Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current indoor positioning technologies face challenges in achieving high-precision positioning due to the limited availability of multiple base stations within the same coverage area, which is often hindered by cost constraints.
Innovation Solution
A positioning method that utilizes a network device externally connected to N antennas, where N is greater than or equal to 3, to receive and process positioning signals from terminal devices, determining TOA and/or RSSI information, and sending this information to a service anchor for positioning, thereby eliminating the need for multiple network devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple base stations are deployed to achieve high-precision indoor positioning, then positioning accuracy is improved, but system cost increases
Solution Approach 1:
The patent combines multiple receive channels (at least 3) into a single network device, allowing the device to function as multiple virtual base stations. This merging approach enables multi-station joint positioning algorithms to be executed within one physical device, achieving high positioning accuracy without deploying multiple physical base stations, thus resolving the contradiction between positioning accuracy and system cost.
Solution Approach 2:
The network device is designed with multi-functional capabilities by integrating multiple receive channels that can independently process positioning signals. Each receive channel can be configured to simulate different base station functionalities, allowing a single device to perform the roles of multiple base stations, thereby reducing deployment costs while maintaining positioning precision.
2Measurement precision
If multiple network devices are used for multi-station joint positioning, then positioning performance is improved, but device complexity and cost increase
Solution Approach 1:
The patent merges multiple network devices into a single device by integrating multiple receive channels within one network device. This allows the system to execute multi-station joint positioning algorithms without requiring multiple physical devices, thereby improving positioning performance while reducing system complexity and configuration overhead.
Solution Approach 2:
The patent transitions from a spatial dimension solution (deploying multiple physical base stations in different locations) to a functional dimension solution (creating multiple virtual receive channels within one device). This dimensional shift allows the system to achieve multi-station positioning capabilities without the physical complexity of deploying multiple devices.

AI summary
A positioning method, a device, a system, a chip, and a storage medium are provided. A network device is externally connected to N antennas, the network device has N receive channels, and the N antennas are in a one-to-one correspondence with the N receive channels. The method includes: A network device receives, by using each of the N antennas, a positioning signal sent by a terminal device, determines TOA information and/or RSSI information of the positioning signal on each of the N receive channels, and sends the TOA information and/or the RSSI information of the positioning signal on each of the N receive channels to a service anchor. The service anchor is configured to position the terminal device based on the TOA information and/or the RSSI information.
