High-speed wireless transmission, dual frequency (2.4GHZ/150Mbps, 5.8GHZ/433Mbps） The wireless wifi dongle 1200Mbps uses new Generation 802.11AC Wireless Transmission Technology, The transmission rate has increased by 3 times at 5GHz, let you have more Internet speed to do the lag-free HD video streaming and gaming ,enjoy the Wired Internet speed.also supports the IEEE802.11a/n/b/g/ac. The 1200Mbps wifi adapter uses the USB 3.0 interface standard,Provide faster and more efficient data transfer rates, Backward compatible with USB2.0 and USB1.1 interface and Used for more equipment. USB wifi adapter Supports AP Routing function and Set up a wireless LAN, To achieve more than people to share Internet access, the wifi dongle also Supports WPS,64/128bit,WEP, WPA/WPA2 and WPA-PSK/WPA2-PSK Advanced Security Mechanisms and Encryption,Let the Internet more secure. Antenna 360 degrees flexible rotation and 90 degrees flip, let the Wireless network adapter more easy to receive the wifi signal, the 5DBI Antenna with the Gain function, to increase the signal receiving capacity from farther away. The chip uses the RTL8812BU, let the wireless USB wifi dongle works more smoothly.
