a system on a chip (SOC) with a built-in TCP/IP protocol stack that allows microcontrollers to connect to Wi-Fi networks and perform a variety of functions, including:

1. Networking
2. Data processing
3. P2P connectivity
4. Web server
5. Managing Wi-Fi network operations
6. Hosting applications
7. Offloading Wi-Fi networking functions from other application processors
