1、A dual‑band wireless network card that uses the latest 11A and 11N wireless technologies. It can search for network signals in the 2.4G and 5G frequency bands at the same time. It uses 5GHz channels to transmit data, and has excellent performance with low interference. 2、Response to the rapid increase in the amount of network data, the new generation of 802.11a wireless transmission technology, compared with the existing 11n technology, greatly increases the transmission rate of 5GHz by nearly three times, allowing you to wirelessly enjoy wired network‑like high‑speed Internet surfing. Whether it is Online Game or high‑quality audio and video, the quality of data transmission is more perfect, so to activate the 5GHz frequency band for super‑speed Internet surfing, 11a is of course the best choice. 3、Also supports the analog AP hotspot function, which converts the wired network into a wireless signal output; through simple AP mode settings, the network card is used as an AP router, which is convenient for users to share the Internet through wireless network cards. 4、Comply with IEEE 802.11a, IEEE 802.11n, IEEE 802.11g, and IEEE 802.11b standards, and provide two working modes: centralized control (Infrastructure) and peer‑to‑peer (Ad‑Hoc). 5、2T2R dual antenna technology, built‑in 2.4G/5G antenna; dual channel transmission, faster and more stable transmission efficiency. Both the 2.4G frequency band and the 5G frequency band have a wireless upload and download rate of 300Mbps, which greatly meets the needs of users for large‑volume data transmission. 6、MIMO technology is used to create multiple parallel spatial channels to solve the problem of broadband sharing. The wireless transmission rate is up to 300Mbps. CCA technology is used to automatically avoid channel interference and make full use of channel bundling advantages to ensure that the use of wireless networks will not affect neighbors. 7、It supports 64/128‑bit WEP, WPA/WPA2/802.1X and other wireless encryption methods to protect your wireless network from infringement and embezzlement in all aspects. 8、Compatible with mainstream IPTV set‑top boxes, Internet TVs, network players and other devices, you can move home Internet devices at will, and enjoy more fun in Internet life. 9、Compatible with mainstream operating systems such as for Windows XP, for Windows Vista, for Windows 7, for MACOS, for LINUX, etc., so you can use it with confidence.
