To detect AP remotely

I am searching for a way that a systems administrator can
locate/detect/identify unauthorized wireless access points in global (or
WAN) network, including those across the oceans, even not being physically
there!

One way is "war driving". However, it requires a person physically walking
inside the organization or driving around the organization's campus with a
"war driving" software.

Can one use a packet sniffer to find out APs? But it may be "blocked" by
VLANs.

Any advice / pointers are appreciated.

Thanks and have a nice weekend.

Probably a WLAN switch that does Rogue detection, there are ones
for brand office sizes up to corporate. I would suggest having one at
each
remote location. One such switch is Bluesocket but there are others.
There are also APs that work in WLAN monitor mode and do nothng but
monitor the airwaves. Just search google for "Rogue detection": and Im
sure you
will find more that you ever wanted to know.
