IEEE 802.21
Comments on 802.11aq PAR and 5C
21-12-068-00-0000-802.11aq_PAR_5C_Comments.ppt
PAR- Section 5.2.b
• 5.2.b. Scope of the Project: “This amendment
defines modifications to the IEEE 802.11 standard,
above the physical layer (PHY), …”
• Comment: Does this mean it could be done at a
layer higher than MAC layer? Would suggest to
revise the scope as follows:
“This amendment defines modifications to the IEEE
802.11 standard, at the MAC layer, ….”

PAR- Section 5.2.b
• 5.2.b. Scope of the Project: “ .. enable delivery of
pre-association service information discovery by
IEEE 802.11 stations (STAs).”
• Comment#1: ‘delivery of pre-association service
information discovery’ is a bit confusing. Suggest to
delete the word discovery after information.
• Comment#2 : Will ‘pre-association service
information’ be delivered securely? If not, it should
state that this information will be provided in
unprotected manner.

PAR- Section 5. 4
• 5.4 Purpose: “This standard also offers
regulatory bodies a means of standardizing
access to one or more frequency bands for
the purpose of local area communication”
• Comment: The above sentence is not at all
understandable.

PAR- Section 5.5
• Need for the Project: “This amendment would look at
basic advertising approaches for services .....”
• Comment#1: What are “basic advertising
approaches”? Need some clarity here.
• Comment #2: Do not understand why amendment
would look at approaches rather than providing a
solution.

5C – a) Broad sets of applicability
• Broad sets of applicability: “With the growth of
WLAN technology, discovery will become an
increasingly larger issue in public ….”
• Comment: Not clear what type of discovery is
mentioned here? Need to be a bit more explicit
describing the type of discovery. The PAR mentions
only discovery of services.
Slide 6
21-12-068-00-0000-802.11aq_PAR_5C_Comments.ppt
5C – a) Broad Sets of applicability
• a) Broad sets of applicability: “A pre-association
discovery mechanism will increase the range of
services and market reach of IEEE 802.11 devices”.
• Comment: ‘discovery mechanism’ is a broad generic
term. It should mention discovery mechanism of what
information. For example, “discovery mechanism on
information related to......”

5C – b) Multiple vendors and numerous
users
• b) Multiple vendors and numerous users: “They
perceive the need to standardize a pre-association
discovery mechanism for IEEE 802.11 devices.”
• Comment: Again ‘discovery mechanism’ is a broad
generic term. It should mention discovery mechanism
of what information. For example, “discovery
mechanism on information related to......”

5C – Technical Feasibility
• b) Proven technology, reasonable testing: “All of the
end components of the technology are in use today,
although the pre-association discovery mechanism has
not been developed yet. ”
• Comment: Is the above statement correct? Preassociation network discovery mechanism exists
today. Suggest to change “the pre-association
discovery mechanism” as “the pre-association service
discovery mechanism”
