Distinct Identity  Each SCC41 (P1900 series) standard shall have a distinct identity and does not substantially overlap or duplicate the work in other existing industry standards. 4. Achievable Scope  Each SCC41 (P1900 series) project shall have the potential to produce a mature draft within 18 months of PAR approval. 5. Balanced and committed participation  To uphold the IEEE-SA principle of open, balanced, consensus-based, inclusive participation, a project requesting approval shall be scrutinized for balance in the participants. This means that a diversity of stakeholders should be represented. Also, to ensure successful and timely completion of the standard, the project team shall demonstrate commitment to get the standard completed. 2

3. 3 3 IEEE 1900.1 WG on Terminology and Concepts for Next Generation Radio Systems and Spectrum Management Purpose  New concepts and technologies are rapidly emerging in the fields of DySPAN and many of the terms do not have precise definitions or have multiple definitions.  spectrum management,  policy defined radio,  adaptive radio,  software defined radio,  reconfigurable radio and networks and related technologies. The IEEE 1900.1 Working Group will develop a standard to clarify these terminologies and how these technologies relate to each other.

4. 4 4 IEEE 1900.1 Scope  The standard will go beyond simple, short definitions by providing amplifying text that explains these technologies from different perspectives.  The document will also describe how these technologies interrelate and can be use in a wide variety of communication service environments to achieve new capabilities while at the same time providing mechanisms supportive of new spectrum management paradigms and spectrum access. Current Status  PAR is approved in March 2005;  IEEE Draft Standard P1900.1 is in the balloting and recirculation stages.

6. 6 6 IEEE 1900.2 WG on Recommended Practice for Interference and Coexistence Analysis Purpose  The primary goal of DySPAN is to improve spectral efficiency.  This standard will provide guidance for the analysis of coexistence and interference between various radio services. Scope  This standard will provide technical guidelines for analyzing the potential for coexistence or in contrast interference between radio systems operating in the same frequency band or between different frequency bands. Current Status PAR approved March 2005; IEEE Draft Standard P1900.2 is in the balloting and recirculation stages.

8. 8 8 IEEE 1900.3 WG on Recommended Practice for Conformance Evaluation of SDR Software Modules Purpose  to provide recommended practices that will help assure compliance with requirements for spectrum use by using formal mathematical concepts and methods. The methods developed in this document will provide an initial evaluation to be used before hardware testing and will support the evaluation being developed in 1900.2.  To provide guidance for validity analysis of proposed SDR terminal software prior to programming and activation of an SDR terminal or SDR components.  To provide guidance on how to estimate the conformance with relevant specifications of software intended for deployment into a SDR terminal.  To support quality control and testing.  To assure that SDR software can be deployed with high confidence that it will operate within prescribed regulatory and operational limits.

9. 9 9 IEEE 1900.3 Scope  This recommended practice will provide technical guidelines for analyzing SDR software modules to ensure compliance with regulatory and operational requirements. Current Status Old PAR was approved on May 2005 New PAR was approved by the groups and SCC41 in July 2007.

11. 11 IEEE 1900.4 Coexistence support for reconfigurable, heterogeneous air interfaces Purpose  To improve overall composite capacity and QoS of wireless systems in a multiple Radio Access Technologies (RATs) environment, by defining an appropriate system architecture and protocols which will facilitate the optimization of radio resource usage, in particular, by exploiting information exchanged between network and mobile Terminals,  whether or not they support multiple simultaneous links and dynamic spectrum access.

12. 12 IEEE 1900.4 Scope  The standard defines the building blocks for enabling coordinated network-device distributed decision making which comprising: network resource managers, device resource managers, the information to be exchanged between the building blocks, will aid in the optimization of radio resource usage, including spectrum access control, in heterogeneous wireless access networks. The standard is limited to the architectural and functional definitions at a first stage. The corresponding protocols definition related to the information exchange will be addressed at a later stage.

13. 13 IEEE 1900.4 Need for the Project  Multimode reconfigurable devices are increasingly being adopted within the wireless industry.  The choice among various supported air interfaces on a single wireless device is already a reality today, with devices offering, for example, 2nd, 3rd generation cellular radio access technologies and 802 wireless standards.  Last but not least, devices and networks with DSA capabilities allowing the use of spectrum resource simultaneously among different systems are emerging and will be part of the radio eco-space.

16. 16 IEEE 1900.5 WG on Policy Language and Policy Architectures for Managing CR for DSA Applications Purpose  The purpose is to define a policy language (or a set of policy languages or dialects) to specify interoperable, vendor-independent control of CR functionality and behavior for DSA resources and services. Scope  The initial work will concentrate on standardizing the features necessary for a policy language to be bound to one or more policy architectures  Future additional tasks will build on this foundation to standardize how this is done in greater detail, paying special attention to interoperability concerns. Current Status  Study Group approved March 2006.  Study group A is changed to WG 5 on December 2007 SCC41 plenary
