Product Specs

Overview
H181 is a highly integrated 2.4 GHz Wi-Fi SoC that packs the IEEE 802.11b/g/n baseband and RF
circuit. The RF circuit consists of the power amplifier (PA), low noise amplifier (LNA), RF balun, antenna
switch, and power management module. It supports 20MHz standard bandwidth, and provides a physical
layer rate up to 72.2Mbit/s.
The Hi3881V100 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.
Hi3881V100 integrates a high-performance 32-bit microprocessor, a hardware security engine.
Hi3881V100 SoC is applicable to IPC,IoT low-power intelligent products such as smart home
appliances, intelligent lock, set box etc .
