METHOD AND DEVICE FOR PROVIDING SERVICE USING UWB COMMUNICATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18349507 titled 'METHOD AND DEVICE FOR PROVIDING SERVICE USING UWB COMMUNICATION
Simplified Explanation
The abstract describes a method for providing a service using ultra-wide band (UWB) communication. The method involves a UWB device receiving messages from initiator and responder anchors, and performing downlink time difference of arrival (DL-TDoA)-based localization.
- The UWB device receives a first UWB message from an initiator anchor, which initiates a ranging procedure.
- The UWB device receives a plurality of second UWB messages from a plurality of responder anchors in response to the first UWB message.
- The UWB device receives a third UWB message from the initiator anchor in response to the second UWB message.
- The UWB device receives a plurality of fourth UWB messages from the responder anchors in response to the third UWB message.
- The UWB device performs DL-TDoA-based localization using the first, second, third, and fourth UWB messages.
Potential applications of this technology:
- Indoor positioning and tracking systems: The DL-TDoA-based localization can be used to accurately determine the position of UWB devices in indoor environments, enabling applications such as asset tracking, navigation, and location-based services.
- Smart homes and buildings: UWB communication can be utilized for various smart home and building applications, including security systems, energy management, and automation.
- Industrial automation: UWB-based localization can be employed in industrial settings for tracking and monitoring equipment, optimizing workflows, and improving safety.
Problems solved by this technology:
- Accurate localization: The DL-TDoA-based localization method improves the accuracy of positioning systems, especially in indoor environments where GPS signals may be weak or unavailable.
- Multi-anchor communication: The method allows for efficient communication between initiator and responder anchors, enabling precise ranging and localization.
- Robustness in crowded environments: UWB communication is less susceptible to interference from other wireless devices, making it suitable for use in crowded environments where multiple devices are present.
Benefits of this technology:
- High accuracy: The DL-TDoA-based localization method provides high accuracy in determining the position of UWB devices, allowing for precise tracking and localization.
- Low power consumption: UWB devices typically have low power requirements, making them energy-efficient and suitable for battery-powered applications.
- Robust communication: UWB communication is robust and reliable, even in challenging environments with obstacles and interference.
- Scalability: The method can be scaled to support a large number of UWB devices, making it suitable for deployment in various scenarios and applications.
