Incredible Performance from 2 Dual-Band Antennas Alfa's AWUS036AC is designed for those with a serious need for wireless Internet speed. Its 2x dual-band antenna (2.4GHz / 5GHz) setup lets you connect to AC networks at a tire-burning 867Mbps and to N networks up to a whopping 300Mbps. As the new wireless draft 802.11ac technology was developed to optimize the handling of heavy data transfer demands like video streaming and large files syncing, the AWUS036AC is the ultimate tool for taking advantage of the next wave in wireless connectivity. Yet, despite all its power and speed, this little Alfa comes in a really small form factor akin to a USB thumb drive. Removable Rubber Duck Antennas for Powerful Flexibility The AWUS036AC ships with 2 detachable 5dBi dual-band dipole antennas. While these are powerful in their own right, the RP-SMA female antenna port can accept antenna upgrades to boost your wireless range and signal even more. Once your antenna of choice is connected, this turns into a standalone Wi-Fi receiver that puts the connected world at your fingertips. Alfa is also seriously invested in your privacy, it includes support for enterprise class wireless security WEP 64-Bit, WEP 128-Bit, WPA-PSK and WPA2-PSK. No Introductions Are Needed Whether you're using a desktop, laptop or a netbook, the Alfa AWUS036AC requires no more than a USB port. Slide it in, install the Utility, and Connect to your network. The USB 3.0 interface keeps the connection to your computer strong and snappy at super transfer speeds of 5Gbps. Best of all, the Alfa measures just 85mm x 26mm x 12mm and weighs in at a super-light 25 grams so that it goes anywhere you do and brings wireless wonder along. It also by far outperforms the wireless cards that are built into newer laptops, and enhances both the range and signal quality at longer distances.
