November 2005 Liaison Report from P1900.2
Notice: This document has been prepared to assist IEEE 802.19. It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s). The material in this document is subject to change in form and content after further study. The contributor(s) reserve(s) the right to add, amend or withdraw material contained herein.
Release: The contributor grants a free, irrevocable license to the IEEE to incorporate material contained in this contribution, and any modifications thereof, in the creation of an IEEE Standards publication; to copyright in the IEEE’s name any IEEE Standards publication even though it may include portions of this contribution; and at the IEEE’s sole discretion to permit others to reproduce in whole or in part the resulting IEEE Standards publication. The contributor also acknowledges and accepts that this contribution may be made public by IEEE 802.19.
Patent Policy and Procedures: The contributor is familiar with the IEEE 802 Patent Policy and Procedures <http:// ieee802.org/guides/bylaws/sb-bylaws.pdf>, including the statement "IEEE standards may include the known use of patent(s), including patent applications, provided the IEEE receives assurance from the patent holder or applicant with respect to patents essential for compliance with both mandatory and optional portions of the standard." Early disclosure to the TAG of patent information that might be relevant to the standard is essential to reduce the possibility for delays in the development process and increase the likelihood that the draft publication will be approved for publication. Please notify the Chair <[email protected]> as early as possible, in written or electronic form, if patented technology (or technology under patent application) might be incorporated into a draft standard being developed within the IEEE 802.19 TAG. If you have questions, contact the IEEE Patent Committee Administrator at <[email protected]>.

Scope & Purpose
Project 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.
Purpose of the Project: New concepts and technologies are rapidly emerging in the fields of spectrum management, policy defined radio, adaptive radio and software defined radio. A primary goal of these initiatives is to improve spectral efficiency. This standard will provide guidance for the analysis of coexistence and interference between various radio services.

DASM Qualification Regiment – An evaluation process by which compliant implementations may be separated from non-compliant implementations. An abstracted and refined regiment producing the same information as field trials and proof-of-concept testing.
DASM Conformity Assessment System – Beyond the initial design verification, type acceptance qualification regiment there is a need to provide a full conformity assessment system to assure that fielded systems operated within specified bounds.
Policy definition - What are the restrictions in freq, power, bandwidth, time, etc for communication; how do we express them
Electronic Data Interchange (EDI) of Policy sets – Standard format for policy loads.
DASM Etiquette – An etiquette that allows cognitive radios to communicate between themselves, agree on operating modes, and exchange sensing information.

A generic radio interface – A standard that allows radio software to discover the hardware radio transmission, reception, and sensing capabilities and to control these capabilities. This allows SDR software to port across platforms more easily, and hardware to leverage new software developments.
Channel usage database – A standard that stores known transmitter information in a useful format for cognitive radios. It would define secure mechanisms for querying or broadcasting this information; and secure and distributed methods for the db to be updated by transmitter owners.
A beacon radio standard – A standard for disseminating channel usage info in an area; a transmitter beacon that is an easy to detect signal so cognitive radios could discover transmitters more easily; and a receiver beacon standard so dumb receivers (e.g. a TV) could have a simple beacon to warn off potential secondary users.

Definition of field management techniques – These standards would define field management techniques to manage and coordinate DASM systems. An example might be a standard query that a system receiving interference could issue to receive the identity, including software load and version level, of devices operating in the area..
Guide for ISO 17025 for DASM evaluation laboratories – A guide on the qualification of laboratories intending to test DASM systems.
Infrastructure Support – Coordination is needed to other bodies so that the environment is prepared for the introduction of DASM systems:
Update of ANSI C63.19 so that hearing aids are adequately tested for immunity to DASM transmissions and DASM systems can be tested for HAC.
Update of ANSI C63.9 so that office equipment can be adequately tested for RF immunity to DASM transmissions.
Update of AAMI PC69 so that implanted medical devices can be adequately tested for RF immunity to DASM transmissions.
