Al, Kevin,
Enclosed is a text document containing a brief synopsys of the work to date
in the IEEE 802.11T (wireless metrics and methodologies) task group. I've
included the relevant metrics and methodology presentations and formal draft
text contributions, which should give interested BMWG members a good
understanding of what's going into the IEEE 802.11T draft at the moment.
If it passes muster, I can post it to the BMWG reflector. Alternatively you
could post it, or speak from it at the upcoming IETF meeting in Paris.
Thanks!

Brief Update on IEEE 802.11T (Wireless Performance Task Group) Activities
-------------------------------------------------------------------------
The 802.11T task group has met twice since the Minneapolis IETF meeting;
during May 2005 in Cairns, Australia, and again during July in San Francisco,
CA. A draft document has been started and proposals for definitions, metrics
and methodologies are being accepted and incorporated into the draft. The
draft document is quite limited at present (no metrics, some definitions,
and one test environment methodology) but is making progress.
The meeting in San Francisco was fairly productive. A total of five proposals
for metrics and methodologies were made, covering conducted (cabled) testing,
over-the-air (open-air) testing, Adjacent Channel Interference rejection
measurement, BSS transition time (roaming) measurement, and link layer metrics
tests. Of these, two proposals were accepted for inclusion into the draft;
the authors of the remaining three were requested to update and augment their
proposals and bring them back for consideration at the next meeting in
September. Additional presentations were also given.
The two accepted proposals were on conducted testing (IEEE 802.11 document
number 11-05-0660/r0) and over-the-air testing (document number 11-05-
712/r0). In addition to the proposed draft text, the authors submitted
PowerPoint presentations (document numbers 11-05-0661/r0 and 11-05-0711/r0,
respectively) describing their approach, test setup, and experimental
results.
The technical editor (Tom Alexander) is presently working on incorporating
the two accepted proposals into the draft. With the inclusion of these
proposals, the draft will reach version 0.3, and is estimated to be about
40 pages long.
The next meeting will be in Garden Grove, Orange County, California, from
September 18th to 23rd. For additional information, see http://ieee802.facetoface-events.com/wireless/.
A list of relevant presentations and draft text proposals have been provided
below, as well as instructions on how to obtain them from the IEEE 802.11
document server. The IEEE 802.11 process is to incorporate voted-in draft
text proposals into an evolving draft with only editorial changes. Hence the
technical substance of the current draft can be understood by looking at
these contributions.

Procedure For Access To IEEE 802.11T Documents
----------------------------------------------
1. Navigate to http://www.802wirelessworld.com
2. In the top right, it will say: "Welcome Guest! Please login or register".
Click on "register".
3. This will take you to a page requesting an e-mail address (which will
also serve as a login ID) and a password of your choice. Type in your
e-mail address and a desired password. Any valid e-mail should be
acceptable.
4. Once your e-mail and password have been accepted, the system will request
you to actually log in using this information. Log in as directed.
5. The system will now take you to a contact update page. Type in your
contact information.
6. After entering your contact info, the system will ask you to select a
group of interest. Click on "802.11 WLAN WG" (and any other groups you
might be interested in).
7. You will now be shown a meeting attendance, voting status credit, and
WG information access web page. Click on "802.11 WLAN WG" under "Working
Groups" in the column on the left to expand the choices for the
802.11 WG.
8. Select "Documents" under "802.11 WLAN WG". This will bring up a WG
document listing. Be sure that the tab "Document Listing" is highlighted,
not "Document Control Numbers". If necessary click on the tab to
highlight it.
9. Documents are displayed in a 3-column format: date/time of submission,
the Document Control Number (DCN), and the document title assigned by
the author. The default sort order for the documents is by date and time
of submission. Pulldowns are available to sort by DCN or by title, and
to reverse the order of sort. Typically the easiest method is to leave
the documents sorted by date.
10. Document control numbers have a structured format of the form:
gg-yy-nnnn-rr-tttt
where
gg = 802 group suffix, in this case "11" for 802.11
yy = last 2 digits of year ("05" for 2005)
nnnn = document number, 1 - 9999, assigned by system
rr = revision number (starting at 00)
tttt = Task Group suffix; TGT's suffix is "000t"
11. Scroll down the table of results using the line at the bottom of the
table (the line:
"Results: 1-25 26-50 51-75 76-100 101-125 Next » Last(4616)")
You will have to manually navigate until you find the document you want.
12. Clicking on the document number brings up a dialog box to allow you to
save it to your computer.
13. No search facility is unfortunately available via the web interface.
This is being remedied but it appears that it will take quite some time
to complete.
14. The bottom of the table displays an FTP host, login and password that
purports to give you access to the same 802.11 documents, but on an
FTP server instead. However, be warned that many of the documents shown
on the document server web pages do not seem to be present on the FTP
server. (For some inexplicable reason the FTP server appears to hold
a subset of the documents accessible via the web interface.)
