Patent Policy and Procedures: The contributor is familiar with the IEEE 802 Patent Policy and Procedures http://standards.ieee.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
Wendong Hu 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 802.22 Working Group. If you have questions, contact the IEEE Patent Committee Administrator at patcom@iee.org.

Questions and Responses to 802.11
• Question 1: Doc. 11-09/1106 discusses possible issues
with the PAR and 5C submitted by Peter E
• Response: Accept document
• Proposed Resolution
– See document IEEE 802.22. 09-235 addressing the questions and

Questions and Responses to 802.11
• Question: Problem- Dates for completion are not realistic. The
dates need to be corrected (we suggest that the dates of Start
Sponsor 12-2012 and RevCom 12-2013 would be more
realistic/acceptable.)
Response: Reject comment
Explanation
No significant effort is anticipated for addressing the requirements in the
modified PAR. The date of initial sponsor ballot is expected to be 072010 and Revcom is 07-2011.
• Question - The form presented was not the correct PAR form.
The PAR modification form should be used.
Response: Accept comment
Proposed Resolution
Will use the right form:

Questions and Responses to 802.11
• Question: Scope 5.1 This standard specifies the air
interface, including the cognitive medium access control
layer (MAC) and physical layer (PHY), of point-tomultipoint wireless regional area networks comprised of a
professional fixed base station with fixed and portable user
terminals operating in the VHF/UHF TV broadcast bands
between 54 MHz and 862 MHz.
– Issue 4: “professional fixed base station” should be “professionally
installed fixed base station” – (insert the word “installed”)

Questions and Responses to 802.11
• Question: 8.1 other comments– Issue 5: Remove the following text as it is no longer necessary/needed
from the end of the first paragraph:
•
“The IEEE 802.18 Study Group chartered to develop this PAR does not believe that any
existing IEEE 802 PHY/MAC combination can meet these requirements without extensive
modifications. The Study Group has therefore concluded that placing the project in a new
Working Group is the most efficient approach..”
Response: Accept comment
Proposed Resolution
Modified document
•
Question: 5c: Distinct Identity A
– Issue 6: This text fails to distinguish among 802.16h, which will be an approved
amendment in early 2010, and 802.22 and the efforts proposed in the 802.22.3
PAR. Add distinctions between each of the three. Be aware that 802.16h clause
6.3.2.3.86 does report DTV, wireless microphones and other licensed users.
Response: Accept comment

Questions and Responses to 802.11
•
Question: 5C Technical Feasibility –
– Issue 7: There is no experience of WLAN devices operating under the control of
fixed outdoor devices reliably, and indeed the question of reliable operation
without common control is an issue in every unlicensed band.
Response: Accept comment
Proposed Resolution:
Modified text to clarify this statement
•
Question: 5C Economic Feasibility –
– Issue 8: Not all devices are autonomous, indeed the FCC ruling requires that
Master Devices contact the TV bands database before any transmission is allowed.
Change this text to include operation with a TV bands database.
Response: Accept comment
Proposed Resolution:
Modified text to clarify this statement

Questions and Responses to 802.11
• Question:2.1 Title:
– Issue 9: The Title is in properly formed. Prior to the “Part 22” it is should
be the consistent boilerplate that all 802 Standards have. Then after the
“Part 22” it should have what designates this to the 22WG and then the
specific title part for the covered technology
Response: Accept comment
Proposed Resolution:
Modified title to conform with 802.Standards

Questions and Responses to 802.16
• Question: scope to be clarified as follows - (text in Blue)
– “This standard specifies the air interface, including the medium access control layer
(MAC) and physical layer (PHY), of fixed point-to-multipoint wireless regional
area networks comprised of a fixed base station with for fixed and portable user
terminals operating in the unlicensed VHF/UHF TV broadcast bands between 54
MHz and 862 MHz (TV Whitespace).”
Response: Accept in part and reject in part
Proposed explanation/Resolution
– 802.22 WG disagrees with the reinsertion of the word “fixed”. By supporting
portable user terminals in 802.22, the wireless regional area networks can not be
considered as fixed from the regulatory point of view. 802.22 WG agrees with the
rest of the suggested changes.

Questions and Responses to 802.16
• Question: Section 19. Additional Explanatory Notes-The following
statement is not clear
– “Item 4: “Wireless Regional Area Network” (“WRAN”) - a point-tomultipoint network for operation over large, potentially sparsely populated
areas (e.g. rural areas) for fixed user terminals, taking advantage of the
favorable propagation characteristics in the VHF and low UHF TV bands
as well as for portable user terminals operating over a likely smaller area
with sufficient margin to the fixed base station.” What does “sufficient
margin to the fixed base station” imply? Shouldn’t Item 4 also address
interference requirements for portable devices as well?
Response: Accept comment
Proposed Resolution
– Modified text to make it clear
