¿µ¹®³»¿ë¿ä¾à | The standard is intended to wake up MCU of a sleeping IoT device by sending amplitude-modulated (OOK, On Off Keying) multiple wake up signals to a WUR module (Wake Up Radio Module). The wireless wake up module generates an interrupt signal to wake up MCU sleeping after receiving the wake up signal. The standard sets out the requirements for implementing the technology. And specifically, Chapter 5 presents the communication procedure, WUR module architecture, Chapter 6 PHY(Modulation and Demodulation), and Chapter 7 MAC(Protocol, Data Format). | ||
