Hisilicon Hi3881 2.4G Wireless IPC Embedded SDIO WiFi Module
2.4G Wireless IPC Embedded SDIO WiFi Module Hisilicon Hi3881 With External Antenna
3181A-S is a highly integrated 2.4 GHz Wi-Fi module that support the IEEE 802.11b/g/n baseband and RF circuit. It supports 20 MHz standard bandwidth and 5 MHz/10 MHz narrow bandwidth, and provides a physical layer rate up to 72.2 Mbit/s. Wi-Fi baseband supports the orthogonal frequency division multiplexing (OFDM) technology and is backward compatible with the direct sequence spread spectrum (DSSS) and complementary code keying (CCK) technologies, offering various data rates defined in the IEEE 802.11 b/g/n protocol.
