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
<shellhammer@ieee.org> 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 <patcom@ieee.org>.

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.

Possible Future Projects
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.

Possible Future Projects
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.

Possible Future Projects
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.

layers and the controls to be made available in the device to
allow various network management techniques.
Others?? – Other standards required to develop,
qualify and support DASM systems.
