DATA SHEET
Key Benefits
Flexible, Cost-Effective Extended Reach
Avoid fiber cable installation costs and
headaches—or monthly T1/E1 line
expenses that can total up to US$1,000 per
month for little more than 1Mbps of band-
width. Now you can connect LANs over
secure, high-speed wireless, bridge-to-
bridge links. The 3Com
Wireless LAN Outdoor Building-to-
Building Bridge with integrated 18dBi
high-gain panel antenna is designed to
operate in harsh environmental conditions
at distances up to 10 miles (17 kilometers),
while the 3Com 11g 54Mbps Wireless LAN
Indoor Building-to-Building Bridge works
well in large, open interiors or adjacent
buildings. Deployed together, the bridges
are an intelligent choice for connecting
®
building LANs in campus-like settings.
Standards-Based, High-Speed
Performance
Both 11g 54Mbps bridges deliver ten to
twenty times the bandwidth of T1/E1 links
through secure wireless network connec-
tions and support up to 1000 clients. The
building-to-building bridges can operate in
either point-to-point or point-to-multipoint
configurations to meet growth and specific
application demands.
Description
Brings rapid return-on-investment in as little as 2 to 3 months by eliminating fiber cable installation or recurring
T1/E1 line costs, which can total up to $US 1,000 per month for little more than 1Mbps of bandwidth.
Wireless building-to-building bridge deployments cost about one tenth that of fiber cabling installations and
avoid right-of-way and trenching problems.
Delivers 10 to 20 times the throughput of expensive T1/E1 lines through secure wireless network
connections; easily handles large multimedia file transfers.
Supports latest high-speed data transfer rates—five times the speed of 11b networks.
Antenna and cables are required; choose from 4dBi to 18dBi panel or omni-directional antennas for
maximum RF coverage for a wide range of applications.
Reliable Connections
Dynamic rate shifting helps keep network
connections available.
Multiple Security Features
To shield wireless communications, WPA-
PSK and AES authentication and
®
11g 54Mbps
encryption provide the latest industry-
standard security. VPN and VLAN support
keep network data private and transmissions
safe from security breaches.
Simple Installation and Management
Setup wizard software makes installation
and configuration easy. Once setup is
complete, the building-to-building bridges
can be remotely managed using a standard
Web browser or SNMP management tools.
