3Com® 11a/b/g Wireless LAN Workgroup Bridge
DATA SHEET
Secure and reliable
wireless connections
that extend the
network
OVERVIEW
Extend the functionality of your network with the 3Com® 11a/b/g
Wireless LAN Workgroup Bridge. The bridge provides LAN-to-LAN
secure wireless connectivity for remote LAN segments or devices,
creating a mixed wired and wireless network at a much lower cost while
maintaining flexibility as business needs and network designs change.
KEY BENEFITS
SECURE NETWORK CONNECTIONS
The 3Com 11a/b/g Wireless LAN Workgroup Bridge supports WPA/WPA2
and AES, providing the latest industry standard security; WEP support
provides compatibility with legacy wireless networks. IEEE 802.1X
server authentication helps protects against unauthorized network
access. The bridge allows up to 16 devices to be securely connected
through it to the network.
WI-FI 802.11 A/B/G SUPPORT
The wireless bridge supports IEEE 802.11 a (5.1 GHz) and b/g (2.4 GHz)
networking standards. This preserves existing wireless equipment
investments while supporting the latest higher-speed technologies.
WIFI-ENABLE LEGACY DEVICES
Use the embedded serial port to connect various devices—cash registers,
deli and vegetable scales, time clocks, bar code readers, and more—to
the wireless network, without the costly burden of retrofitting existing
equipment or running extra cabling. This workgroup bridge may also
be used as a wireless terminal server.
CONVENIENT INSTALLATION AND MANAGEMENT
Setup wizard software makes installation and configuration easy. Once
setup is complete, the bridges can be remotely managed using a standard
web browser, CLI or SNMP management tools.

Provides bandwidth and performance necessary for multi-media applications.
OPEN AND FLEXIBLE
Wi-Fi CERTIFIED a/b/g
Ensures bridge interoperability with other Wi-Fi certified products.
Antenna choices
Includes internal dual-diversity antennas. Optional external dual-band antenna extends the wireless
transmission range and adds installation flexibility.
Serial port
Avoid expensive upgrades or retrofitting of legacy products such as cash registers, deli and vegetable scales, time
clocks, bar code readers, etc. by connecting to the wireless network via the serial port of the bridge. Serial port
can also be used for bridge management functions. Workgroup bridge can function as wireless terminal server.
SECURE AND RELIABLE
WPA/TKIP and WPA2/AES; WEP
Toughest industry-standard algorithms help keep wireless transmissions private. WEP support provides
compatibility with legacy wireless networks.
IEEE 802.1X authentication
Provides LAN client and wireless authentication, so that only authorized users access the network.
INSTALLATION AND MANAGEMENT CONVENIENCE
Setup wizard
Simplifies setup procedures.
Web browser, SNMP and
3Com Network Director support
Bridge is easily managed through a variety of interfaces and can be effortlessly integrated with existing network
management tools.
