Signal Transmission Adjustment via Elevation Angle Trend Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Relative movement between mobile communication devices and communication nodes can reduce the line of sight, leading to unsuccessful signal transmission, as existing technologies do not effectively adapt to changing elevation angles and signal strengths between available communication nodes.
Innovation Solution
An electronic device determines trends in elevation angles between communication nodes and switches to a node with improving line of sight and higher signal strength, using processing circuitry to adjust transmission to ensure successful signal delivery.

Engineering Contradiction Analysis
1Reliability
If the mobile communication device transmits signals to a communication node, then data communication is achieved, but relative movement between the device and communication node reduces line of sight and signal reception reliability
Solution Approach 1:
The system performs preliminary actions by monitoring elevation angle trends and proactively switching to alternative communication nodes before the current node's signal quality deteriorates below acceptable thresholds. This predictive switching based on trend analysis prevents communication failures rather than reacting to them after they occur.
Solution Approach 2:
The system dynamically adapts communication node selection based on changing relative positions and elevation angles. Instead of using a static communication node, the system continuously evaluates multiple nodes and switches between them as conditions change, making the communication system flexible and adaptive to movement.
2Reliability
If the mobile communication device switches communication nodes frequently to maintain line of sight, then signal reception reliability improves, but device complexity and computational requirements increase
Solution Approach 1:
The system calculates trends of elevation angles in advance and uses these trends to predict future signal quality. By performing this trend analysis proactively, the system can make informed switching decisions without needing complex real-time signal quality monitoring and reaction mechanisms.
Solution Approach 2:
The system uses the mobile device's existing position information and elevation angle measurements to autonomously determine communication node switching decisions. The device self-manages the complexity of monitoring multiple nodes and determining optimal switching timing without requiring external control or complex coordination infrastructure.

AI summary
An electronic device includes a transmitter and processing circuitry. The processing circuitry determines trends of positions (e.g., elevation angles) of communication nodes and compare the trends of the positions. Based on the comparison between the trends of the positions, the processing circuitry selects a communication node for communication and uses the transmitter to transmit a signal to the selected communication node.
