MUMBAI, India, Feb. 6 -- Intellectual Property India has published a patent application (202641007270 A) filed by Vellore Institute Of Technology, Chennai, Tamil Nadu, on Jan. 24, for 'energy-efficient wake-up receiver system for an internet of things (iot) end node.'
Inventor(s) include P. N. Renjith; G. Sudhakaran; and Suhani Panda.
The application for the patent was published on Feb. 6, under issue no. 06/2026.
According to the abstract released by the Intellectual Property India: "The present disclosure relates to an energy-efficient wake-up receiver system (100) for an Internet of Things (IoT) end node. The system includes ultra-low-power wake-up receiver module (102) that continuously monitors wireless communication channel while consuming substantially less power than a primary radio transceiver (104-2), allowing a main processing and communication subsystem (104) to remain in a low-power sleep state. The wake-up receiver module (102) includes antenna (102-1), matching network (102-2), signal detection path including envelope detector (102-3), filter (102-4), and amplifier chain (102-5), signal decoder and pattern detector (102-6) for extracting device-specific address, address matching circuit (102-7), and authentication module (102-8) for validating embedded authentication token. A wake-up control interface, implemented by wake-up interrupt generator (102-11), issues wake-up interrupt only upon successful address and authentication validation, thereby activating microcontroller unit (104-1) and primary radio transceiver (104-2). This architecture decouples continuous listening from high-power communication, reducing idle energy consumption."
