WIFI Roaming within different l2 domains?

hi there,

first of all “happy new year to any reader!”

my requirement for WIFI roaming as following:
i wanna setup severel AP´s with user access on 2/5 GHz on a length of 30 km..
so l2-domains are no really my preffered option.

what kind of setup you would suggest me for an more or less interruptfree roaming?

i would like setup different ipv4 allocationpools per dhcp on one of the 70 AP´s..

did someone solve such a huge option?

or do ou just simple recommend me MESH? (mesh is l2 based i actually wanna avoid..)

just wondering if MT supports in the meantime 802.11f|r ?

thanks for any great answers!

chris

any suggestions?

thanks

chris
