Overview
• Since 2004, the Software Defined Radio Forum (SDRF)
has had a Working Group dedicated to Cognitive Radio
(CR) Technologies
– Chair John Grosspietsch (Motorola)
– Vice Chair Sean O’Hara (SRC, NPSTC)
•
This WG keeps a close liaison with the Interoperability
Committee through John Powell (also Chairman of
SDRF)
– Both have been pushing for work in the PS area (PS-SIG as well)
• This year, one of the main work items will be related to
public safety

Public Safety Operations

Why Care about CR?
• Cognitive Radio (CR) technologies are being embedded
into our US military capabilities
– CR being assimilated into commercial communications markets
as well.
• However, Homeland Security and Public Safety
Communications are behind these other groups in both
understanding and integrating these capabilities into
their operations.
• This is unfortunate, as many of Public Safety’s current
communications interoperability and spectrum resource
issues might be addressed through the utilization of
these technologies.

What will the Study Consist of?
•
The study will consist of an investigate into the application of SDR and
Cognitive Radio to Public Safety’s needs, through the examination of
several scenarios.
•
Will examine scenarios that leverage cognitive radio capabilities and
technologies to support Public Safety operations.
•
Scenarios will be selected as a joint efforts between the SDRF Public safety
Special Interest Group (PS-SIG), Chaired by Fred Frantz and the CRWG
– NPSTC Participation (Powell, Martinez, Frantz, O’Hara etc)
– Will probably use SAFECOM scenarios as applicable (perhaps with some
modification if necessary)
•
The WG will then analyze and asses how cognitive radio technology can
provide public safety solutions to their communications and interoperability
issues.
– Identify Current Capabilities
– Identify Research and Development Needs

What will be Examined?
• At a minimum, the following Cognitive Radio
(CR) technology areas will be examined for each
scenario selected:
– Spectrum RF Characterization:
• Portions of the CR System that determine spectrum
occupancy, waveform identification, physical geolocation of
communications nodes and other related functions
– Connection Rules:
• Portions of the CR System that determine how nodes are
connected, which communications are routed to which nodes
and how policy or rule based decision processes support the
communications functionality.

What will be Examined (cont,)?
– User Interface:
• Portions of the CR System that determine spectrum
occupancy, how the CR interacts with the environment and
the users. It will tailor the operational capabilities of the GUI
and SDR/CR platform to meet the needs of Public Safety
incident commander’s responding to complex operations and
situations.
– Digital Filtering – PHY/MAC Functions:
• Waveform decomposition and information processing for
routing to appropriate frequency bands, waveforms and
communications nodes.
– Networking Functions:
• Routing functionality and information transport mapping.

What will be Examined (cont,)?
• For each of the areas, the Working
Group(s) will
– Research technology capabilities,
– Perform analyses and simulations, as
necessary, and
– Come to conclusions regarding requirements,
current capabilities, and future development
needs.
