The Belkin Wireless Pre-N Network Adapter Card Works with other Pre-N technologies like Pre-N routers and access points and is necessary if you want to take full advantage of all the improvements made upon wireless networking like greater coverage and data transfer rates. Belkin Utilizes true Multiple Input Multiple Output (MIMO) technology in all its Pre-N products, and to you that means faster data transfer rates (108Mbps) and wider coverage (800% wider coverage than standard 802.11g !). Airgo Networks MIMO uses a smart antenna technique that employs multiple antennas to transmit and receive multiple wireless signals on each antenna.
