Power IoT and OTT devices like IP cameras with this STA WiFi SoC 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, Hi3881V100 is fully compliant with IEEE 802.11. Its powerful microprocessor, security, and interface versatility complement its faster system running on HUAWEI LiteOS/Linux with third-party components for open development.

RF and anti-interference

Compatible with Android, Linux, and LiteOS
