It is also USB 3.0 capable, and will perform up to 10 times faster than USB 2.0 when plugged into a USB 3.0 port. Easy setup will have users immediately experiencing a faster Wi-Fi connection with better range. Why Wireless-AC? Wireless-AC is engineered to move more data faster—up to three times faster than Wireless-N. The result is smooth video streaming, more responsive gaming experiences and all-around improved connectivity. Faster data rates are achieved by using higher modulation (256- QAM for AC vs. 64-QAM for N) that allows much more data to be transmitted within the same time period. Wireless-AC also provides twice the channel bandwidth of Wireless-N and means that your data can travel on multiple parallel paths. Your mobile devices also gain extended battery life by achieving optimal transfer speeds. Wireless-AC is backward-compatible with a/b/g/n wireless protocols. – Selectable Dual Band (2.4 or 5 GHz) – Operates on either band to help avoid interference. – USB 3.0 Capable – USB 3.0 transfer rates are 10x faster than USB 2.0. – Advanced Wireless Security – Safeguard your network with wireless WPA/WPA2 encryption and Wi-Fi Protected Setup. – Easy Setup – Features setup wizard and Wi-Fi Protected Setup for quick installation.
