Wireless-AC2.4GHz Wireless 802.11b/g/n is the most commonly used wireless standard. Because of this popularity, interference and lag are common in the 2.4GHz network, especially in areas with a lot of wireless networks. 5GHz Wireless-AC was designed to get past this interference. Using a different frequency allows 5GHz Wireless-AC to maintain high speeds and throughput. The trade off of 5GHz Wireless-AC is the range is reduced when compared to 2.4GHz wireless networks.Wireless-AC is built on a Dual-Band standard. Dual-Band Technology provides maximum flexibility allowing selection of the popular 2.4GHz frequency for long range applications or or selection of the faster, less-crowded 5GHz frequency for data intensive applications.With HW17ACU Wireless-AC, you have the option to connect to 5GHz network for high speed streaming or 2.4GHz for more distanced connection.
