IEEE, the world's largest professional organization dedicated to advancing technology for humanity, today announced the formation of the IEEE 802.22™ Spectrum Occupancy Sensing (SOS) Study Group. SOS is a promising technology for optimizing the usage of radio frequency (RF) spectrum for wireless broadband services.
“This new study group, under the guidance of the IEEE 802.22 Wireless Regional Area Networking Working Group, will explore the standardization of SOS technology,” said Dr. Apurva N. Mody, chair of the working group. “Standardization could lead to the more efficient use of spectrum, especially in places where the information about the primary users is difficult to find. To better understand the standardization requirements, the study group will explore ongoing research and the various challenges associated with the technology.”
Recently, the IEEE 802.22 working group—recipient of the IEEE Standards Association (IEEE-SA) Emerging Technology Award—completed and published IEEE 802.22-2011™ “Standard for Information technology—Local and metropolitan area networks—Specific requirements—Part 22: Cognitive Wireless RAN Medium Access Control (MAC) and Physical Layer (PHY) specifications: Policies and procedures for operation in the TV Bands.”
Mody added: “The study group will use the IEEE 802.22 standard as a baseline for future SOS standards and efficient use of the technology. Administrations from all over the world are looking to improve the utilization of the spectrum. White Space Database access is one of the techniques to enable spectrum sharing and the use of unused frequency bands, also known as the white spaces.”
The standard focuses on cognitive radio-based wireless regional area networks (WRANs) that provide broadband access to global wide regional areas and reliable, secure high-speed communications to underserved and unserved rural communities. As a result, IEEE 802.22 supports sensing, beaconing and database access to enable cognitive sharing. SOS is intended to bring the Spectrum Sensing Functions (SSF) and sensing-related messaging formats out of the current IEEE 802.22 standard to create a stand-alone system of external sensors dedicated to creating a spectrum occupancy survey.
“For example, the locations and characteristics of the radiators are not well documented. Individual and collaborative spectrum sensing is one of the tools to complement the information contained in databases to create an accurate spectrum occupancy survey, which would combine information from multiple sensors along with local terrain information to predict the spectrum occupancy patterns.”
The IEEE 802.22 SOS Study Group is seeking interested participants for the development of the scope and purpose for possible standards. The Project Authorization Request (PAR) development work will start during the IEEE 802 interim meeting 19-24 January 2014 in Los Angeles, Calif.
