the Baseband Device is the chipset that all iPhones and cellular models of the Apple Watch, iPad, iPad Air, iPad mini, and iPad Pro use that manages all the functions which require a cellular antenna. It has its own RAM and Firmware in NOR flash, separate from the ARM core resources. The baseband is a resource to the OS. The Wi-Fi and Bluetooth are managed by the main CPU, although the baseband stores it's MAC addresses in its NVRAM.
