[DETAIL] 600m dual-band Bluetooth wireless card 2.4g/5g computer wireless USB Bluetooth wifi 2-in-1 wireless card Wireless WiFi+ Bluetooth 2-in-1 adapter, in line with IEEE802.11AC,IEEE802.11B, IEEE802.11G, IEEE802.11N wireless W transmission standards, WIFI transmission rate up to 2.4GHz 150Mbps/5.8GHz 433Mbps. Standard wireless ACC empty channel detection technology is adopted to avoid channel interference when there is wireless model interference around, so that the wireless signal is more stable. When the interference disappears, the idle channel can be automatically bundled to make full use of the advantages of bundling and improve the wireless performance. Not only that, because most computers on the market do not have Bluetooth function, this product can make the device without Bluetooth function with Bluetooth multi-function application; For example: Bluetooth speaker/headset, Bluetooth mouse/keyboard, wireless printing, wireless transmission of pictures and sharing; It can save you a USB interface on your computer, save the cost of buying more than one wireless WIFI card, and easily enjoy the happiness of wireless Internet access. Product Description: Dual-band 600M USB wireless card + Bluetooth 5.0 2-in-1 The wireless card supports 802.11AC wireless devices and is backward compatible with 802.11b /g/n, making it possible to transmit multiple HD streams simultaneously within the home range. Wireless card + Bluetooth 4.2 Adapter performance design makes it particularly convenient for both desktop and portable laptops. Encryption and Security: Advanced WPA and WPA2 encryption technology AES and TKIP on hardware to reduce power consumption and speed up encryption Provides worldwide channel range adjustment Maximizes multimedia performance when transmitting simultaneously in Bluetooth and WLAN modes, allowing a single radio frequency IC to co-exist with a single baseband IC in several wireless transmission modes, advanced local area network security features, including WAP, WAP2, 802.11i and 802.11x [Bluetooth] Adaptive Frequency Hopping Fully compatible with Bluetooth v5.0+EDR Forward compatibility Bluetooth v2.0 and v3.0 compatibility Supports seven Bluetooth device connections at the same time Compatible with Bluetooth Class 2 specifications, it has 18dbm power and 10-20 meters transmission distance Product characteristics Main chip: RTL8821CU Bluetooth description: Bluetooth version V5.0 Bus type usb Transmission distance 10-20 meters RF power 10dBm (Max.)
