Abstract
Here, we document the changes to the terminology of the current s draft. This document summarizes the changes that have been applied to the “Word-conversion” of the s draft As it contains the full draft, the latter document must not be uploaded to Thus, we provide an overview of the changes applied.

September 2008
General changes (1)
Change “mesh”, “mesh network” and “WLAN mesh” were meant as “a wireless mesh network based on ” to “Mesh Basic Service Set” or “MBSS”
Use the term “mesh” as adjective
Rational
Base standard (& (approved) amendments) has several kind of STAs
HT STA (802.11n)
QoS STA ( )
Dependent STA (802.11y) …

General changes (2)
Replace all occurrences of MP with mesh STA resp. mesh station
Replace all occurrences of MAP with mesh AP resp. mesh Access Point
Replace all occurrences of MPP with portal
There is no mesh specific portal
Portals connect and non networks
See
Update definition section
Update abbreviation section

5. General changes (3) Use MBSS whenever the whole network is meant

General changes (3)
Use MBSS whenever the whole network is meant
Example:
Mesh Key Distributor becomes  MBSS Key Distributor
Etc.
Form logical groups & give them a name
The MBSS is the set of mesh STAs that cooperate on the formation of the MBSS
A mesh STA is a member of exactly one MBSS

September 2008
Changes to
Renaming
Mesh BSS: The Wireless mesh network
Rational
Two explanatory occurrences of “ Wireless mesh network” before MBSS is introduced
Used as general description
Avoids s specific terminologies before explaining them
Clause introduces the concept of
Mesh Basic Service Set (MBSS)
Groups mesh STAs
Mesh STAs
Are members of an MBSS

Further changes to
New picture
Separate mesh STA
AP is an additional STA service

WDS term – killed …
Delete the term “Wireless Distribution System”
Not useful
Confuses readers
In conflict with s

Mesh ID
Replace “Mesh ID” by “Mesh BSSID”
Cohesive with BSSID
Refer back to base standard

10. Clarify ToDS/FromDS bits
September 2008
doc.: IEEE /1120r1
September 2008
Clarify ToDS/FromDS bits
ToDS and FromDS bits set to 1
“A data frame using the four-address MAC header format. This standard defines procedures for using this combination of field values for the MBSS only. In an MBSS, this bit combination indicates the presence of the Mesh Control information.”
