  • the zero-power device When the zero-power device approaches the network device, the zero-power device is within the near field formed by the radiation of the network device antenna.
  • the network device is a reader/writer of the Radio Frequency Identification (RFID) system. Therefore, the antenna of the zero-power device generates an induced current through electromagnetic induction, and the induced current drives the low-power chip circuit of the zero-power device. It realizes the demodulation of the forward link signal and the modulation of the backward link signal.
  • the zero-power device can use backscatter or extremely low-power active transmission to transmit the signal.
  • Passive zero-power devices do not need built-in batteries to drive either the forward link or the reverse link, and are truly zero-power devices. Passive zero-power devices do not require batteries, and the RF circuit and baseband circuit are very simple. For example, they do not require devices such as LNA, PA, crystal oscillator, analog to digital converter (ADC), etc. They have many advantages such as small size, light weight, very low price, and long service life.
  • Semi-passive zero-power devices do not require built-in batteries to drive either the forward link or the reverse link.
  • the energy stored in the capacitor used in the work comes from the radio energy collected by the RF energy harvesting module. It is a truly zero-power device.

  • Zero-power devices used in some scenarios can also be active zero-power devices, which can have built-in batteries. Batteries are used to drive The low-power chip circuit of the active zero-power device. It realizes the demodulation of the forward link signal and the modulation of the backward link signal. However, for the backscatter link, the zero-power device can use backscatter or extremely low-power active transmission to transmit the signal. Therefore, the zero power consumption of the active zero-power device is mainly reflected in the fact that the signal transmission of the reverse link does not need to consume the power of the zero-power device itself, but uses the backscattering method.
  • the built-in battery powers the RFID chip, increases the reading and writing distance of the tag, and improves the reliability of communication. Therefore, it can be used in some scenarios with relatively high requirements for communication distance, reading delay, etc.
  • This type of zero-power device uses the above-mentioned backscattering method for uplink data transmission.
  • This type of zero-power device does not have an active transmitter for active transmission, but only has a backscattering transmitter. Therefore, when this type of zero-power device sends uplink data, the network device needs to provide a carrier, and this type of zero-power device performs backscattering based on the carrier to achieve uplink data transmission.
  • This type of zero-power device uses an active transmitter with active transmission capability for uplink data transmission. Therefore, when sending uplink data, this type of zero-power device can use its own active transmitter to send uplink data without the need for network equipment to provide a carrier.
  • Active transmitters suitable for zero-power devices can be, for example, ultra-low power ASK transmitters, ultra-low power FSK transmitters, etc. Based on current implementations, when transmitting a 100 microwatt signal, the overall power consumption of this type of transmitter can be reduced to 400 to 600 microwatts.

Zero-power devices can determine whether to use backscatter or active transmitters for active transmission based on different situations (such as different power levels, different available environmental energy levels), or based on the scheduling of network devices.
