Summary and Motivation
• Administrations 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.
• However, in many administrations, 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.
• Such a Spectrum Occupancy Sensing (SOS) system will combine
information from multiple sensors along with local terrain information to
predict the spectrum occupancy patterns.
• This could lead to more efficient use of spectrum especially in places
where the information about the primary users is difficult to find.
• The SOS Study Group will explore on-going research, challenges and
aspects that require standardization.

Relevance to the IEEE 802.22 WG
• 802.22 supports
sensing, beaconing and
database access to
enable cognitive sharing
• 802.22 has defined the
MAC messaging formats
to transfer sensing
information from
Customer Premises
Equipment (CPEs) to the
Base Station
802.22 Protocol
Reference Model

Spectrum Occupancy Sensing (SOS) System
• SOS will bring the Spectrum
Sensing Functions (SSF)
and sensing related
messaging formats out of
the current 802.22 spec to
create a stand-alone system
of external sensors
dedicated to creating a
Spectrum Occupancy
Survey.
