Solution Overview
Problem
Current 5G positioning technologies lack accuracy for indoor and outdoor localisation of objects, are costly, and face interference from metallic surfaces, while existing UWB and Bluetooth LE systems have limitations in data privacy and absolute positioning.
Innovation Solution
A system utilizing simultaneous localisation and mapping (SLAM) with 5G communication, combined with Ultra Wide Band (UWB) and Bluetooth Low Energy (BLE) technologies, to accurately localise objects within a facility, employing ID tags for passive objects and 5G transceivers for active objects, while ensuring data privacy through encrypted communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If 5G positioning is used alone, then coverage area is improved, but localisation accuracy deteriorates
Solution Approach 1:
The patent combines 5G positioning with SLAM (Simultaneous Localization and Mapping) technology to achieve both wide coverage and high accuracy. The 5G network provides broad coverage while SLAM algorithms process sensor data from multiple sources to deliver precise localization, effectively merging the strengths of both systems to resolve the contradiction between coverage area and localization accuracy.
Solution Approach 2:
The patent introduces intermediate processing layers including edge computing nodes and cloud platforms that mediate between the 5G positioning data and final localization results. These intermediaries enhance accuracy through multi-layer data processing, fusion with other sensor data, and sophisticated algorithmic refinement without limiting the broad coverage provided by 5G.
2Measurement precision
If UWB/BLE localisation is used, then localisation accuracy is improved, but cost increases
Solution Approach 1:
The patent creates a multi-functional positioning system where a single infrastructure supports multiple technologies (5G, SLAM, and optional UWB/BLE). This universal system can adapt to different accuracy and cost requirements by selecting appropriate technology combinations, making high-accuracy UWB/BLE available only where necessary while using more cost-effective 5G+SLAM elsewhere.
Solution Approach 2:
The patent applies different localization technologies to different spatial zones and application scenarios within the facility. High-accuracy UWB/BLE is deployed only in areas requiring precision localization, while 5G+SLAM provides cost-effective coverage in other areas, optimizing the overall cost-accuracy balance through localized technology selection.
3Measurement precision
If 5G transceivers are equipped on passive objects, then localisation accuracy is improved, but device complexity and cost increase
Solution Approach 1:
Instead of equipping passive objects with complex 5G transceivers, the patent inverts the approach by using active user equipment (smartphones, tablets) to detect and localize passive objects. The passive objects can be tagged with simple identifiers, while the active devices perform the complex signal processing and localization calculations, thereby reducing device complexity on passive objects.
Solution Approach 2:
The system enables active user equipment to autonomously perform localization of passive objects without requiring the passive objects to have complex transceivers. The active devices self-service by processing signals, running SLAM algorithms, and determining positions, thereby simplifying the passive object design while maintaining high localization accuracy.
