DATA SHEET
OVERVIEW
3Com®wireless LAN Managed Access Points (MAPs) deliver secure,
reliable connectivity for WLAN users. An integral component of the
3Com Wireless LAN Mobility System, the 3Com MAP 3750, MAP 3150
and MAP 2750 encrypt transmissions to protect data privacy. Fully
controlled by a WLAN switch or controller, they contain no local data
store for sensitive data, eliminating the chance of information being
compromised due to hacking or theft. The end result helps reduce
capital expenses and ongoing administrative costs—all while keeping
the wireless LAN secure.
KEY BENEFI S
SIMPLIFY CONFIGURA ION, CON ROL AND OP IMIZA ION
With remote management, the arduous process of initially configuring
and deploying access points (APs) is vastly simplified because configuration
settings are centrally distributed for consistency and accuracy. And for
easier long-term management, any added MAPs inherit configuration
settings from their wireless switch or controller. Automated network
controls at the wireless switch improve MAP coverage and service by
optimizing RF gain, assigning radio channels, balancing traffic loads and
monitoring the RF environment.
DELIVER SECURI Y AND SEAMLESS MOBILI Y
Local traffic encryption distributes the encryption processing across
the network rather than relying on one central device. Continuous, on-
demand, or scheduled RF scans can be used to locate users and identify
and isolate potentially harmful rogue APs or other vulnerabilities. 3Com
wireless switches and controllers integrate with backend Authorization/
Authentication/Accounting (AAA) servers, consistently enforcing user
and group access policies across the wireless LAN to provide secure ses-
sion integrity as users roam throughout the network. No re-association
or IT intervention is required.
EASE NE WORK IN EGRA ION HROUGH FLEXIBLE
DEPLOYMEN S
For operational flexibility, the MAP 2750, 3150 and 3750 can be linked
directly or indirectly to a 3Com WLAN switch or controller through
existing wired networks, even across Layer 3 boundaries. For additional
installation flexibility, the 3Com WLAN switch can also supply the MAPs
with power, as well as data, directly over standard Ethernet cabling.
The MAP 3150 and 3750 support both IEEE 802.11a and 802.11g users
simultaneously; administrators can mix and match radio bands to meet
different coverage and bandwidth needs.

KEY BENEFI S
(CON INUED)
FEA URES
BOOS RELIABILI Y AND RESILIENCY
The MAP 3750 offers dual Ethernet ports with Power over Ethernet
(PoE) support. With automatic failover capability for both data and
electrical power, the MAP 3750 adds a level of redundancy for
demanding environments and increases network uptime.
S ANDARDS-BASED, HIGH-SPEED ARCHI EC URE
Dual-band operation
› The software-configurable dual-mode radio on
the MA 2750 operates in 802.11a or 802.11b/g bands. The MA 3150 and
3750 radios supports IEEE 802.11a and 802.11b/g simultaneously for user
flexibility.
High-speed wireless performance › IEEE 802.11a offers speeds up to
54 Mbps at distances up to 50 meters (164 feet); IEEE 802.11g offers speeds
up to 54 Mbps at distances up to 100 meters (328 feet).
Diversity radio antennas › For excellent performance and coverage in
high multi-path environments, the MA 2750 and 3150 ship with external
dual-band omnidirectional antennas; the MA 3750 has integrated
(internal) omnidirectional antennas.
SECURI Y
Strong, multiple encryption › IEEE 802.11i W A2 Advanced Encryption
Standard (AES), W A dynamic Temporal Key Integrity rotocol (TKI ) and
Wi-Fi Equivalent rivacy (WE ) packet encryption help ensure strong data
security.
Virtual private group support › Administrators can independently
encrypt and isolate subnets or VLANs using the same SSID.
RF multi-band sweeps › Scans of the RF environment search for rogue
access points, ad-hoc users and sources of RF interference.
heft- and hacker-safe › No local data store of sensitive network data
means that if a MA is stolen, no secure information goes with it.
INS ALLA ION EASE AND FLEXIBILI Y
Simple installation
› No pre-staging or pre-configuration is required for
new MA S; replacement MA s inherit configuration information from
their WLAN switch or controller.
Flexible deployment topologies › MA s can be directly and/or remotely
connected to their WLAN switch and/or controller, offering a wide variety
of flexible deployment scenarios.
PoE support › Both data and power are supplied by a 3Com wireless
switch or any 802.11af-compliant device over Ethernet cabling, eliminating
the need for power adapters, power cords, or AC outlets.
Dual-mode external antenna options › A variety of external dual-mode
antennas are supported for flexible installing options.
RESILIENCY
PoE and data port redundancy › If the MA loses either the LAN or oE
connection on either port, it will automatically failover to the other port,
increasing network uptime (MA 3750 only).
COMPREHENSIVE MANAGEMEN AND CON ROL
Automated transmit power and radio channel assignment
›
Transmit power settings and radio channel assignments can be set to
optimize the RF cell size and to support international requirements.
Remote management › Channel number, power level, SSIDs and secu-
rity settings are all handled by the wireless LAN switch or controller for
additional security; MA s are not operational in stand-alone mode.
