BACKSCATTER-BASED POSITIONING - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240175965 titled 'BACKSCATTER-BASED POSITIONING
Simplified Explanation
The patent application describes a method of wireless communication that supports backscatter-based positioning. This involves transmitting a configuration signal to a tag device, followed by a positioning reference signal. The tag device then sends a backscatter signal based on the received signals.
- Wireless communication method supporting backscatter-based positioning:
- Transmit configuration signal with tag address and modulation scheme - Send positioning reference signal - Receive backscatter signal from tag device
Potential Applications
This technology could be applied in various industries such as logistics, inventory management, and asset tracking where precise positioning of objects is required.
Problems Solved
- Enables accurate positioning of objects without the need for complex infrastructure - Improves efficiency in tracking and locating items in real-time
Benefits
- Cost-effective solution for positioning applications - Low power consumption for extended battery life in devices - Simplifies implementation of location tracking systems
Potential Commercial Applications
Optimizing Supply Chain Management with Backscatter-Based Positioning Technology
Possible Prior Art
One example of prior art in this field is the use of RFID technology for tracking and identifying objects. However, the specific implementation of backscatter-based positioning as described in this patent application appears to be a novel approach.
What are the technical specifications of the modulation scheme used in the method described in the patent application?
The technical specifications of the modulation scheme used in the method are not provided in the abstract. Further details in the full patent application may elaborate on the specific modulation scheme employed.
How does the positioning reference signal (PRS) contribute to the accuracy of the backscatter-based positioning system?
The abstract does not delve into the specific role of the positioning reference signal (PRS) in enhancing the accuracy of the backscatter-based positioning system. Further information in the detailed description of the patent application may shed light on the significance of the PRS in improving positioning accuracy.
Original Abstract Submitted
this disclosure provides systems, methods, and devices for wireless communication that support backscatter-based positioning. in a first aspect, a method of wireless communication includes transmitting a configuration signal that indicates a tag address of a tag device and a modulation scheme for generation of a backscatter signal. the method also includes transmitting a positioning reference signal (prs) after transmission of the configuration signal. the method further includes receiving, from the tag device, a backscatter signal based on the modulation scheme and the prs. other aspects and features are also claimed and described.
