Secure High-Speed Wireless Connectivity With this secure, ultra high-speed wireless PC Card, mobile users can roam the office while accessing network resources, the Internet, and e-mail at speeds up to 108 Mbps. Super G packet bursting, compression, fast frames, and dynamic turbo features automatically boost performance dynamically, without user intervention. Dynamic rate shifting matches the best connection speed in response to physical and traffic conditions so wireless connections stay reliable. The PC Card supports advanced WPA and AES encryption as well as basic WEP encryption to protect wireless transmissions; the latest 802.1X authentication also helps protect against unauthorized users. 3Com's patented XJACK antenna extends for excellent reception then tucks safely away for traveling. For communication flexibility, users have a choice of connecting to the WLAN via ad hoc or infrastructure modes. Preset defaults make setup and operation easy. * It's wireless—no need to drill holes or run Ethernet cabling to set up your network * High-speed 108 Mbps data rate is ideal for multimedia or other high bandwidth applications * Support for Wi-Fi Protected Access 2 (WPA2) and 128-bit Advanced Encryption Standard (AES) encryption, and 40/64-bit, and 128- and 152-bit Wireless Equivalent Privacy (WEP) shared key encryption (for legacy clients) help keep wireless transmissions private * IEEE 802.1X server authentication helps ensure that only authorized uses access the network * Dynamic packet bursting increases throughput by sending more frames per given time period * Hardware compression automatically enhances throughput by compressing data frames in real time without affecting the host processor * Fast frames automatically extends frame size to transmit more data per frame, boosting efficiency with less overhead * Dynamic/static Turbo mode doubles the effective transmission rate by combining two channels; dynamic mode automatically adjusts bandwidth for need and environment * Dynamic rate shifting automatically matches the best connection speed in response to changing traffic and environmental conditions * Wi-Fi Multimedia (WMM) adds managed QoS, based on the IEEE 802.11e standard; critical for the new generation of delay-sensitive data, voice, and video applications * IEEE 802.11g is backward compatible with 11b networks; supports distances up to 100 meters (328 ft) * For communication flexibility, supports infrastructure mode through an access point, or ad hoc mode for direct peer-to-peer connectivity * Simple installation with plug-and-play operation and an easy-to-use configuration * Wireless Card Manager lets administrators creates profiles for mobile users that reflect specific settings for each place they roam, displays connection status, and features simple-to-use diagnostic tools * 3Com-patented XJACK antenna design extends for use and retracts for safe transport and to conserve power; no need to remove the PC Card from the notebook while traveling * Wi-Fi certification helps ensure interoperability with certified products from other vendors Product Specifications * Slot Type: Type II extended 32-bit PC Card slot (3.0-3.6V) * Drivers/Supported OS: NDIS 5: Windows, 2000, NDIS 5.1: Windows XP * Data Rates: 11g: 54, 48, 36, 24, 18, 12, 9, and 6 Mbps; 11b: 11, 5.5, 2, and 1 Mbps * Frequency Band: 2.4-2.4835 GHz * Modulation Technique: 802.11g: DSSS/CCK, OFDM; 802.11b: DSSS/CCK * Media Access Protocol: CSMA/CA * Operating Channels: 1-11 North America; 1-14 Japan, 1-13 Europe ETSI * Operating Range: 100 meters (328 feet) * Receive Sensitivity: 802.11g 54 Mbps: -69 dBm 48 Mbps: -70 dBm 36 Mbps: -74 dBm 24 Mbps: -80 dBm 18 Mbps: -82 dBm 12 Mbps: -84 dBm 9 Mbps: -86 dBm 6 Mbps: -87 dBm 802.11b: 11 Mbps: -86 dBm 5.5 Mbps: -88 dBm 2 Mbps: -91 dBm 1 Mbps: -93 dBm * Performance Features: Super G packet bursting, compression, fast frames, dynamic/static turbo mode, dynamic rate shifting * Security: WPA, WPA2, 802.11i, 128/192/256-bit AES, and 64/128-bit/256-bit WEP encryption; 802.1X with EAP-TTLS and PEAP authentication * Standards Conformance: Wi-Fi, IEEE 802.11g and 802.11b; AES, WEP, WPA and WPA2 certified; IEEE 802.1X, 802.1i, 802.11e; Microsoft Windows XP WHQL * Transmit Power Output: 802.11g: 17dBM (6, 9, 12, 18, 24, 36 Mbps), 14dBm (48, 54Mbps) 802.11b: 17dBM * Regulatory/Agency Approvals: EMC : FCC Part 15 Subpart C: 15.247, 15.207, CE, EN301 489-1/-17 (EN55022 and EN55024), EN 300 328 -1/-2, C-Tick Canada ICES-003, RSS210 Safety : EN60950-1: 2001, UL60950, R&TTE Art6.4, Taiwan DGT * Environmental Ranges: Operating temperature: 0° to 70° C (32° to 158° F) Non-operating temperature: -40° to 70° C (-40° to 158° F) Operating humidity: 10 to 90% non-condensing Non-operating humidity: 5 to 95% non-condensing * Installation, Configuration, and Management: Wireless Card Manager, pre-set defaults * LED Indicators: Link, Activity * Dimensions & Weight: With extended antenna Height: 0.5 cm (0.2 in) Length: 11.3 cm (4.4 in) Width: 5.4 cm (2.1 in) With retracted antenna Height: 0.5 cm (0.2 in) Length: 8.6 cm (3.4 in) Width: 5.4 cm (2.1 in) System Requirements * Notebook PC with Type II extended 32-bit PC Card slot (3.0-3.6V) * Notebook PC must be running Windows XP/2000 Package Contents * 3Com OfficeConnect Wireless 108Mbps 11g XJACK PC Card * CD-ROM with drivers and documentation * Quick Install guide * Warranty sheet Please Note * Not approved for sale in all countries.
