Steve, I have an issue with this
question, specifically the highlighted portion 2. Should the group
develop, in addition to
the above coordinated coexistence mechanism, a media agnostic (backhaul
or wireless) management protocol (centralized and/or distributed)? Yes No This is what would be called a
leading question – it presumes the existence of the “above….” as a precondition,
whereas I believe, based on what I heard in the discussion, that the group
views the two approaches as complimentary to each other and not one dependent
on the other. Alex From: whitespace@xxxxxxxx
[mailto:whitespace@xxxxxxxx] On Behalf Of Shellhammer, Steve Marianna,
Thanks, I will set up the two straw poll questions and send them out. Steve From: Mariana Goldhamer
[mailto:marianna.goldhammer@xxxxxxxxxxxx] Hi Steve, There are big differences between my Question 2 and the existing poll
Question 2, reproduced below: “Should the group develop a media agnostic (backhaul or wireless)
higher-layer (above layer 2) coexistence protocol and mechanism?” First, my proposal is in the 802 scope (the management is allowed
in 802, while the higher layers not); secondly, it is no need for specifying
“coexistence mechanisms”, as the management may include mechanisms and they are
also covered in my Question 1. It is possible in 802 to define the primitives
(information elements) of a management protocol. The full transport
(higher-layer) protocol may be selected and recommended by the group from the
existing IETF protocols. I hope that the 802 EC will not oppose that the
standard will also include this recommendation. It is missing, in my Question 1, a definition for “agreed”. In my
view, should be agreement between the interested 802 WGs. Agreement means that
each of the relevant WGs approve the medium access protocol (and the management
part) and this is a condition for the standard approval. This approval is also
some sort of indication that the protocol will be really implemented by the
industry. Developing a standard not recognized by the interested parties does
not make sense. Regards, Mariana From: Shellhammer, Steve
[mailto:sshellha@xxxxxxxxxxxx] Why do you want to ask Question
#2? That is basically one of the two questions in the current straw poll. Steve From: Mariana Goldhamer
[mailto:marianna.goldhammer@xxxxxxxxxxxx] Hi Steve, Thanks for your offer J Probably the best will work for me the following: 1. Should there be a
coordinated coexistence mechanism that relies on an agreed medium access
protocol? Yes No 2. Should the group
develop, in addition to the above coordinated coexistence mechanism, a media
agnostic (backhaul or wireless) management protocol (centralized and/or
distributed)? Yes No Regards, Mariana From: Shellhammer, Steve
[mailto:sshellha@xxxxxxxxxxxx] Marianna,
I cannot change the straw poll once I start it since that will disturb the
results. Also, we agreed on that wording during the conference call.
I could however run another straw poll. Based on your email would the
following straw poll work for you? Should
there be a coordinated coexistence mechanism that relies on an agreed medium
access protocol? ·
Yes ·
No Steve From: Mariana Goldhamer
[mailto:marianna.goldhammer@xxxxxxxxxxxx] Steve, My preference is not included in the straw poll. A coordinated
mechanism not necessarily needs inter-system communication. Would you please include in the straw-poll a 3d variant? Should there be a coordinated coexistence mechanism that relies on
an agreed medium access protocol? In addition, the operation of such protocol may benefit from inter-system
communication or management, such that should be possible to select this option
together with the other options. In case when the management or the communications are not feasible
from different reasons, such a mechanism can still work and provide
improvements. Regards, Mariana From: whitespace@xxxxxxxx
[mailto:whitespace@xxxxxxxx] On Behalf Of Shellhammer, Steve Here is the straw poll that we developed during today’s
802.19 TVWS coexistence conference call. There are two questions. http://www.surveymonkey.com/s.aspx?sm=J72GB3TSQWDjygAAOWJHvw_3d_3d I will check it later this week and send out the results. Steve
