> All ARM SoCs come with radio processors that are running a non-trivial piece of software with full access to the system memory, which is responsible for power management, boot sequence and wireless communications. It is by definition network connected. The high-end ones used for flagship smartphones/tablets do, but low-end ones used in cheaper tablets/TV boxes and more specialized hardware often don't have any radio interface.
