2. The road ahead Change log:
September 2008
The road ahead
Change log:
Denver meeting: VHTL6 PAR ( vht) approved by EC
Next steps: prepare the task group work/agenda
NESCOM PAR feedback (See preliminary comments)
Scheduled for consideration during September 25, 2008 NESCOM meeting
Updated by NESCOM (no action required from study group)
Chair designation/election (November meeting)
Prepare founding documents of the task group
Complete usage models
Specify functional requirements
Propose comparison criteria to evaluate the proposals
Review and enhance channel models
Work on a selection procedure
Propose draft timeline for standard elaboration (e.g. call for proposals etc.)

3. Documents of reference and identified limitations
September 2008
Documents of reference and identified limitations
Proposed methodology: reuse what is already available and complement existing documents on new unique additions specific to 11vht
Usage models:
Documents to take into consideration
11n usage models n
Eldad’s review of 11n usage models vht
WFA usage models
First attempt to map usage models to operating bands (6/60GHz) vht
Potential additions/suggestions:
Complement with multi-user usage models (peer to peer, multiple lower rate devices etc.)
Overlapping of usage models between <6GHz and 60GHz operation suggests that a joint document with VHT60 could be worked out
Functional requirements
Example: 11n functional requirements n
Comparison criteria
Example: 11n comparison criteria n
Channel models
Example: 11n channel models n
Remark: current channel models are limited to 100MHz bandwidth, >80MHz operation will require larger bandwidth models to take into consideration RF impairments simulation (160, 320MHz)
Selection procedure
Example: 11n selection procedure
Suggestion towards an improved proposal development process vht
Proposal: review other groups way of conducting business (e.g. 16m) and evaluate split vs. full proposal approaches

Preliminary NESCOM Comments (1 of 2)
5.2 Scope:
The scope of this project is to define an amendment that shall define standardized modifications to both the physical layers (PHY) and the Medium Access Control Layer (MAC)
Why not simplify say: This amendment shall define standardized modifications to both the physical layers (PHY) and the Medium Access Control Layer (MAC)
The scope on the PAR should appear exactly as it will appear in the published standard.
Suggest changing 1st sentence to “This amendment defines standardized modifications to both the physical layers (PHY)…”
5.4 Purpose:
If the standard will have a Purpose clause, it should appear on the PAR exactly as it will appear in the published standard.
If the standard will contain a purpose clause, suggest changing “project” to “amendment” in the 1st sentence.

5.2 Scope: Change to read as it will for the final document –
This amendment defines standardized modifications to both the physical layers (PHY) and the Medium Access Control Layer (MAC) that enable modes of operation capable of supporting:
A maximum multi-station (STA) throughput (measured at the MAC data service access point), of at least 1 Gbps and a maximum single link throughput (measured at the MAC data service access point), of at least 500 Mbps.
Below 6 GHz carrier frequency operation excluding 2.4 GHz operation while ensuring backward compatibility and coexistence with legacy IEEE devices in the 5 GHz unlicensed band.
Missing "and" in 5.6 Stakeholders list
The purpose of the amendment should be stated rather than the project (TG). Change to:
The purpose of this amendment is to improve the wireless local area network (LAN) user experience by providing significantly higher basic service set (BSS) throughput for existing WLAN application areas and to enable new market segments for operation below 6 GHz including distribution of multiple multimedia/data streams.

6. Action points
Identify one coordinator per key document (FR, CC, etc.) for stimulating contributions to generate a VHTL6 specific version.
Prepare drafts of calls for contributions and proposals for consideration in November.
Prepare agenda for November and determine amount of session time required.
Solicit candidates for leadership positions: Chair, Vice Chair, Secretary and Technical Editor. …
