Positioning Network Signal Layout for Lower Base Station Density

Solution Overview

Problem

Current positioning technologies face challenges in providing high-precision indoor and urban area positioning due to increased base station layout density and networking costs, particularly in environments with dense commercial activity and tall buildings, where existing methods like GPS, WiFi, and UWB struggle with synchronization errors and complex signal transmission.

Innovation Solution

A method and device for a positioning network that determines networking modes based on application scenarios, allowing for independent or joint networking of positioning and communication networks, configuring positioning base stations to send positioning signals and synchronization signals independently or jointly with communication base stations, reducing the need for dense base station layouts.

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments signal transmission by allowing base stations to selectively send either positioning reference signals or synchronization signals based on configuration, rather than requiring all base stations to send all signal types. This reduces transmission complexity while maintaining synchronization performance through coordinated signal distribution across the network.
