Years ago, city engineers figured out two lanes of traffic were better than one. Then they figured our four lanes were better than two. The same revolution is happening in the Wi-Fi industry with new quad antenna 802.11ac Wi-Fi equipment boasting router connection speeds of up to 1900 Mbps.
At the head of the pack is Alfa’s newly released AWUS1900, a four-antenna USB Wi-Fi receiver compatible with Microsoft Windows 7, 8/8.1, and Windows 10. This connects to your computers USB port with enclosed USB 3.0 cable and boosts the Wi-Fi performance of that specific PC. This is not a router or repeater.
We completed a test here where we transferred a file of 1.69 Gbps from our router’s storage device (Tenda AC1900 router). We then attempted to transfer this file to the same computer on the network, two different ways. First via the laptop’s built-in Wi-Fi card, a standard 802.11n card capable of 300 mbps max transfer. The file took 350 seconds to transfer to the computer.
We then deleted the file and connected the same laptop to the Tenda router with this Alfa AWUS1900 802.11ac USB adapter, and achieved an actual connection rate to the router of 1.3 Gbps (that’s gigabits per second!). The transfer time from the network storage drive was just 70 seconds. That went 5 times faster with the Alfa AWUS1900.

How does its 802.11n range compare with the Alfa AWUS036NH and other wifi USB adapters with good range?
