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

®

11g 54Mbps

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. 

Reliable Connections

Dynamic rate shifting helps keep network

connections available.

Multiple Security Features

To shield wireless communications, WPA-

PSK and AES authentication and

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.

Description

FLEXIBLE HIGH-SPEED CONNECTIVITY

Economical wireless building-to-building links

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. 

High-speed 54Mbps data rate

Delivers 10 to 20 times the throughput of expensive T1/E1 lines through secure wireless network 

connections; easily handles large multimedia file transfers. 

802.11g standard

Supports latest high-speed data transfer rates—five times the speed of 11b networks.

Antenna choices (Indoor Building-to-Building 

Antenna and cables are required; choose from 4dBi to 18dBi panel or omni-directional antennas for 

Bridge)

maximum RF coverage for a wide range of applications.
