RE: Meeting Survey Results

Jordi,

With the RF characteristics of 802.11b/g (including the fact that
there are only three non-overlapping channels (in the US) and they all
exist in the already overcrowded 2.4 GHz freq range) and the density
of users in the meeting rooms at the IETF, you cannot "warrantee" 
a level of performance. I attend both IEEE 802 and IETF meetings and 
both struggle with wireless coverage at those densities for this 
very basic physical reason. The more transmitters you have 
transmitting on the same frequencies in the same space, the more noise 
you will have. The more noise you have the more performance issues
you will experience. Technology and product evolution will improve
the situation, but we have to work with what we have. 

While 802.11a hasn't overtaken 802.11b/g in general, it is much 
better suited for our environment. There are more non-overlapping 
channels, it operates in the less crowded 5 GHz range, and the 
range is shorter. Thus you can deploy more APs in the same space 
without contributing to the overall noise issue.  

We are suggesting that users that are willing and able should
consider investing in 802.11a cards for a happier IETF network
experience.  Anything we can do to reduce the level of noise at
will make the experience better for the remaining users. 

Past and current NOC teams plan to deploy the best network they 
can with the resources available. Donations of equipment and
expertise are always welcome.

Hi Jonne,

I'm not sure if I got it. My MUST was on the other way 
around: We really
need to warrantee good coverage for b/g to 75% of the participants.

Hi Jordi,

the preference for .11a was stated because we want to make sure that
everybody who has the possibility for it would use it. It makes the
network much more reliable. Of course b and g are provided as well.

It is a recommendation not a MUST, like the mail says.

Cheers,

Jonne.

Hi Ray,

I'm not sure if we need some clarification on this:

1.  Slightly more than 25% say their laptop is compatible

with 802.11a.

[Note the IETF 65 NOC for Dallas recommends 802.11a]


According to the survey, only 25.5% of the participants

have 802.11a, which

in my opinion means that 11b/g MUST be reliable for 75% of

the participants

in the next meeting.

Remember that if we don't have an 802.11a interface in our

laptops is

because *THEY DONT'T HAVE IT*.

In my own case, having a Mac is not easy to get built-in

802.11a. I can of

course buy an external card, but is not reasonable (more

power consumption,

more things to carry, etc.). There is one more reason, is

that in most of

the world is not (today) widely used, so buying it almost

only for IETF

meetings, don't make too much sense.

Even do, if it is just me, I will consider buying it, but

I don't really

agree to get this asked for 75% of the participants. It is

not a choice !


So the clarification is ... what we actually will get at

IETF65, and if

something must be changed now for getting good 802.11b/g

support, please,

make sure about that now !

Regards,
Jordi

Asunto: Meeting Survey Results

All;

More than 300 responded to the Meeting Survey conducted

following IETF 64

in Vancouver.

See survey results link below.

Among the results are:
1.  Slightly more than 25% say their laptop is compatible

with 802.11a.

[Note the IETF 65 NOC for Dallas recommends 802.11a]

2.  Nearly 60% (with an additional 23% undecided) prefer

dinner following

all sessions of the day.

3.  Only 23% prefer a full day schedule for Fridays.

4.  Cookies are not the only craving for breaks -- 74%

want more healthy

choices.

5.  Only 1/3 of the respondents expressed satisfaction

with the wireless

connectivity.

And given the opportunity to say what they liked and

didn't - 130 told us

how they felt.

Read it for yourselves:
http://www.surveymonkey.com/Report.asp?U=165657447306

I and NeuStar Secretariat Services will review these

results and make

adjustments as possible for IETF 65 Dallas, March 19 -

24.  And we look

forward to seeing you there.

Thanks for your participation.

Ray Pelletier
IETF Administrative Director.
