Product Overview

The NWH9250 is a 2.4GHz 802.11g Wireless Outdoor Bridge
that compliant 802.11b/g standards. The NWH9250 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 NWH9250 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
NWH9250 fully complies with the IEEE802.11b/g standard.
Combining superior wireless technology and advanced
features, the NWH9250 Wireless Outdoor Bridge is a reliable,
high-performance, cost-effective solution for the most
demanding wireless networking environments.

Power Over Ethernet

Allows administrators to manage the bridge from anywhere on
the network. All that is required is that the bridge be on the
same logical IP subnet as the management station.

WEP (Wired Equivalent Privacy): 64, 128 and 256-bit WEP
encryption for secure wireless LAN data transmissions.

The detachable antenna design allows such options as
connecting a high-gain antenna for better signal quality over a
wider coverage area.

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
