Radio band selectable to avoid wireless congestion! The Ultra RangePlus Wireless-N PCI Adapter with Dual-Band adds wireless connectivity to your desktop computer. Install it into an available slot in your computer, and enjoy great high-speed wireless network access without running wires. The Wireless-N PCI Adapter uses the very latest wireless networking technology, Wireless-N (draft 802.11n). By overlaying the signals of multiple radios for each band, Wireless-Ns Multiple In, Multiple Out (MIMO) technology is designed to multiply 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 far beyond standard Wireless-G by using twice as much radio band. Dual-band wireless networks are designed to operate in both the 2.4 and 5 gigahertzradio 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 Wireless-N PCI Adapter with Dual-Band allows you to connect using whichever band works the best for your situation.
