Long-range transmission, up to 1km or and further within the visual distance Channel bandwidth options of 1/2/4/8 MHz Support Sub-1 GHz frequency bands: 902~928 MHz Max output power:21dBm High data rate, single-stream max. data rate of 32.5 Mbps @ 8 MHz or 15 Mbps @ 4 MHz channel HC01P is a Wi-Fi HaLow module with mini PCIe interface, which operates in 902 - 928MHz, with maximum data rates of 32.5Mbps and up to 1-2km transmission range. It meets IEEE 802.11ah standard, which is specifically designed for battery-operated devices, allowing them to remain in longer sleep and idle states without frequent wake-ups. This significantly reduces power consumption and extends the device's battery life.
