Automated Radio Power Calibration for Multi-RAT Coverage Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-radio access technology (RAT) environments, especially with small-coverage base stations, there is a challenge in maintaining consistent signal quality due to varying power settings across different radio technologies, which can lead to interference and reduced service quality, particularly in areas with high building penetration loss.
Innovation Solution
An automated method for determining and applying power settings for one radio access technology based on the power settings of another, using an offset or function-based approach to match coverage areas, thereby mitigating interference and ensuring consistent service across different frequency bands and propagation profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual field testing and adjustment is used to calibrate power settings for each RAT, then coverage matching can be achieved, but deployment time and cost increase significantly
Solution Approach 1:
The system performs preliminary power calibration by automatically determining power settings for a first RAT based on power settings of a second RAT using stored offset values, before actual deployment. This preliminary automated calibration eliminates the need for time-consuming manual field testing and adjustment, while still achieving accurate coverage matching.
Solution Approach 2:
The system copies power calibration relationships between different RATs by storing and applying offset values that represent the power relationship between RATs. Instead of manually testing each RAT independently, the system copies the calibrated relationship from one RAT to another, significantly reducing deployment time while maintaining accuracy.
2Measurement precision
If manual field testing is performed to determine power settings, then accurate coverage matching can be achieved, but deployment cost increases
Solution Approach 1:
The system performs self-service power calibration by automatically determining power settings for one RAT based on power settings of another RAT using stored offset values. This automated self-calibration eliminates the need for expensive manual field testing and expert intervention, reducing deployment costs while maintaining calibration accuracy.
Solution Approach 2:
The system copies calibrated power relationships between RATs using stored offset values, avoiding the need for repeated expensive manual field testing. By copying the established power relationship from one RAT to another, the system achieves accurate coverage matching at a fraction of the original deployment cost.
3Productivity
If power settings are manually adjusted for each RAT independently, then individual RAT optimization is possible, but coverage inconsistency and interference occur
Solution Approach 1:
The system merges the power calibration processes of multiple RATs by establishing and applying power relationships between them. Instead of optimizing each RAT independently, the system combines their power settings using stored offset values, ensuring that coverage areas are consistent across RATs while eliminating interference through coordinated power management.
