METHOD AND APPARATUS FOR DEVICE-BASED INDOOR POSITIONING USING WI-FI FINE TIMING MEASUREMENTS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18325896 titled 'METHOD AND APPARATUS FOR DEVICE-BASED INDOOR POSITIONING USING WI-FI FINE TIMING MEASUREMENTS
Simplified Explanation
The patent application describes a method for determining the position of a device using fine-time measurement (FTM)-enabled Wi-Fi nodes. Here are the key points:
- Scanning is performed to identify FTM-enabled Wi-Fi nodes and create a list of these nodes.
- A ranging operation is conducted by selecting nodes from the list and processing their ranging responses to measure the distance.
- Based on the distance measurements obtained from the ranging operation, the position of the device is estimated.
Potential Applications
This technology has potential applications in various fields, including:
- Indoor navigation systems: The method can be used to accurately determine the position of a device within indoor environments, where GPS signals may be weak or unavailable.
- Asset tracking: It can be utilized to track the location of assets within a facility or warehouse, enabling efficient inventory management.
- Location-based services: The technology can enhance location-based services by providing more precise positioning information to users.
Problems Solved
The method addresses the following problems:
- Limited accuracy of traditional Wi-Fi positioning: By utilizing FTM-enabled Wi-Fi nodes and conducting ranging operations, the method improves the accuracy of Wi-Fi-based positioning systems.
- Inadequate indoor positioning solutions: The technology offers a solution for accurate indoor positioning, where other methods like GPS may not be effective.
- Tracking assets in complex environments: By estimating the position of a device based on distance measurements, the method enables efficient tracking of assets within complex indoor environments.
Benefits
The use of this technology provides several benefits:
- Improved accuracy: By leveraging FTM-enabled Wi-Fi nodes and distance measurements, the method offers higher accuracy in determining the position of a device.
- Cost-effective solution: The method utilizes existing Wi-Fi infrastructure, eliminating the need for additional hardware or infrastructure investments.
- Versatile application: The technology can be applied in various scenarios, such as indoor navigation, asset tracking, and location-based services, providing flexibility and adaptability.
Original Abstract Submitted
A method includes scanning for registered fine-time measurement (FTM)-enabled Wi-Fi nodes to generate a list of the FTM-enabled Wi-Fi nodes. The method also includes performing a ranging operation by (i) selecting nodes to range with from the list of the FTM-enabled Wi-Fi nodes and (ii) processing ranging responses from the selected nodes to generate distance measurements. The method further includes estimating a position of a device based on the distance measurements generated from the ranging operation.
