General Description
The WAH0070-US is the IEEE 802.11ah a Wi-Fi HaLow module. It is operating in the Sub 1GHz license-exempt band, offering longer range and lower power connectivity necessary for internet of things (IoT) applications. It enables streamlined data transfer interoperability with existing Wi-Fi networks while meeting up to 1Km long-range data transfer with low power onsumption requirements. It integrated Newracom NRC7394 and an external RF front-end module (FEM) which can increase transmission power up to 20 dBm.It outputs the accurate power for each channel through the temperature sensor integrated in the SoC and calibration at the factory. On-board serial flash can be used for user application programs and OTA software update and store MAC address, calibration data and information. It also can support execution in place (XIP) feature with a 16KB internal cache memory
