TECHNIQUES FOR IMPROVING RANGING BETWEEN ELECTRONIC DEVICES - A simplified explanation of the abstract
This abstract first appeared for US patent application 18668076 titled 'TECHNIQUES FOR IMPROVING RANGING BETWEEN ELECTRONIC DEVICES
The abstract of this patent application describes a method for a mobile device to calculate frequency offset for a wireless protocol by analyzing timestamps of ranging and response packets.
- The mobile device receives timestamps indicating sending and receiving times for packets.
- It calculates responder turn-around time and responding round trip time based on these timestamps.
- The device also receives initiator turn-around time and initiator round trip time from an electronic device.
- By using these times, the mobile device calculates a frequency offset for the wireless protocol.
- It compares the observed frequency offset to the calculated one to determine any differences and adjusts ranging measurements accordingly.
Potential Applications: - Wireless communication systems - IoT devices - Mobile devices with wireless capabilities
Problems Solved: - Improving accuracy in wireless communication - Enhancing synchronization between devices - Optimizing ranging measurements in wireless protocols
Benefits: - Increased efficiency in wireless data transmission - Better performance of wireless devices - Enhanced reliability of wireless networks
Commercial Applications: Title: "Enhancing Wireless Communication Efficiency with Frequency Offset Calculation" This technology can be utilized in various industries such as telecommunications, IoT, and consumer electronics to improve the performance and reliability of wireless communication systems.

Original Abstract Submitted
A mobile device may receive a plurality of timestamps, wherein the plurality of timestamps indicate sending and receiving time for ranging packets and response packets. The mobile device may calculate a responder turn-around time as a first difference between the second time and the first time. The mobile device may calculate a responding round trip time as a second difference between the second time and the third time. The mobile device may receive from the electronic device an initiator turn-around time and an initiator round trip time. The mobile device may calculate a frequency offset for the wireless protocol using the responder turn-around time, the responding round trip time, the initiator turn-around time, and the initiator round trip time. The mobile device may compare an observed frequency offset to the calculated frequency offset to determine a frequency offset difference and whether it exceeds a threshold, adjusting a ranging measurement.
