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 802.11. 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. If you have questions, contact the IEEE Patent Committee Administrator at <patcom@ieee.org>. Peter Ecclesine, Cisco Systems Peter Ecclesine, Cisco Systems

March 2005 doc.: IEEE 802.11-05/0223r0 March 2005 Abstract FCC Report and Order and Memorandum Opinion and Order (FCC 05-56) 3650-3700 MHz fixed and mobile at higher power http://hraunfoss.fcc.gov/edocs_public/attachmatch/DOC-257309A1.pdf http://hraunfoss.fcc.gov/edocs_public/attachmatch/FCC-05-56A1.pdf Objective of SG What is already in 802.11a/h/j Proposed Scope and Work of SG Proposed motions Peter Ecclesine, Cisco Systems Peter Ecclesine, Cisco Systems

March 2005 doc.: IEEE 802.11-05/0223r0 March 2005 Quotes from FCC DOC-257309 The Commission found that the public record developed in this proceeding supports multiple users sharing this spectrum through the use of “contention-based” protocols to minimize interference among fixed and mobile operations. New fixed and mobile stations will therefore be required to use contention-based protocols, which will reduce the possibility of interference from co-frequency operation by managing each station’s access to spectrum. The Commission concluded that this approach is a reasonable, cost-effective method for ensuring that multiple users can access the spectrum.

March 2005 doc.: IEEE 802.11-05/0223r0 March 2005 FCC Quotes (con’t) The Commission gave all licensees the mutual obligation to cooperate and avoid harmful interference to one another. Mobile stations also will be required to positively receive and decode an enabling signal transmitted by a base station. The Commission determined that this approach will ensure that mobile stations operate within range of registered base stations, thereby avoiding interference to grandfathered FSS and Federal Government stations. Fixed stations will be allowed to operate with a peak power limit of 25 Watts per 25 megahertz bandwidth, and mobile stations with a peak power limit of 1 Watt per 25 megahertz bandwidth.

March 2005 doc.: IEEE 802.11-05/0223r0 March 2005 Objective It is proposed that a Study Group be established to assess whether there is justification to form a task group to define an 802.11 standard for operation in 3650-3700 MHz Peter Ecclesine, Cisco Systems Peter Ecclesine, Cisco Systems

Proposed SG Scope Identify technical scope March 2005 doc.: IEEE 802.11-05/0223r0 March 2005 Proposed SG Scope Identify technical scope Determine impacts on IEEE 802.11, for example: Co-channel sensing requirements Definition of ‘contention-based protocols’ Signaling of enablement to mobile stations Decide whether a TG is needed, and if so define PAR and 5Criteria.

Outdoor OFDM PHY is already in 802.11a/h/j March 2005 doc.: IEEE 802.11-05/0223r0 March 2005 Outdoor OFDM PHY is already in 802.11a/h/j 802.11j specifies 4.9 GHz and 5.0 GHz FWA with licensed base stations controlling unlicensed home stations, and mandated 4 msec Carrier Sensing, DFS and TPC, Coverage Classes with air propagation times to 93 usec, multiple emissions limits and optional 10 MHz OFDM channel widths, all described and defined in Annex I and Annex J. New Regulatory Classes can extend operation to other bands and channel plans. New Coverage Classes can extend cyclic prefix protection for longer ranges and higher multi-path environments.

Proposed SG Work A decision regarding the creation of a Task Group March 2005 doc.: IEEE 802.11-05/0223r0 March 2005 Proposed SG Work A decision regarding the creation of a Task Group Creation of PAR and 5Criteria with the objective of producing an amendment which defines IEEE 802.11 operation in the 3650-3700 MHz band. Determine relationships with other IEEE 802 groups. Peter Ecclesine, Cisco Systems Peter Ecclesine, Cisco Systems
