FSC-BW121 Bluetooth 5.0 +WLAN 802.11 a/b/g/n/ac Module Datasheet
■FSC-BW121 is a Wi-Fi / Bluetooth combo module that support 1-stream 802.11ac solutions with Multi-user MIMO (Multiple-Input, Multiple-Output) STA mode with integrated Bluetooth Smart Ready controller, SDIO (SDIO 1.1/2.0/3.0) interface, and HS-UART mixed interface. It combines a WLAN MAC, a 1T1R capable WLAN baseband, and RF in s single chip. It provides a complete solution for a high-performance integrated wireless and Bluetooth device.
■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. Differential phase shift keying modulation schemes, DBPSK and DQPSK with data scrambling capability are available, and CCK provides support for legacy data rates, with long or short preamble. The high speed FFT/IFFT paths, combined with BPSK, QPSK, 16QAM, 64QAM and 256QAM modulation of the individual subcarriers, and rate compatible coding rate of 1/2, 2/3, 3/4, and 5/6, provide up to 433.3Mbps for IEEE 802.11ac MIMO OFDM.
■FSC-BW121 builds in an enhanced signal detector, an adaptive frequency domain equalizer, and a soft- decision Viterbi decoder to alleviate severe multi-path effects and mutual interference in the reception of multiple streams. Robust interference detection and suppression are provided to protect against Bluetooth, cordless phone, and microwave oven interference.
■FSC-BW121 supports fast receiver Automatic Gain Control (AGC) with synchronous and asynchronous control loops among antennas, antenna diversity functions, and adaptive transmit power control functions to obtain better performance in the analog portions of the transceiver.
■FSC-BW121 MAC supports 802.11e for multimedia applications, 802.11i and WAPI (Wireless Authentication Privacy Infrastructure) for security, and 802.11n/802.11ac 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. FSC-BW121 provides simple legacy, 20MHz/40MHz/80MHz co-existence mechanisms to ensure backward and network compatibility.
■FSC-BW121 Bluetooth controller complies with Bluetooth core specification v5.0, and supports dual mode (BR/EDR + Low Energy Controllers). It is compatible with previous versions, including v2.1 + EDR. For BR/EDR, it supports scatternet topology and allows active links in slave mode, and active links in master mode. For Low Energy, it supports multiple states and allows active links in master mode. The links in BR/EDR and LE can be active simultaneously.
