Point-to-point Mode

Bridges in point-to-point mode
connect two networks in
different locations through a
single wireless link. This allows
two widely separated sites to
share resources, including a
single high-speed connection
to the Internet.

Point-to-multipoint Mode

Bridges in point-to-multipoint
mode connect three or more
networks in scattered buildings
through wireless links. This
allows numerous sites in a
wide area to share resources,
including a single high-speed
connection to the Internet
