[1] Its working groups and resulting standards, numbered in the 1900 range, are sometimes referred to as IEEE 1900.X.
The effort developed supporting standards for radio and dynamic spectrum management.
SCC41 voted to be directly answerable to ComSoc in December 2010, and was renamed as IEEE DySPAN-SC.
[5] 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.
[7] 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"[8] It is a working group under the IEEE SCC41.
