Since launching earlier this year, the Alfa AWUS1900 has turned heads with its unique look, and its unique place in the market as a low cost USB AC1900 upgrade. If you own an 802.11ac router, especially one with three or four antennas, in addition to getting better range, the AWUS1900 will also give you improved bandwidth capabilities back to your network compared to an internal Wi-Fi card built inside a laptop or desktop.
