The Institute of Electrical and Electronics Engineers (IEEE) formed Standards Coordinating Committee (SCC) 41, Dynamic Spectrum Access Networks (DySPAN), which will help create technology standards for managing spectrum.
The new committee voted to assume sponsorship of the four IEEE 1900 dynamic access standards underway and a study group that may lead to a fifth standard in the series.
IEEE 1900 standards were jointly sponsored by the IEEE Communications and Electromagnetic Compatibility Societies.
"Finding solutions for spectrum crowding is a vital issue for wireless services," said Stephen Berger, president of TEM Consulting and chair of the committee.
"With exploding demand for current wireless services and many new types of services being proposed there simply is not enough spectrum using current techniques."
"Dynamic spectrum access has been demonstrated to increase the number of devices that can operate in the same spectrum space by a factor of 10, 20 or even more, compared to current devices. Implementing dynamic spectrum techniques is seen by the international communications community as vital to the future of wireless operations," said Berger.
Berger said that the explosion of commercial and military radio applications makes spectrum a precious commodity and challenges people to use this unique resource as effectively and efficiently as possible, particularly in the very crowded region below 3 GHz.
"Spectrum is usually managed through licensing that lets licensees transmit in specific bands," he said.
"But studies indicate that only 0.3 to 3.0% of the spectrum assigned this way is in use at any one place and time. This leaves a lot of room for more efficient use of the spectrum, allowing new applications to operate. DySPAN seeks to take advantage of such vacant spectrum through nimble systems that can identify and harvest for use bands that are currently under utilized. The use of such technology involves a shift in emphasis to managing coexistence among radio services."
The formation of SCC 41 reflects the importance the IEEE assigns to dynamic spectrum access. The new committee, which has the authority to sponsor standards, gives present and future DySPAN standards efforts a home of their own while drawing on the IEEE"s knowledge base in communications, electromagnetic compatibility, information technology and other areas, said the IEEE.
The IEEE says it took a leading role in creating dynamic spectrum access and cognitive radio standards starting in March 2005 by initiating IEEE P1900 standards. Four standards in this family, which will be sponsored by SCC 41, are underway:
- IEEE P1900.1 - Standard Terms, Definitions and Concepts for Spectrum Management, Policy Defined Radio, Adaptive Radio and Software Defined Radio.
- IEEE P1900.2 - Recommended Practice for Interference and Coexistence Analysis.
- IEEE P1900.3 - Recommended Practice for Conformance Evaluation of Software Defined Radio (SDR) Software Modules.
- IEEE P1900.4 - Architectural Building Blocks Enabling Network-Device Distributed Decision Making for Optimized Radio Resource Usage in Heterogeneous Wireless Access Networks.

SCC 41 also assumed responsibility for a study group exploring the creation of a testing standard for DySPAN devices that regulatory bodies can use when setting mandates for qualifying software-defined radios.
