OVERVIEW

The 3Com

54 Mbps Wireless LAN Building-to-

Building Bridge provides IEEE 802.11a

and 802.11g

Wi-Fi

connections and bridged links across building

complexes, enterprise campuses and metropolitan

areas. Wireless outdoor bridges can connect intra-

building LANs which are up to 10 miles (17 kilometers).

In addition, the 3Com 11a 54 Mbps Wireless LAN

Outdoor Building-to-Building Bridge and 11b/g Access

Point combines the functions of a bridge and a full-

featured wireless access point in one durable

weatherproof unit.

By installing 3Com building-to-building bridges,

enterprises can avoid the expense of extending their

cabling plant between buildings or using expensive

leased lines with recurring monthly service fees.

Rugged design and multiple security features help

ensure continuous, reliable and secure operation.

Several antenna options are available for the indoor

bridges and the outdoor bridge/access point.

KEY BENEFITS

NETWORK CONNECTIONS EVERYWHERE

3Com building-to-building bridges let users connect

to the enterprise network at full 54 Mbps or 108 Mbps

Wi-Fi speeds wherever they happen to be working—

even outdoors or in a remote facility across town.

Extending the network beyond the reach of Ethernet

cabling gives users more freedom and helps them be

more productive. The bridges support both point-to-

multipoint and point-to-point operation to meet a

variety of configuration requirements.

BRIDGE AND ACCESS POINT COMBINATION

The 3Com 11a/11g Outdoor Building-to-Building

Bridge and Access Point provides point-to-point or

point-to-multipoint bridge functionality while

simultaneously using another band for access point

operation, providing connectivity for mobile users. The

access point, repeater, or bridge functionality can be

independently configured on both radios, making the

product extremely flexible for a variety of applications.

The bridge function supports data rates up to 108

Mbps between buildings or to offsite locations. The

access point function provides connectivity at up to

108 Mbps for as many as 128 users.

With access point and bridging functionality on the

same unit, mobile users can link to the network and

the traffic can be backhauled over a wireless point-to-

point or point-to-multipoint bridge link to another unit

attached to the wired network up to 15.5 kilometers

(9.6 miles) away. The unit includes an embedded 17

dBi high-gain antenna for bridging applications.

Optional external omni-directional and directional

antennas are available separately.

3COM 54 MBPS WIRELESS LAN BUILDING-TO-BUILDING BRIDGE AND ACCESS POINT KEY BENEFITS (continued) WIRELESS COST ADVANTAGES Using wireless bridges to extend the network saves the high cost of installing cable between buildings. Enterprises can also avoid the expense of leasing T1/E1 lines, which can cost up to US $1,000 per month or more. And 3Com building-to-building bridges provide 10 to 20 times the bandwidth of T1/E1 lines.
