Wireless Base Station Location Detection Using Transponder Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for determining the location of wireless base stations in wireless network environments face challenges, particularly when GPS signals are blocked by buildings, and manual location determination is tedious and time-consuming, especially when the base stations move within or outside the building.
Innovation Solution
The implementation of a system using multiple transponders that receive and convert GPS satellite signals into transponder signals at different carrier frequencies, allowing the wireless base station to determine its location through time division multiplexing and synchronization with reference stations, enabling accurate location determination even in GPS signal-blocked areas and facilitating efficient allocation of wireless channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If GPS technology is used to determine location of wireless base station, then location determination is automated, but GPS signals are blocked by buildings making location determination unreliable
Solution Approach 1:
The patent introduces transponders as intermediary devices installed within buildings to receive GPS signals outdoors and retransmit them indoors. These transponders act as mediators that bridge the gap between GPS satellites and indoor base stations, allowing location determination to function reliably even when direct GPS signals are blocked by building structures.
2Loss of information
If manual generation and storage of location information is performed by Certified Professional Installer, then location information can be stored in wireless station, but the process is tedious and time consuming
Solution Approach 1:
The patent enables wireless base stations to automatically determine their own locations by receiving transmitted location information from transponders. This self-service mechanism eliminates the need for manual configuration by Certified Professional Installers, allowing base stations to autonomously acquire and store their location data, thereby saving significant installation time and reducing manual labor.
3Adaptability or versatility
If wireless base station moves from one location to another, then operational flexibility is improved, but manual generation of location information is required again
Solution Approach 1:
The patent enables mobile base stations to automatically receive and update their location information from transponders at new locations without requiring manual reconfiguration. When a base station moves, it can autonomously acquire location data from nearby transponders, maintaining operational flexibility while eliminating the time-consuming manual reconfiguration process that would otherwise be required.
4Measurement precision
If multiple transponders are deployed to provide location signals in GPS-blocked areas, then location determination accuracy is improved, but device complexity increases
Solution Approach 1:
The patent divides the location determination function into multiple independent transponder units distributed throughout the service area. Each transponder independently receives GPS signals and transmits location information, allowing the system to achieve high location determination accuracy through multiple signal sources while maintaining manageable complexity through modular, distributed architecture rather than a centralized complex system.

Function Achieved in This Case
This solution provides a reliable and efficient method for determining the location of wireless base stations within buildings and allocating wireless channels, ensuring accurate positioning and preventing interference, even when GPS signals are unavailable, thereby improving operational efficiency and reducing manual intervention.
Implementation Method 1
The first transponder converts the first wireless satellite signal into a first wireless transponder signal. The first transponder transmits the first wireless transponder signal at a second carrier frequency.
Data Source
AI summary
A wireless base station (such as disposed in a building) synchronizes itself with each of multiple reference stations in a network environment that transmit wireless signals. The wireless base station receives the wireless signals from the multiple reference stations. Based on timing of the received wireless signals, the wireless base station determines its location in a building with respect to the multiple reference stations. The determined location is then used as a basis to notify an allocation management resource of a location of the wireless base station for allocation of one or more wireless channels.
