Even large homes and workplaces can now benefit from excellent Wi-Fi performance thanks to Alfa's AWUS1900 Wi-Fi adapter. This remarkable device is not a router or repeater, but a simple adapter that plugs into your computer to maximise its speed and connectivity while eliminating dead spots and delays. Whether you're streaming HD video or performing a local file transfer, the four dual-band antennas provide long-range performance that's up to the task. The device connects via the included USB 3.0 cable and optimises your 802.11ac WLAN for a combined rate of up to 1900 Mbps. This means maximum download and transmission speeds - even when multiple users are accessing the network.
