The AC1200 wireless router features dual wireless bands 2.4 GHz and 5 GHz, great for media-intense applications such as video streaming and online gaming. Beamforming focuses the WiFi signal directly to your smartphones, tablets, and laptops instead of sending out a general transmission. Plus, two detachable external antennas help strengthen the signal. The result is a more efficient network with a wider range. When your device doesn't have to work as hard to receive data, it means not only greater efficiency for you, but also a longer battery life for your connected devices.
