Crossed Antenna Feed Detection in Co-Sited Base Stations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation and maintenance of base stations in wireless telecommunications networks are complex and prone to errors, particularly crossed antenna feeds, which can lead to compromised network performance and are difficult to detect, often manifesting as poor network behavior without clear root-cause identification.
Innovation Solution
A method and system that utilize direction information and handover data to identify crossed antenna feeds by selecting co-sited cells, determining neighbor cell locations relative to antenna pointing directions, calculating crossed antenna feed scores, and reconnecting antenna feeds to correct assignments, thereby automating the detection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional drive tests are used to detect crossed antenna feeds, then detection capability is provided, but cost and time consumption increase significantly
Solution Approach 1:
The patent replaces the mechanical drive test system with an automated electronic detection system that uses network measurement data, handover information, and direction data to identify crossed antenna feeds through algorithmic analysis rather than physical testing
Solution Approach 2:
The patent creates a virtual model of the antenna feed configuration and compares it against actual network performance data and measured directions, allowing detection without physical drive tests by analyzing correlated network parameters
2Productivity
If automated detection systems are implemented, then productivity increases, but device complexity increases
Solution Approach 1:
The patent integrates multiple detection functions into a single automated system that simultaneously analyzes network measurement data, handover information, and direction data to perform comprehensive crossed antenna feed detection without requiring separate specialized systems
Solution Approach 2:
The patent combines previously separate detection methods and data sources into one unified automated detection process that correlates multiple parameters together to identify crossed antenna feeds, reducing the need for multiple independent systems

AI summary
A method for a cellular telecommunications network includes selecting first and second source cells that are co-sited cells associated with first and second antennas, respectively, identifying first neighbor cells of the first cell and second neighbor cells of the second cell, determining that an antenna feed for the second cell is feeding the first antenna by comparing locations of the first neighbor cells to a pointing direction of the first antenna.
