SYNC SCATTER LOW POWER BACKSCATTER WAKE UP RECEIVER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18553617 titled 'SYNC SCATTER LOW POWER BACKSCATTER WAKE UP RECEIVER
Simplified Explanation
The patent application describes a method for waking a transceiver in an integrated tag device to communicate directly with commodity Wi-Fi transceivers using backscatter modulation.
- The method involves sensing a Wi-Fi wake-up signal, then detecting and transmitting a payload packet using a backscatter transmission circuit.
- The transceiver includes a wake-up receiver with an energy-detection based architecture and a sync receiver that enables backscatter transmission in sync with the payload.
- The sync receiver is activated by receiving two pre-specified Wi-Fi compatible packets, allowing for efficient communication with Wi-Fi transceivers.

Questions about the Technology
How does the sync receiver enable synchronized backscatter transmission?
The sync receiver is activated by receiving two pre-specified Wi-Fi compatible packets, allowing it to detect a payload packet and create a backscatter enable signal synced with the payload.
What are the potential benefits of using backscatter modulation for communication with Wi-Fi transceivers?
Backscatter modulation enables low-power communication and efficient wake-up of transceivers, leading to extended battery life and improved efficiency in data transmission.
Original Abstract Submitted
A method for waking a transceiver for communicating directly with commodity Wi-Fi transceivers (TRXs) via backscatter modulation in an integrated tag device includes sensing an incident Wi-Fi-compliant wake-up signal with a wake-up stage. Upon wake-up, a payload packet is sensed with a sync stage, the sync stage having higher bandwidth and power than the wake-up stage, the sync stage enabling a backscatter transmission circuit in sync with the payload. A backscatter transceiver includes a wake-up receiver having an energy-detection based architecture and having circuitry to conduct a counter-based wake up responsive to two pre-specified WiFi compatible packets. A sync receiver is enabled by the wake-up receiver upon reception of the two pre-specified WiFi compatible packets, the sync receiver including circuitry to detect a payload packet and create a backscatter enable signal synced with a payload of the payload packet. A backscatter transmitter is enabled by the backscatter enable signal.
