Long Range 5.8GHz AR1021X Wireless HDMI Transmitter USB WiFi Module

USB WiFi Module Introduction

F1021UM13-W3 is a single chip 2x2 802.11a/b/g/n MIMO solution optimized for low-power embedded applications with dual-stream capability for both transmit and receive. Frame aggregation,reduced inter-frame spacing(RIFS),and half guard intervals provide improved throughput on the link. The AR1021X provides a robust communication solution,supporting maximal ratio combining (MRC),space-time block codes(STBC),and low density parity check(LDPC)codes.Additional performance optimization,such as 802.11n frame aggregation(AMPDU and A-MSDU)is supported,as well as low-over head host assisted buffering for reception of both A-MSDU and A-MPDU aggregates.The SDIO driver also provides SDIO bus transaction bundling for reduced over head.

These techniques can improve the performance and efficiency of applications involving large bulk data transfers(for example,file transfers or high-resolution video streaming).The typizacal data path consists of the host interface,mailbox DMA,AHB,memory controller,MAC,BB,and radio.The CPU drives the control path via register and memory access.External interfaces include USB,SDIO or SPI slave,reference clock, and front-end components,as well as optional connections such as UART,SPI/I2C,GPIO,JTAG.
