DYSPAN-P1900.4 - Architecture and Enablers for Optimised Radio & Spectrum resource usage

The purpose of 1900.4 is to address radio resource management, reconfiguration management in composite wireless networks comprising multiple radio access technologies. It addresses the optimization of resources in both fixed and dynamic spectrum access contexts. 1900.4 defines a policy-based management framework for decision making. The IEEE Std 1900.4-2009 was published in February 2009. Since April 2009, the 1900.4 working group is working on two projects: -P1900.4a is an amendment of 1900.4 for architecture and interfaces for dynamic spectrum access networks in White Space frequency bands -P1900.4.1 specifies the protocols, descriptions of interfaces and service access points corresponding to the architecture defined in IEEE Std 1900.4-2009.
