This cost-effective chip powers your smart home with a IEEE 802.11b/g/n baseband and RF circuit (power amplifier, low noise amplifier, RF balun, antenna switch, and power management module). Thanks to multiple bandwidths, orthogonal frequency division multiplexing technology, and direct sequence spread spectrum and complementary code keying compatibility, Hi3861V100 is fully compliant with IEEE 802.11. Its powerful microprocessor, security, and interface versatility complement its running on HUAWEI LiteOS with third-party components for open and intuitive development and debugging.
