The mentioned blobs include a complete proprietary RTOS used to manage different tasks and events.

The mentioned blobs range in complexity depending on the peripheral they control. WiFi baseband seems to be comprised from a couple of FreeRTOS tasks while Bluetooth baseband appears to include an scheduler, events, many tasks and message echange mechanisms.

| WiFi | Expensive certification for IEEE 802.11 compliance; No direct meaning | The WiFi Alliance specifies the different WiFi revisions like WiFi4-7, which are a subset of the IEEE 802.11 in the sense, that they specify which features are required and which are optional for certification. WLAN and WiFi can in practice be used interchangeably. |
