Radio Wave Environment Display Using Maximum Intensity Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for displaying a radio wave environment fail to accurately represent the environment when multiple wireless transmitters transmit different radio waves, as they sum the received power from multiple transmitters, leading to meaningless results due to interference.
Innovation Solution
A radio wave environment display device and method that select the maximum intensity of received power and its arrival direction at each point in the area, allowing for a practical and interference-aware representation of the radio wave environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If received power from multiple transmitters is summed up, then the total signal strength is calculated, but the result becomes meaningless due to radio wave interference
Solution Approach 1:
The patent extracts only the maximum received power value from multiple transmitter signals at each measurement point, discarding other interfering signals. This selective extraction approach eliminates the problem of meaningless summation while preserving the most significant signal information for accurate coverage area representation.
2Ease of operation
If conventional display methods are used, then the display process is simple, but the radio wave environment cannot be appropriately displayed when multiple transmitters operate simultaneously
Solution Approach 1:
The patent applies local quality by determining the maximum received power independently at each measurement point location. This point-by-point evaluation ensures that the display accurately reflects the local radio wave environment characteristics, allowing appropriate representation even in complex multi-transmitter scenarios while maintaining operational simplicity.

AI summary
A radio wave environment display device includes a display unit that displays a radio wave environment and a controller. The radio wave environment display device displays a radio wave environment in an area where a plurality of wireless transmitters located at different positions transmit radio waves. The controller selects, at each of a plurality of points in the area, a maximum intensity among intensities that are magnitudes of received power of radio waves transmitted from the wireless transmitters and causes the display unit to display the radio wave environment at each of the plurality of points based on the maximum intensity selected and an arrival direction of a radio wave with the maximum intensity selected.
