2.4GHz frequency band: The signal strength decays slowly, the penetration is stronger, the transmission distance is long, and the problem of wall penetration is solved. 5.8GHz frequency band: bandwidth, fewer existing users, less interference, low latency, and purer and smoother signals.Equipped with two high-gain -band omnidirectional antennas to increase the signal coverage area and coverage depth, without fear of wall blockage, and low signal attenuation.Using USB3.0 high-speed transmission interface, the transmission is faster and more stable, and it is backward compatible with USB2.0 interface devices.Efficient heat dissipation and stable operation The double-sided heat dissipation design of the fuselage can bid farewell to the embarrassment of poor heat dissipation, instability, and hardware overheating and aging of the USB network card.The computer receives WiFi without pulling the network cable. The network cable is messy and destroys the decoration layout. It becomes a wireless receiver in seconds, and receives WiFi for the computer to surf the Internet wirelessly.Type: Band Wireless CardTransmission rate: 1300MbpsInterface type: USBWireless Standards: IEEE 802.11g, IEEE 802.11b, IEEE 802.11n, IEEE 802.11a/acWorking frequency band: 2.4GHz/5.8GHzSupport Protocol: IEEE 802.11ACNetwork speed support (WiFi Speed ): 2.4GHz--400Mpbs, 5.8GHz--867MpbsNetwork Mode (Frequency): Band 2.4GHz + 5.8GHzDriver-free applicable system (OS): Windows Vista/XP/7/8/10/11Material: ABScolour: blackPackage Contents:1 x Network CardOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
