Publication number: 20250233607Abstract: Compact battery powered wireless devices such as automotive key fobs that enable secure vehicle access can realize improved battery life and user experience by including a wake-up receiver that wakes up near-field communication (NFC) circuitry and other circuitry such other communication circuitry (e.g., ultrawideband or Bluetooth circuitry) that is configured to operate with an antenna system that enables the device to detect a wake-up signal generated by an external NFC device at much longer distances than conventional wake-up receivers, even at low power levels, by modifying the wake-up receiver to operate in a frequency band in which the near-field regime can extend to at least one meter and wireless signals are not strongly attenuated by a user's body or clothing. The frequency band can also be chosen to coincide with communication frequencies used by legacy NFC and radiofrequency ID readers such as 13.56 MHz.Type: ApplicationFiled: January 13, 2025Publication date: July 17, 2025Inventors: David Veit, Frank Graeber, Hubert Tockner, Frank Leong

Publication number: 20240288556Abstract: A method is provided for estimating a time-of-flight (TOF) in a wireless communication between first and second devices. The method includes receiving a signal, transmitted from the second device, at first and second antennas of the first device. The second antenna is spaced apart from the first antenna on the first device. A difference in arrival time of the received signal at the first antenna and at the second antenna is computed by the first device. A non-line-of-sight (NLOS) signal path of the received signal in a TOF estimation is compensated for using the difference in arrival time of the received signal between the first antenna and the second antenna. In another embodiment, a communications device having multiple antennas is provided that compensates for the NLOS signal path using the method.Type: ApplicationFiled: February 16, 2023Publication date: August 29, 2024Inventors: Michael Schober, David Veit, Stefan Tertinek
