ENTERPRISE-CLASS 3COM® WIRELESS LAN ACCESS POINTS 7250/8250/8500/8750

The simple, secure way to network without wires

Feature	Benefit
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 Access Point 7250.)
11a Turbo mode	Provides even higher throughput capability, up to 108 Mbps.
User support	Each access point supports up to 253 simultaneous users, allowing plenty of room for growth.
Secure
40/64and 128-/154-bit WEP and	Basic and advanced encryption protect the privacy of data transmitted over the wireless LAN.
WPA 256-bit AES encryption
Dynamic security link (DSL)	Automatically assigns user-specific 128-bit encryption keys for wireless sessions.
Dynamic session key management and TKIP	Dynamic key assignment improves security and simplifies deployment.
802.1x RADIUS server authentication	Helps ensure that only authorized users can access your network and centralizes authorization
	of wireless users across your network.
Access control lists	Control access to network resources.
Client-to-client and uplink filtering	Block direct communications 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, assigns users 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
(8250/8500/8750)	optional Mini PCI upgrade kits.
Simultaneous standard support	802.11a and 802.11g in same access point provide concurrent wireless connectivity for all
(8250/8500/8750)	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	Ensures interoperability with Wi-Fi certified products from other vendors.
Power over Ethernet (PoE)	Solves hard-to-wire location problems; Ethernet cable supplies connectivity and electrical
	power. 802.3af-compliant power injector included with the Access Point 8250, 8500, and
	8750; the AP 7250 ships with an AC power adapter.
