Solution Overview

Problem

Current techniques for generating coverage maps in telecommunications do not accurately represent real-world conditions, as they fail to account for obstructions like buildings and trees, leading to less than accurate coverage information.

Innovation Solution

The solution involves collecting and aggregating data from devices connected to a service provider's network to generate coverage maps that reflect real-world conditions, using user data to verify signal strength and quality, and presenting this information through user interfaces such as maps, graphs, or charts for improved accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If engineering estimates and prediction models are used to generate coverage maps, then coverage information can be obtained without extensive field testing, but the accuracy of coverage information deteriorates because real-world obstructions like buildings and trees are not accounted for

Engineering Contradiction:
Improvetime for coverage verificationVSAvoidcoverage information accuracy
Core Design Contradiction:
Loss of timeVSMeasurement precision

Solution Approach 1:

The system collects actual signal strength measurements from user devices in the field and uses this feedback data to verify and update coverage map predictions. The coverage verification module compares predicted coverage with actual measurements, creating a closed-loop system that continuously improves accuracy based on real-world performance data.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

User devices automatically contribute signal strength measurements and location data to the coverage verification system without requiring dedicated field testing equipment. The system leverages the existing network of user devices to gather coverage data, turning end-users into passive participants in coverage verification.

Inventive Principle:
Principle #25Self-service

2Productivity

If traditional prediction models are used, then coverage maps can be generated quickly without extensive data collection, but the reliability of coverage information deteriorates due to lack of real-world condition consideration

Engineering Contradiction:
Improvecoverage map generation speedVSAvoidcoverage information reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system first generates coverage predictions using engineering models before field verification. This preliminary coverage map serves as a hypothesis that is then tested against actual measurements, allowing the system to maintain quick initial generation while subsequently improving reliability through verification.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Actual signal measurements from user devices provide feedback that validates or corrects the preliminary prediction models. The system uses this feedback to identify areas where predictions diverge from reality, improving the reliability of future predictions while maintaining efficient generation speeds.

Inventive Principle:
Principle #23Feedback

3Use of energy by moving object

If engineering estimates are used for coverage determination, then resource consumption is reduced, but the quality of service information deteriorates due to inability to account for real-world signal blocking

Engineering Contradiction:
Improveenergy for coverage verificationVSAvoidsignal strength measurement accuracy
Core Design Contradiction:
Use of energy by moving objectVSMeasurement precision

Solution Approach 1:

The system leverages the computational resources and sensing capabilities of user devices themselves to collect and report signal strength data. This eliminates the need for dedicated field testing equipment and reduces overall energy consumption while maintaining measurement accuracy through distributed data collection.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system uses feedback from actual device measurements to correct engineering estimates. By comparing predicted signal strength with actual measurements from multiple devices, the system can identify patterns of signal blocking by buildings and trees, improving accuracy without proportionally increasing energy consumption.

Inventive Principle:
Principle #23Feedback
