Power management and extended battery life are primary focus areas for embedded low-power Wi-Fi devices such as the SimpleLink WiFi Internet-on-a-chip solution. Handling power regimes effectively is fundamental for any battery-operated device. This problem is especially challenging for standards-based wireless devices that need to comply with certain requirements for Transmit power, Beacon interval, and data rates, as is the case with embedded Wi-Fi devices. This application note covers CC3100/CC3200 WiFi Internet-on-a-chip Networking sub-system power management (PM) capabilities, describes the basics of system behavior, and provides the basic toolbox for developers to design an optimal system.
