Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a reliable method to validate radio operations at 5G cell sites during post-construction to ensure proper functionality and prevent potential obstacles before commissioning, as existing validation methods are inadequate in ensuring the reliability and operability of these sites.
Innovation Solution
A mobile testing system that includes a processing device executing testing software to validate radio operations by capturing and analyzing downlink transmits, determining positional information, and performing tests such as power-up validation, voltage standing wave ratio measurement, and antenna coupling checks, ensuring that radio operations meet specified standards without alarms or mismatches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional validation methods are used at 5G cell sites, then the commissioning process can proceed, but reliability and operability issues may arise after deployment
Solution Approach 1:
The patent performs validation tests before commissioning the 5G cell site. The system executes a series of tests including power-up validation, VSWR measurement, antenna coupling verification, and radio operation validation to identify and correct issues before deployment, preventing post-construction failures.
Solution Approach 2:
The system provides real-time feedback during validation by comparing measured parameters (VSWR, signal strength, positional information) against expected values. The system generates validation reports that indicate pass/fail status and provides diagnostic information to guide corrective actions.
2Reliability
If comprehensive validation tests are performed, then radio operation reliability is improved, but the complexity of the validation system increases
Solution Approach 1:
The validation system is designed to perform multiple functions using a single integrated platform. It can conduct power-up validation, VSWR measurement, antenna coupling checks, radio operation validation, and positional verification, reducing the need for multiple separate testing devices and procedures.
Solution Approach 2:
The system automatically performs validation tests and generates reports without requiring extensive manual intervention. The automated testing reduces the skill level and time required from validation personnel while maintaining comprehensive testing coverage.
3Manufacturing precision
If multiple validation tests are conducted, then manufacturing precision of radio operations is improved, but the duration of the validation process increases
Solution Approach 1:
The system performs critical validations early in the commissioning process before full deployment. By validating power-up, basic radio operations, and antenna coupling beforehand, the system prevents the need for rework after deployment, ultimately reducing total validation time despite the comprehensive nature of individual tests.
Solution Approach 2:
The validation process is designed to continue efficiently through multiple test stages. The system maintains continuous operation by automatically proceeding through validation sequences and only pausing when corrections are required, maximizing the use of validation time for productive testing rather than repeated manual setup.

AI summary
An example method of testing a cell site includes capturing a transmission from a radio at the cell site on a mobile device located at the cell site, receiving position data on the mobile device while capturing the transmission, and verifying that the position data identifies the cell site on the mobile device. The mobile device receives a signal from the radio at the cell site at a frequency and validates a measurement of a voltage standing wave ratio (VSWR) of the signal at the frequency. The mobile device validates a power up of the radio at the cell site without detecting an alarm, and the mobile device validates that a connection on a port of an antenna at the cell site is coupled to a low-band connection or a high-band connection.
