FSC-BW126 IEEE 802.11ax/ac/a/b/g/n Compatible 2T2R WLAN and Integrated Bluetooth 5.2 Controller With PCI Express/HS-UART Mixed Interface Module Datasheet
■FSC-BW126 is a highly integrated single-chip 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. The FSC-BW126 provides a complete solution for a high-performance integrated wireless and Bluetooth device.
■FSC-BW126 baseband implements Multi-user Multiple Input, Multiple Output (MU-MIMO) Orthogonal Frequency Division Multiplexing (OFDM) with two transmit and two receive paths (2T2R). Moreover, FSC-BW126 provides one spatial stream space-time block code (STBC), Transmit Beamforming (TxBF) and Low Density Parity Check (LDPC) to extend the range of transmission.
■For legacy compatibility, Direct Sequence Spread Spectrum (DSSS), Complementary Code Keying (CCK) and OFDM baseband processing are included to support all IEEE 802.11b, 802.11g and 802.11a data rates. The high speed FFT/IFFT paths, combined with BPSK, QPSK, 16QAM, 64QAM, 256QAM, and up to 1024QAM modulation of the individual subcarriers, and rate compatible coding rate of 1/2, 2/3, 3/4, and 5/6, provide up to 1201Mbps for IEEE 802.11ax MIMO OFDM.
■For advanced 11ax spec, FSC-BW126 can receive with OFDMA (OFDM Access) technology. The high-order modulation scheme, such as 1024-QAM, can also be handled very well. Meanwhile, diff number of total subcarrier in the HE-LTF, such as 1x, 2x and 4x is considered. More networking efficiency can be achieved by 1x, and better channel estimation performance provided by 4x.
■FSC-BW126 MAC supports 802.11e for multimedia applications, 802.11i and WAPI (Wireless Authentication Privacy Infrastructure) for security, and 802.11n/ac/ax for enhanced MAC protocol efficiency. Using packet aggregation techniques such as A-MPDU with BA and A-MSDU, protocol efficiency is significantly improved. Power saving mechanisms such as Legacy Power Save, U-APSD, and MIMO power saving reduce the power wasted during idle time, and compensate for the extra power required to transmit MIMO OFDM. The FSC-BW126 provides simple legacy, 20/40/80MHz co-existence mechanisms to ensure backward and network compatibility.
