FSC-BW126 Dual Band 2.4G & 5G Wi-Fi 6 and Dual Mode Bluetooth 5.2 Module

FSC-BW126 is a dualbandwifi bluetooth combo module,that support 2-stream 802.11ax solutions with Multi-user MIMO (Multiple-Input, Multiple-Output) with Wireless LAN (WLAN) PCI Express network interface controller and HS-UART mixed interface. It combines a WLAN MAC, a 2T2R capable WLAN baseband, and RF in a single chip. WiFi 6, which refers to the 6th generation of wireless networking technology. Compared with the 5th generation, the first feature is the speed increase, the network connection speed increased 1.4 times. The second is technological innovation. The application of OFDM orthogonal Frequency division multiplexing technology and MU-MIMO technology enables Wi-Fi 6 to provide stable network connection experience for devices even in multi-device connection scenarios and maintain smooth network operation. The FSC-BW126 provides a complete solution for a high-performance integrated wireless and Bluetooth device.
