3Com®Wireless LAN Managed
Access Point AP2750
•3Com’s “fit” Managed Access
Points keep encryption local to
protect network transmissions
•Centralized controls distribute
configurations simply and
securely to MAPs, enabling
savings on management and
operational expenses
•More than a simple access point,
MAPs gather intelligence about
the WLAN through RF scanning
and monitoring

Key Benefits
Strengthens Security Implementations
and Management from Network to
End Users
The 3Com®Wireless LAN Managed Access
Point (MAP) AP2750 augments mobile
security and provides wireless LAN
connectivity for WLAN users. An integral
component of 3Com’s Wireless LAN
Mobility System, the 3Com AP2750
encrypts transmissions to protect data
privacy and responds to commands from
the Wireless LAN Switch WX1200 or the
Wireless LAN Controller WX4400. Because
the AP2750 is fully controlled by a
Wireless LAN Switch or Controller, it
contains no local data-store for sensitive
data, eliminating the vulnerability of user
or network information being compro-
mised due to hacking or theft. The result is
a highly secure access point that reduces
capital expenses and responds to manage-
ment commands to reduce ongoing
administration costs – all while keeping
the wireless LAN secure.
Simplifies Configuration, Control, and
Optimization of MAPs
The arduous process of configuring and
deploying even a few access points is
vastly simplified using 3Com’s AP2750.
The AP2750 utilizes standards-based
integration with the Wireless LAN Switch
WX1200 and Controller WX4400 for
simple plug-and-play installation. There
is no need to pre-configure MAPs, and if
one needs replacing, it automatically
inherits its configuration from the switch
or controller—making it comparable to
changing a light bulb. The configuration
details for all MAPs are centrally distrib-
uted for consistency and accuracy
resulting in simplified initial deployments
as well as easier long-term management.
Automated network controls at the wireless
switch improve MAP coverage and service
by optimizing RF gain, assigning radio
channels, load balancing and even
sweeping the RF environment as required,
either continuously, on-demand, or based
on your schedule.
Provides Security and Seamless Mobility
MAPs provide local traffic encryption
which distributes encryption processing
across the network rather than relying on
one central device. Continuous, on-demand,
or scheduled RF scans can be used not
only to locate users but also to identify
and isolate potentially harmful rogue
access points (APs) or other infiltrators.
3Com wireless switches and controllers
integrate with backend authorization/
authentication/accounting (AAA) servers,
consistently enforcing user and group
access policies across the wireless LAN,
providing secure session integrity as users
roam throughout the network—no reasso-
ciation or IT intervention required.
Eases Network Integration through
Flexible Deployments
Allowing network wiring flexibility, the
AP2750 can be linked directly or indirectly
to a 3Com Wireless LAN Switch or
Controller through existing wired
networks, even across Layer 3 boundaries.
Additionally, the AP2750 can receive its
power via standard PoE (Power over
Ethernet) either directly from a Wireless
LAN Switch WX1200 or from any 802.11af
compliant PoE device.

Key Applications
3Com Wireless LAN Managed Access Point 2750
devices deployed throughout the network can be
located away from their associated wireless
controller or switch. The 3Com SuperStack3
Switch 4400 PWR or 3Com Wireless LAN Switch
WX1200 can supply power and data to the MAPs
over Ethernet cabling.

Description
STANDARDS-BASED, HIGH-SPEED ARCHITECTURE
High-speed wireless performance Supports 802.11 a or b/g for speeds up to 54 Mbps at distances up to 100 meters (328 feet) for 802.11b/g
users, 50 meters or (164 feet) for 802.11a users.
Wi-Fi certified 802.11 a or b/g operation Dual-mode radio allows operation for 802.11a or 802.11b/g and is software configurable from the 3Com
Wireless Switch Manager.
Virtual Access Points Each AP2750 can handle multiple BSSID/SSIDs to appear as multiple access points.
Supports 802.3af-compatible Both data and power are supplied over the same Ethernet cable to the AP2750, eliminating the need for
Power over Ethernet (PoE) power adapters, power cords or AC outlets.
Dual-mode diversity radio antennas Dual-mode 802.11a and 802.11b/g antennas provide excellent performance and coverage in high
multi-path environments.
Dual-mode external antenna options Support a variety of external dual-mode antennas for flexible installing options.
SECURITY
Encryption Performs packet encryption over the air for dynamic WEP, TKIP and AES.
Virtual Private Groups Ability to have independently encrypted and isolated subnets or VLANs while using the same SSID.
RF Multi-band Sweep Any AP2750 can scan the RF environment for both 802.11a and 802.11b/g rogue access points, ad-hoc users
or other RF interferers.
Secure MAPs from theft and hacking There is no local data store of sensitive network information in the MAPs, so if one is stolen no secure
information goes with it.
COMPREHENSIVE MANAGEMENT AND CONTROL
Zero configuration installation No pre-staging or pre-configuration of access points required and replacement MAPs inherit configuration
information from the wireless LAN switch or controller.
Flexible deployment topologies supported MAPs can be direct and/or indirectly connected to their managing wireless LAN switch and/or controller
allowing a wide variety of flexible deployment scenarios.
Automated transmit power and radio Transmit power settings and radio channel assignments can be set to optimize the RF cell size and support
channel assignment international requirements.
Comprehensive MAP control and management MAPs are not operational in stand alone mode. All Attributes such as channel number, power level, SSIDs,
and security settings are all handled by the wireless LAN switch or controller for additional security
