VoWLAN Roaming without WLAN Controller (WLC)

[ee_fauzan189]

Hi,

Need some advice here. I am trying to implement VoWLAN in a company using Cisco WAP4410n Access Point. The problem is, I've downloaded all Cisco WLAN Controller (WLC) data sheets and can't find any compatible WLAN Controller for this type of Access Point.

Can I still implement VoWLAN without WLAN Controller? Is there any way to provide smooth intercell roaming without WLAN Controller?

Thanks

WLC does NOT support AP4410n.

Just make sure you have 20% intersection of the signal.

Thanks leolaohoo,

Without WLC, do users need to re-authenticate and renew their IP address during intercell roaming? Will it interrupt (drop) the call?

Thanks

Depends on alot of stuff.

Do you have 20% channel overlap?

What radio is being used?

How dense is the deployment?

I have designed the cells so they have 20% cells overlap. I've also designed the channels so they won't interfere with each other (I use 2 GHz channel here)

But what could be used to replace WLC's role to manage these Access Points? maybe some kind of server?
