Features, Benefits & Specifications
Secure High-Speed Wired-Wireless Connectivity
Extend the functionality of your network with this universal
Wi-Fi bridge. The bridge enables a laptop or PC user without
built-in wireless capability to connect to a wireless LAN. When
paired with a low-cost 3Com® OfficeConnect® Dual Speed Hub, up
to 16 network devices—PCs, printers, point-of-sale devices, and
Internet appliances—can be connected to a wireless LAN.
Eliminating the need for Wi-Fi PC cards and adapters for each
device creates a mixed wired and wireless network at a much
lower cost while maintaining flexibility as network needs
change.
The wireless LAN workgroup bridge supports all three IEEE 802.11
a, b, and g networking standards. This all-in-one support
preserves existing equipment investments while supporting the
latest higher-speed technologies. Mix and match radio bands to
meet different coverage and bandwidth user needs within the same
area. A one-time configuration at initial setup translates to a
true plug-and-play experience. Once setup is complete, the
bridge can be remotely managed using a standard Web browser or
SNMP management tools. Auto network connect keeps wireless users
connected to the network, even when roaming across IP subnets,
with a choice of ad hoc or infrastructure connectivity mode.
- Economically expands a mixed wired and wireless network
by eliminating the need for wireless PC Cards and adapters
- Enhances the revenue potential of hotel and leisure
business hotspot services by extending WLAN access to laptop
and pocket PC users who dont have built-in wireless
capability
- When paired with the 3Com OfficeConnect Dual Speed Hub
16 (3C16754-US), the bridge can connect up to 16 network
devices to a wireless LAN
- Simultaneous 802.11 a/b/g wireless standard support
delivers comprehensive coverage and investment protection;
Wi-Fi certification ensures broad compatibility
- Advanced 256-bit WPA encryption, and 40/64- and 128-bit
WEP encryption, protect all communications over the wireless
LAN
- 802.1X server authentication with PEAP and EAP-TTLS
protocol support help ensure that only authorized uses
access the network and centralize authentication control and
management
- Simple one-time setup, with no configuration required in
most cases, makes for true plug-and-play operation
- Web browser and SNMP support enable administrators to
remotely manage the bridge from anywhere and seamlessly
integrate the wireless LAN with enterprise management tools
- Optional 2.4/5 GHz dual-band omnidirectional antenna
extends the bridges wireless transmission range and adds
installation flexibility
