1、Using the latest wireless transmission technology, the wireless transmission rate can reach up to 300Mbps, and the data transmission in the local area network is more efficient, effectively reducing network delays, and making voice, video, online games, and online on-demand smoother. 2、Adopt 2×2 MIMO (Multiple Input Multiple Output) architecture, with two smart omnidirectional antennas inside and outside, and multiple signals are sent and received, which can greatly enhance its wireless reception capability and enhance the stability of wireless signals. 3、CCA (Clear Channel Assessment) empty channel detection technology is also used. When wireless signal interference is detected in the surroundings, the bandwidth mode can be automatically adjusted to avoid channel interference and make the wireless signal more stable. When the interference disappears, idle channels can be automatically bundled again, making full use of the advantages of channel bundling to improve wireless performance. 4、Wireless network card come with simulate Access Point function, easily set up wireless LAN. 5、In the absence of a wireless router/Access Point, plug the wireless network card into the computer and transfer to the access point mode. At this time, it is equivalent to a wireless Access Point, which can support Wi‑Fi shared internet access of multiple computers.
