Product Overview

The Cisco

WPC4400N Wireless-N Business Notebook Adapter (Figure 1) is the simple way to

add or upgrade wireless connectivity in your notebook computer. Just slide it into your notebook’s

PC card slot and enjoy high-speed wireless network access while retaining true mobility.

The Cisco WPC4400N uses the very latest wireless networking technology, Wireless-N (draft

802.11n). By overlaying the signals of multiple radios, Wireless-N’s multiple-input, multiple-output

(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 significantly 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 and Wireless-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.
