Ground rules for straw poll
• Only recorded participants as of the end of the January IEEE meeting will be allowed to participate
• The answers to the questions will be tabulated and included in Section 11 of the final report
• Each question will have a comment field to allow text input
• These comments will also be included in the final report. The name of the commenter will be included UNLESS the respondent says to omit his/her name

Straw poll question #1
Objective of the Tiger Team: “Create a document that describes and quantifies possible coexistence mechanisms between DSRC and extensions of the 802.11 base standard in the proposed UNII-4 band, if the FCC allows such band sharing in a future R&O.”
Do you believe that sharing of the 5.9GHz band by unlicensed (Part 15) devices should be allowed? •Yes•No•Needs more study•No opinion

Straw poll question #2Regarding the proposal in document 13/994r0 by Peter Ecclesine of Cisco Systemshttps://mentor.ieee.org/802.11/dcn/13/11-13-0994-00-0reg-proposal-for-u-nii-4-devices.docx {additional links?}
Do you believe this proposed band sharing technique has merit and, after developing a more complete definition and field testing, should be considered a basis for a band sharing solution? •Yes•No•Not enough information/needs more study•No opinion

Straw poll question #3Regarding the proposal in document 13/1449r2 by Tevfik Yucek of Qualcomm (and others)https://mentor.ieee.org/802.11/dcn/13/11-13-1449-02-0reg-proposal-for-dsrc-band-coexistence.pptx http://apps.fcc.gov/ecfs/document/view?id=7022418821

Submission
Straw poll question #4
Which proposal do you support for further specification development and field testing?•The 13/994r0 proposal by Ecclesine [1] •The 13/1449r2 proposal by Yucek [1]•I support a combination of both proposals with additional details added•I believe further study of both proposals independently is needed•Neither – I do not support any band sharing•While I support band sharing, I do not believe either approach can form the basis for an acceptable band sharing solution – we need something different
January 2015
Jim Lansford, CSR TechnologySlide 7
Note 1: Both proposals will need additional development before field testing

Submission
Straw poll question #5If it would enhance band sharing, would you support a proposal to move the V2V Safety Channel (currently in Channel 172) to one of the upper channels (180, 182, or 184)? (Note: this could require a rule change)•Yes•No•Not enough information•I don’t support band sharing•No opinion

Straw poll question #6
• Would you support a proposal to use one of the upper channels (180/182/184) for BSM traffic instead of Channel 172? (No rule change. Part 95 still applies to Channel 172. Channel 172 would be shared with Part 15 devices)
• Yes• No• Not enough information• I don’t support band sharing• No opinion

• If band sharing is allowed, would you prefer that the upper edge of the U-NII4 band be at 5.925 GHz (all 75MHz) or 5.895 GHz (only the lower 45MHz)?
• Only lower 45MHz• All 75MHz• No opinion• I do not support band sharing
Lower 45MHzAll 75MHz
Keep/reword the question, or delete it?
doc.: IEEE 802.11-15/0240r0
Submission
Straw poll question #8
• If sharing is only allowed in the lower 45MHz portion of the band (5850-5895MHz), should DSRC only use 20MHz channels in that shared portion of the band? (Note: Channels 172 & 178 in Part 95 are defined as 10MHz in bandwidth, so a rule change may be required)
• Yes – only 20MHz DSRC channels in the shared band• No – DSRC should use 10MHz channels• No opinion• I do not support band sharing

Straw poll question #9
If a Clear Channel Assessment approach is adopted as outlined in document 13/994r0 by Ecclesine, would unlicensed devices need to vacate the entire 5850-5925 MHz band after detecting a DSRC signal on one channel within the band in order for sharing to be feasible?•Yes – unlicensed devices would need to vacate the entire shared band (5850-5925 MHz) after detecting a DSRC signal on one channel•No – unlicensed devices could still operate in other parts of the shared band (5850-5925 MHz) after detecting a DSRC signal on one channel•No opinion•I do not support band sharing
