Wireless in Subways?

By Stanford Center for Internet and Society on

My friend Shane tells me that Blackberrys work in the NY subways because they run on old radio pager technology.  Apparently, the subways have long had radio transmitters that allow people to be paged while underground, not just in stations.

Is this true?  Also, what happens in Tokyo or Seoul?  Is there wireless data being transmitted--for pagers or phones?
