1 3650-3700 MHz FCC Action Date: 2006-05-15 Authors: May 2006 May 2006
doc.: IEEE /0668r0 May 2006 MHz FCC Action Date: Authors: Notice: This document has been prepared to assist IEEE 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 Patent Policy and Procedures: The contributor is familiar with the IEEE 802 Patent Policy and Procedures < 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 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 Working Group. If you have questions, contact the IEEE Patent Committee Administrator at Peter Ecclesine, Cisco Systems Peter Ecclesine, Cisco Systems

2 May 2006 doc.: IEEE /0668r0 May 2006 Abstract FCC Report and Order and Memorandum Opinion and Order (FCC 05-56) MHz fixed and mobile at higher power What is in What is in Law 47cfr 90 subpart z Proposed Purpose, Principles and Outcome/Vision Peter Ecclesine, Cisco Systems Peter Ecclesine, Cisco Systems

3 May 2006 doc.: IEEE /0668r0 May 2006 Quotes from FCC DOC 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.

4 May 2006 doc.: IEEE /0668r0 May 2006 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.

5 May 2006 Types of Stations     Fixed stations for fixed service are registered, and do not move from their civic address; and the dot11 equivalent is either an AP (a portal) or a station     Base stations for mobile service are registered, and do not move from their civic address; and the dot11 equivalent is an AP.     Mobile and portable stations for mobile service are not registered, and the dot11 equivalents are stations. Both are limited to 1 watt/25 MHz EIRP, and may operate only if they can positively receive and decode an enabling signal transmitted by a base station. (Refer to FCC sections 51-53). Portable stations are those that operate within 20 cm of human contact, while mobile stations are those that operate at distances greater than, or equal to, 20 cm from human contact.

6 Outdoor OFDM PHY is in 802.11REV-ma
May 2006 doc.: IEEE /0668r0 May 2006 Outdoor OFDM PHY is in REV-ma 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 masks and optional 10 MHz OFDM channel widths, described and defined in Annex I and Annex J. REV-ma is extending Regulatory Classes to ISM bands, including antenna gain rules in ISM bands Peter Ecclesine, Cisco Systems Peter Ecclesine, Cisco Systems

7 Proposed TGy Tasks Agreement on Purpose, Principles, Vision
May 2006 doc.: IEEE /0668r0 May 2006 Proposed TGy Tasks Agreement on Purpose, Principles, Vision Determine impacts on IEEE , for example: Signaling of enablement to mobile/portable stations 109 The industry will need to address several issues as part of this process, including the characteristics of the enabling signal and an appropriate time limit within which a mobile may transmit before it must again receive and decode the enabling signal. How portables (IBSS) should function Emissions masks at band edges Draft an informative annex describing operation in MHz band Create draft Annex I and J text for MHz Peter Ecclesine, Cisco Systems Peter Ecclesine, Cisco Systems

8 Proposed TGy Purpose, Principles
May 2006 doc.: IEEE /0668r0 May 2006 Proposed TGy Purpose, Principles Purpose : the Task Group should create an amendment whose implementation in solutions is likely to receive FCC approval for operation in MHz under the 47 CFR 90 subpart z rules. Principles : If the FCC changes the rules, the Task Group should change the amendment accordingly. The amendment should not duplicate functionality that is being standardized in other Task Groups that are likely to complete before y. (Examples include parts of k and w) There is no need for backwards compatibility with 2.45 GHz ISM operation. The amendment should exclude some optional MAC and PHY behaviour, e.g. Point Coordination Function, FH, DSSS, and ERP. Peter Ecclesine, Cisco Systems Peter Ecclesine, Cisco Systems

9 Proposed Vision/Outcome
May 2006 Proposed Vision/Outcome Use the OFDM PHY with 5-, 10- and 20-MHz channel widths, and extend DFS to operate with other primary band users, to specify the basis for a system that the FCC can approve for operation in the US MHz band. Peter Ecclesine, Cisco Systems

10 May 2006 doc.: IEEE /0668r0 May 2006 TGy Motion Move that TGy adopt the Purpose, Principles and Vision/Outcome stated in 06/0668r0 slides 8 and 9 Peter Ecclesine, Cisco Systems Peter Ecclesine, Cisco Systems
