In an implementation, an auxiliary path for waking up a radio frequency (RF) radio of a low-power device is disclosed. The auxiliary path includes peak detector circuitry, pattern detector circuitry and a battery switch. The peak detector circuitry is operable to detect the presence of a RF field at a RF antenna of the low-power device. The pattern detector circuitry is enabled by the presence of a RF field and is operable to detect a time pattern in an amplitude envelope of a wakeup signal received at the RF antenna of the low-power device. The battery switch is operable to connect battery power to a RF radio of the low-power device when the time pattern is detected. Once powered, the RF radio establishes communication with a wakeup device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Auxiliary path for low-power device wakeup","description":"The technology described herein relates to auxiliary wakeup for low-power devices.
