This 2.4 GHz WiFi SoC for smart home appliances, intelligent locks, low-power cameras, and switch buttons is highly integrated with IEEE 802.11b/g/n baseband and RF circuit (power amplifier, low noise amplifier, RF balun, antenna switch, power management module). Thanks to multiple bandwidths, orthogonal frequency division multiplexing technology, and direct sequence spread spectrum and complementary code keying compatibility, Hi3861LV100 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.

RF and anti-interference

Mesh networking and comprehensive security

Multiple ecosystems and one-touch network access
