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 Working Group 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 <stuart.kerry@philips.com> 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 802.11 Working Group.

May 2006 Summary Introduction of a new action frame pair, Managed Object Request/Response Generic wrapper for SNMP protocol units Simple SNMP access to 802.11 client even when no SNMP agent implemented Think of it as “SNMP-Over-WLAN” Can only be processed when, when TGw Robust Management Frames implemented, when in State 3, and when dot11MIBObjectAccessEnabled is set to true Tim Olson et alt.

New WNM Action Frame value May 2006 New WNM Action Frame value Action field value Description 8 Managed Object Request 9 Managed Object Response 10-255 Reserved Tim Olson et alt.

Managed Object Request May 2006 Managed Object Request A Managed Object Request frames is sent from AP to STA for the purpose of communicating ASN.1 MIB data A Managed Object Request may be sent only with TGw Robust Management Frames, when in State 3, and when dot11MIBObjectAccessEnabled is set to true The information elements within the Managed Object Request frame specify the desired MIB data Subject to above conditions, Managed Object Request may be rejected only if not supported Tim Olson et alt.

Security Some Managed Object Requests need more than L2 authentication May 2006 Security Some Managed Object Requests need more than L2 authentication Multiple security mechanisms must be available, i.e. simple association is not enough Setting dot11MIBObjectAccessEnabled to on requires a non-standardized authentication on the client side that can be done by existing remote access procedures Tim Olson et alt.
