Re: Wireless highavailability.... Cisco WLAN solutions

Just a comment ... best to test it out yourself.

Even using WPA and roaming with your laptop, you may not notice any dropped
pings. If the pass codes are the same across all your APs, this
re-authentication process can occur fairly quick and even within the timeout
for a ping. It can re authenticate quickly.

Is this quick enough for voice or your other apps? Too hard to say in an
email ... as Tony says, a site survey is the best.

Suggested to always use a controller, especially for the size you mention.
Too much to add in an email and I have to jump on a call ... but a few
things you gain from a controller that will impact your apps:

DOS protection
Channel and power automation across your APs, reporting for these
Location and protection from rogue APs ...
QoS policy enforcement
Roll out, easier to support, ease of use
blah blah blah ...might be a few more things to add, and I hope the point is
made.

When you invest in a Wifi network the size that you mention, whats the issue
with going all the way and doing it right ...

Whatever you choose, I am sure the super smart folk on this list (I bring
down the average) would love to hear. Take care and good luck!!! HTH,
