11 MBPS WIRELESS LAN BUILDING-TO-BUILDING BRIDGE
4
Product Features
Fast data transfer rates Allow bridging speeds much faster than
leased-line service.
Excellent range with antenna options Provide wireless links up to 1300 meters
using omni-directional antennas, and 4100
meters using sector panel antennas.
Point-to-point and point-to-multipoint Lets users transfer information between
support two buildings or multiple buildings across
the campus.
Dynamic rate shifting Keeps network connections available and
reliable by automatically determining
transfer rates based on signal strength and
environmental conditions.
MAC layer encapsulation Ensures LAN protocols are transparent to
the user. Secures data over the wireless link.
40- and 128-bit WEP encryption Allow users to exchange information in
full privacy.
Transparent to VPN protocols Enables encrypted data to pass without
interception.
GUI management interface Helps you to manage all bridges from any-
where on the same subnet—also displays
signal strength monitoring and usage data.
Remote management Allows IT administrators to manage
the bridge remotely, using the Internet
and Telnet.
Firmware upgradeable design Provides convenient local and remote
firmware updates from anywhere on the
same subnet, reducing IT workload and
helping to lower total cost of ownership.
Protocol independent Supports all networking protocols,
including TCP/IP, IPX, and more.
