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– Analysis of the Applicability of Cognitive Radio Technologies to

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.

NPSTC: The Collective Voice of Public Safety Telecommunications www.NPSTC.org-7-

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.

Wrapping it Up

• Expect completion of the report by Fall 06– Appear to have good participation from both industry

and PS

• CALL FOR ADDITIONAL PARTICIPATION– Both in scenario development as well as in technical

analysis

– Lots of work expected in the policy area

– Need more PS participation in forum in general• Contact Powell, Frantz or O’Hara
