Linksys WEC600N Ultra RangePlus Dual-Band Wireless-N ExpressCard Network Adapter

The Ultra RangePlus Dual-Band Wireless-N ExpressCard is the simple way to add or upgrade wireless connectivity in your notebook computer. Just slide it into your computer's ExpressCard slot and enjoy incredible high-speed wireless network access while retaining true mobility. The Dual-Band Wireless-N ExpressCard uses the very latest wireless networking technology, Wireless-N (draft 802.11n). By overlaying the signals of multiple radios for each band, Wireless-N's ""Multiple In, Multiple Out"" (MIMO) technology multiplies the effective data rate. Unlike ordinary wireless networking technologies that are confused by signal reflections, MIMO actually uses these reflections to increase the range and reduce ""dead spots"" in the wireless coverage area. The robust signal travels farther, maintaining wireless connections much farther than standard Wireless-G. With Wireless-N, the farther away you are, the more speed advantage you get. It works great with standard Wireless-G, -A, and -B equipment, but when both ends of the wireless link are Wireless-N, the throughput can be increased even more by using twice as much radio band, yielding speeds far faster than standard Wireless-G. Dual-band wireless networks operate in both the 2.4 and 5 gigahertz radio bands at the same time, effectively doubling the available wireless bandwidth. For instance, you could set up your network to handle video streaming on one radio band, and use the other band for simultaneous data transfers, avoiding any interference or collisions that would degrade the video performance. The Dual-Band Wireless-N ExpressCard allows you to connect using whichever band works the best for your situation. "
