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.

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.
