The RangePlus Wireless Notebook Adapter uses the very latest wireless networking technology to achieve extended range. 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. And with MIMO, the farther away you are, the more speed advantage you get. It works great with standard Wireless-G and -B equipment, but when both ends of the wireless link use RangePlus technology, the throughput can be increased even more by using twice as much radio band.
