Key Benefits

Centralized Visibility, Management,
and Control of the Wireless
Environment
The 3Com ® Wireless LAN Mobility system
consists of a 3Com Wireless LAN
Controller (WX4400), 3Com Wireless LAN
Switch (WX1200), and 3Com Wireless LAN
Switch Manager software. The Wireless
LAN system centrally manages and
controls 3Com or third party wireless LAN
Managed Access Points (MAPs). It is ideal
for demanding, complex deployments with
multiple offices or with highly secure LAN
requirements.
Comprehensive Control of MAPs for RF
Optimization and Enhanced Security
Control MAP configuration and optimize
radio-frequency (RF) coverage and
performance using 3Com wireless
controllers and switches, which are all
managed from the 3Com Wireless Switch
Manager, and can be accessed anywhere on
the network. With a few keystrokes, param-
eters can be changed for multiple MAPs,
eliminating the time-consuming task of indi-
vidually configuring each device, and
providing simple setup. The result simplifies
initial deployment as well as easing long-
term management.
Enhanced Control for Seamless
Security and Mobility
Because wireless clients are mobile, 3Com
uses innovative Identity-Based
Networking to deliver network services.
This approach is based on user identity
instead of ports or devices. Multiple
controllers and switches, grouped into a
Mobility Domain share user databases to
support mobility and security across the
entire network infrastructure, including
remote offices.
Through this WLAN-wide information
exchange, the 3Com Wireless LAN
Mobility System enforces consistent
network-wide access and security policies
as users roam the network. No longer
connection-dependent, user location,
security and access details are quickly
transferred between switches and/or
controllers. This enables fast roaming with
seamless security and session integrity
without the need for re-authentication or
IT intervention. Fast roaming with session
integrity also enables interoperability with
voice-over-Wi-Fi phones.
Strong Wireless Security
Implementations and Management
The wireless switching solution builds on
3Com's already strong wireless security
features to fortify network protection.
3Com's existing foundation of wireless
security includes AES, TKIP, and WEP
encryption combined with WPA and
802.1X authentication.
The 3Com Wireless LAN Mobility System
significantly enhances wireless security
with centralized security management.
The exchange of user-based information
within the Mobility Domain adds an
entirely new level of control for user and
group access to network resources. Once
more, sharing user-specific security policies
between WLAN controllers and switches
results in a consistent enforcement of user
and group attributes across the WLAN as
the user roams.
