I completely agree with your comments about the limitations. We also
have special-purpose WLANs. As Phil mentions, the WLAN override design
is seriously flawed. We approached Cisco last year about this issue and
we requested that it be redesigned. But I don't see it changing any time
soon.

What kind of signal strength, throughput, and other metric values does
everyone use when designing wireless coverage for voice support on
802.11b/g? We might be rolling out voice over wireless soon and I'd
like to do some site surveys to make sure our wireless coverage is
adequate. Are there any
We now do our site surveys with an Iphone (or Itouch)

Iphone/Itouch have a lesser RX sensitivity than almost all laptop
radio's - a simple function the available real-estate for antenna
placement and design. This discrepancy can be as much as 3dB.
If your using these devices to purely take the worst-case scenario -
then good. If not - then you're
Probably stating the obvious- but the iPhone doesn't give you the 11a
view either...

In addition - even the purpose built VoWi-Fi handsets (Polycom, Cisco,
etc.) are physically larger that iphone and much time is spent designing
antenna's to improve their functionality and RX sensitivity.

Ok, let's explain better the behind the scenes of the decision
to answer both questions:
We are designing coverage with the following criteria:
-b/g everywhere with PDA/Iphone in mind
(we already have 250 Iphones registered on campus, if there is one device
that will take advantage of
If your using these devices to purely take the worst-case scenario -
then good. If not - then you're not getting a clear picture of the
typical user experience.
People don't generally walk around with laptops.
Iphone users do.
That's the picture!

Bottom line - the Iphone radio set is not superior - if you plan for
Iphone usage - then you're in better shape if rolling out an enterprise
Vo-WiFi solution with purpose built Wi-Fi handsets.

Stop thinking like an enterprise, and you'll understand Apple products

Guys -
Quite frankly - I am just gitty that there is a discussion on here that
does not revolve around the configuration, debug, and hair pulling of
Cisco WLAN.
For a while there - I though this the Educause Cisco Wireless-LAN
discussion board.
Just a breath of fresh air :)

I agree, this is a great discussion since we don't own any Cisco
wireless equipment. I'm glad I was able to spark such a lively
discussion.
Could you give a little more detail on what you look for when you do
your iPhone site surveys?
Thanks,
Nathan

I hear you -- but I really appreciate hearing everyone gripe (and it is an
issues forum after all).
So how do we go about getting Cisco to hear all this good stuff?
Cisco are you listening?

Of course, that whole discussion by itself might help other vendors and
products look that much better ;-)

Actually, Cisco people can definitely respond to technical questions
on this forum if a question is being asked directly. Educause welcomes
those inputs.
But no sales pitch, vendor comparaison, OR VENDOR OPINIONS!

Many vendors listen to the list as an education, or to contact users
privately (annoying, but hard to prevent).
Some have been burned in the past by Educause's AUP, so they don't
respond anymore.
Ask a direct question they might answer
(you might have to rub the lamp, though ;-)

Thanks Philippe,
I really appreciate this forum and its contributors.Specific questions ,
answers, and observations are very useful, and certainly make me feel less

We are looking to do some dorms wile the students are away and wanted to get
some input on what other folks use as a planner tool for wireless. Any
feature that people like or dislike that we should or should not consider?
Cost is also a factor. Brian

Today, we still do the survey with two devices. A PC with a survey
tool, AND an Iphone. We do the survey with the PC and double check with
the Iphone that we get 3 bars. Since we overcover a little
