Wireless 11a/b/g PC Card with XJACK® Antenna
Universal, Secure, High-Speed Wireless Networking
The 3Com® Wireless 11a/b/g PC Card with XJACK®Antenna supports all three existing IEEE 802.11 networking standards—11a, 11b, and 11g. That means you can stay connected, no matter what wireless environment you're in: the office, at public wireless "hot spots", at home, or on the road.
With this versatile PC Card, laptop users can access network resources, the Internet, and e-mail at 11-Mbps speeds on 11b wireless networks, or on 11a or 11g wireless networks, at speeds up to 54 Mbps—ideal for multimedia applications using audio and video. And, Wi-Fi certification helps ensure interoperability with Wi-FI-certified 11a, 11b, and 11g products from other vendors.
The 3Com Wireless 11a/b/g PC Card delivers one of the most robust suites of standards-based, next-generation security features on the market today. Wi-Fi Protected Access 2 (WPA2), IEEE 802.1x authentication, and EAP authentication protocols all protect against unwanted network access. MD5 algorithm, AES (Advanced Encryption Standard) and WEP (Wireless Equivalent Privacy) shared-key encryption combine to protect the privacy of all wireless data.
This card offers time-saving features which make it an intelligent choice for busy mobile users. With 3Com Wireless Utility software, you can create profiles with specific wireless LAN settings for each place you travel—just click the proper profile, and you are configured for connection. And 3Com's patented XJACK antenna extends for excellent reception then tucks safely away for traveling.
Multiple standards support brings universal, complete access to IEEE 802.11a, 11b, and 11g wireless networks.
Wi-Fi a/b/g Certified helps ensure the PC card will interoperate with Wi-Fi compatible products from other vendors.
IEEE 802.1x Network Access Control and EAP-TLS, PEAP, and EAP-TTLS protocols deliver the latest, most effective authentication and simplify management.
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.
Supports speeds up to 54 Mbps on 802.11g or 802.11a networks—nearly five times the speed of existing 802.11b networks.
In turbo mode, supported 11a and 11g network speeds jump to 104 Mbps when used with 3Com Wireless LAN Access Point 8500 or Access Point 8700.
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.
3Com-patented XJACK antenna design extends for excellent wireless LAN performance and retracts for safe transport—no need to remove the PC Card from the notebook.
3Com Wireless Utility software creates profiles that reflect specific configurations for each place wireless notebook users travel—just click the proper profile to match the location; it also displays connection status and features simple-to-use diagnostic tools.
