Revision number of document 109
It appears revision 2 of is based on revision 0, but revision 1 exists.
The latest revision should be used to update a document to make it easier to follow the changes and avoid any confusion.
Some memos are in Japanese. It would be appreciated if English is used in official documents.
Pages 8, 9, etc., of 109r2.

Sub-clause 4.2 Ticket gates
A definition of “initial setup” is necessary.
(Example) What’s included: after discovery or detection?, sync?, etc.
Sub-clause 4.3 Wireless data storage
ETRI will prepare some text for sub-clause 4.3.
Sub-clause
Sub-clause was Discovery.
Question: Don’t we need a sub-clause for discovery in this document? (No strong opinion. Just a question)

Sub-clause Security
Close proximity P2P systems are harder to exploit, but there exist reports/studies showing it is not impossible.
15.3e may not want to eliminate any possible future proposals on security.
Proposed alternative text: “Because of the limitation of the transmission range, lighter security mechanism for the PHY and MAC layers can be used for a close proximity P2P system.”

Sub-clause Power management
Toll gate and kiosk may not require power management, but Wireless data storage requires power management.
Recommendation: Delete the last sentence “No special power management schemes are required.”

Clause 7 Evaluation criteria
The text (“All the requirements and conditions … evaluated as a valid submission.”) doesn’t seem to belong here.
To ETRI’s understanding, “Evaluation criteria” is about how to compare the performance of two competing schemes.
The current text is about the technical scope of submissions.
Recommendation: Move the current text to an appropriate location within Clause 2 General guidelines.
Evaluation criteria are very important. Depending on which criteria are used, scheme A can perform better than scheme B or it could be the other way around.
