POWERFUL

High-speed and wide coverage

11g radio supports speeds up to 54 Mbps at distances up to 100 meters (328 feet); 11a radio supports
speeds up to 54 Mbps at distances up to 50 meters (164 feet); 11a not supported by the AP 7250.

11a and 11g Turbo mode

Even higher throughput capability, up to 108 Mbps, is enabled.

User support

Each access point supports up to 253 simultaneous users, allowing plenty of room for growth.

WDS bridging

When used with 3Com wireless accessories, network access to remote on-campus buildings is economically
enabled.

Virtual AP

Two different client groups can be served as if there were two physical APs; all settings from SSID, 
encryption, and authentication can be customized on each Virtual AP.

SECURE

40/64 and 128/154-bit WEP, WPA, TKIP, TIP 

Basic and advanced encryption protect the privacy of data transmitted over the wireless LAN.

and AES encryption

Secure remote management

SSH and https enable remote management of the access point with strong encryption.

802.1x supplicant

Port-based authentication to an 802.1x-enabled switch port is supported for device authentication and rogue 
AP prevention.

Dynamic session key management and TKIP 

Dynamic key assignment improves security and simplifies deployment.

802.1x RADIUS server authentication

Network access only by authorized users is fostered and centralized across the network.

Access control lists

Access to network resources is controlled.

Client-to-client and uplink filtering

Direct communications is blocked between other wireless users associated to the access points.

MAC address filtering

Allows only specific WLAN cards to connect to the access point.

Dynamic VLAN assignment

Used with RADIUS authentication, users are assigned to an appropriate VLAN, further protecting access to
network resources.

COMPATIBLE AND FLEXIBLE

Modular, dual-mode radio architecture

Interchangeable radio slots support more wireless clients within the same coverage area with optional Mini 

(8250 and 8750)

PCI upgrade kits.

Simultaneous standard support

802.11a and 802.11g in same access point provide concurrent wireless connectivity for all 

(8250 and 8750)

802.11 a/b/g clients.

802.11g-802.11b backward-compatibility

11g radio supports both11g and 11b wireless users, preserving existing wireless investments. 

Wi-Fi certification

Interoperability with Wi-Fi certified products from other vendors is ensured.

Power over Ethernet (PoE) 

Hard-to-wire location problems can be solved; Ethernet cable supplies connectivity and electrical power;
802.3af-compliant power injector included with the Access Point 8250 and 8750; the AP 7250 ships with an
AC power adapter.

Virtual AP

A single AP can serve as two separate access points with completely configurable radio and security settings,
enabling open Internet access to guests while simultaneously providing secure, authenticated access to the
local network. 

Managed AP-capable (Fit or Fat)

Operation can occur as an individual, full-featured enterprise-class AP or as a secure "Fit" Managed Access
Point (MAP) when deployed with the 3Com Wireless LAN Controller WX4400 or Wireless LAN Switch
WX1200 mobility systems.

EASY TO USE MANAGEMENT

Simple installation

Network can be set up without drilling holes or running Ethernet cabling.

Integrated RSSI monitor

The RF spectrum in the vicinity of the physical AP can be remotely managed from any location that has a
network connection to the AP; occupied channels can be determined and appropriate adjustments made to
detect new friendly or rogue APs in the vicinity.

Wireless Infrastructure Device Manager 

Identifying and configuring network devices, running diagnostics, and monitoring performance can be done 

and wireless LAN device discovery tools

automatically.

Web-based administration

Network devices can be configured and managed from any location with any browser that supports HTML
and Java Script.

Save and load feature

Settings can be copied to wireless devices on the network, simplifying and speeding LAN setup.

3NS support 

Powerful yet simple-to-use network management is designed for small businesses.

SNMP support

Popular third-party network management programs can be used for remote, centralized management.

RADIUS accounting support

Billing by usage for hotspot and other commercial deployments is enabled.

RELIABLE

Dynamic rate shifting and auto network connect

Responds to physical conditions and RF interference by automatically moving between connection speeds.

Clear Channel Select

Problem-free connections are facilitated by selection of channels with the least traffic.

*Range depends on physical conditions, building construction, electrical devices in the area, and other environmental factors.
