Abstract
An electronic device has first and second circuitry. A wireless trigger signal at the first circuitry causes the second circuitry to power up to receive a second wireless signal. The second signal is according to a radio access technology for which the trigger signal is incompatible. In various embodiments the first circuitry (a low power receiver) may autonomously power up upon expiration of a timer. One or more security checks can be performed at various steps, each step conditional on passing the previous security check. The first circuitry operates at a lower power than the second circuitry which comprises a broadband radio. For example, the first circuitry might be a Bluetooth low energy receiver, and a trigger signal there causes a WLAN receiver to power up in order to download software/firmware updates or user content while the device is enroute between the manufacturer and end user.
