US Patent 10182400 Low-power wake-up mechanism for wireless devices

Systems and methods are described for a wireless electronic device including a primary wireless transceiver and a secondary wireless transceiver. An electronic processor is configured to operate the wireless device and communicate through the primary wireless transceiver when in an active mode and to monitor the secondary wireless receiver for a wake-up signal when in a sleep mode. The electronic processor transitions from the sleep mode into the active mode in response to detecting the wake-up signal through the secondary wireless receiver.
