2 ENTERPRISE-CLASS 3COM ® WIRELESS LAN ACCESS POINTS <strong>7250</strong>/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 <strong>7250</strong>. ) 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 40/64- and 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 Compatible and Flexible Used with RADIUS authentication, assigns users to an appropriate VLAN, further protecting access to network resources. 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. 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. 3af-compliant power injector included with the Access Point 8250, 8500, and 8750; the <strong>AP</strong> <strong>7250</strong> ships with an AC power adapter. Easy to Use Management Simple installation No need to drill holes or run Ethernet cabling to set up your network. Dynamic Host Configuration Protocol Automatically assigns IP addresses to computers, simplifying configuration and management. (DHCP) support <strong>Wireless</strong> Infrastructure Device Manager Automatically identify and configure network devices, run diagnostics, and monitor and <strong>Wireless</strong> LAN Device Discovery tools performance. Web-based administration Works with any web browser that supports HTML and Java Script; lets you configure and manage network devices from anywhere. Save and load feature Copies settings to wireless devices on the network, simplifying and speeding LAN setup. 3NS support Powerful yet simple-to-use network management designed for small businesses. SNMP support Enables remote, central management using popular third-party network management programs. RADIUS accounting support Enables billing by usage for hotspot and other commercial deployments. Site survey tool Reliable Works with <strong>3Com</strong> enterprise wireless PC Cards to help you optimize the location and number of access points for your site. Dynamic rate shifting and auto Automatically moves between connection speeds in response to physical conditions and RF network connect interference. Clear Channel Select Selects the channel with the least traffic for problem-free connections. *Range depends on physical conditions, building construction, electrical devices in the area, and other environmental factors.
