If a connection is needed between three separate buildings lets say a,b,c on the same ip subnet ( is that a valid option with vlan tagging?)

and we have to provide roaming between all three buildings considering that a areial will be put on on top of building A to connect building B and C.

will it be a point to point connection from building A to building B and C ?

or will it be a point to multipoint connection as areial on building A will be serving two buildings i.e B and C .

Hi actually i found out it is point to multipoint,

but is it possibe that from one AP bridge( i.e building A ) , only two buildings can be pointed B and C i.e in line of sight respectively , considering that there is one building in between which is not as tall as all a,b and c.

(will they be able to provide roaming? if they are bridged)

Hi Guest:

Long time since your post. Roaming (moving between basic service areas or BSAs) is supported by reassociation which in turn is supported by a common service set identifier (SSID) in the several basic service sets (BSSs). Prompt reassociation while roaming often assumes a common IP subnet, which is what one expects with bridging.

I hope this helps. Can you add your name and location to your forum profile? Thanks /criss
