Product Overview
The NWE9251 is a 2.4GHz 802.11g Wireless Outdoor Bridge
that compliant 802.11b/g standards. The NWE9251 covers a
large operating distance for Wireless LANs and broadband
Internet Access with transfer data rate up to 54Mbps. It links
two or more separate networks (typically located in different
buildings) to create a single expanded LAN quickly, simply, and
economically. The NWE9251 delivers higher transmission rates
than an E1 or T1 line, and eliminates the inconvenience of
installing an expensive leased line or fiber-optic cable. The
NWE9251 fully complies with the IEEE802.11b/g standard.
Combining superior wireless technology and advanced
features, the NWE9251 Wireless Outdoor Bridge is a reliable,
high-performance, cost-effective solution for the most
demanding wireless networking environments.
802.11g Wireless Outdoor Bridge

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
