its working groups and resulting standards, numbered in the 1900 range, are sometimes referred to as IEEE 1900.X. The Dynamic Spectrum Access Networks Standards Committee (DySPAN-SC), formerly Standards Coordinating Committee 41 (SCC41), and even earlier the IEEE P1900 Standards Committee, is sponsored by the Institute of Electrical and Electronics Engineers (IEEE). The group develops standards for radio and spectrum management. Its working groups and resulting standards, numbered in the 1900 range, are sometimes referred to as IEEE 1900.X. The IEEE P1900 Standards Committee was established in March 2005 jointly by the IEEE Communications Society (ComSoc) and the IEEE Electromagnetic Compatibility Society (EMC). The effort developed supporting standards for radio and dynamic spectrum management. On March 22, 2007 the IEEE Standards Board approved its reorganization as Standards Coordinating Committee 41 (SCC41), Dynamic Spectrum Access Networks (DySPAN). The IEEE ComSoc and EMC sponsored this effort, as they did for IEEE 1900.The IEEE 1900 Committee ceased to exist at the inaugural meeting of SCC41 in April 2007. The work of the IEEE 1900.x Working Groups continued under SCC41.SCC41 voted to be directly answerable to ComSoc in December 2010, and was renamed as IEEE DySPAN-SC. At its December 2010 Meeting, the IEEE Standards Association Standards Board (SASB) approved the transfer of projects to the Communications Society Standards Board. DySPAN-SC focuses on Dynamic Spectrum Access and associated technologies. Due to the strong inter-relationships between such topics, it also touches on other areas such as Cognitive Radio. IEEE DySPAN-SC currently oversees the following standards development working groups: Proposed standards have 'P' prepended to the name until they are ratified. The first to be published was 1900.2 in July 2008.Next was 1900.1 on September 26, 2008.Then 1900.4 was published on February 27, 2009.Work then began on amendment P1900.4.1a for dynamic spectrum access networks in white space frequency bands, and P1900.4.1 for interoperability between components of the IEEE 1900.4 system.The 1900.6 standard was published on April 22, 2011, and work began on an amendment 1900.6a. The IEEE 1900.4 Working Group is on 'Architectural Building Blocks Enabling Network-Device Distributed Decision Making for Optimized Radio Resource Usage in Heterogeneous Wireless Access Networks' It is a working group under the IEEE SCC41.
