Solution Overview
Problem
In highly directional radio communication, such as millimeter-wave communication, users face challenges in clearly recognizing the communicable range and selecting the desired radio communication apparatus, as existing technologies limit the range and make it difficult to maintain communication when moving the apparatus outside the range.
Innovation Solution
A radio communication apparatus equipped with a peripheral-area imaging section to capture images using an optical system aligned with the line of sight for highly directional communication, a preview display section to show captured apparatus images, and a communication establishing section to establish and maintain radio communication with displayed apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If highly directional radio communication is used to improve communication stability, then communication reliability is improved, but the communicable range becomes limited and users cannot clearly recognize the range
Solution Approach 1:
An optical system (camera) is introduced as an intermediary to visually indicate the radio communication range. The camera captures images within the radio wave radiation angle range, and these images are displayed on a screen to show users the communicable area, thereby resolving the contradiction between directional stability and range recognition.
Solution Approach 2:
The patent uses visual display (color/image changes) to indicate the communicable range. By displaying captured images on a screen, users can visually perceive the radio communication range through color and image content, solving the problem of unclear range recognition in highly directional communication.
2Ease of operation
If flick operation on touch panel is used to simplify device operation, then ease of operation is improved, but the user cannot surely select a desired apparatus when multiple apparatuses are in the same direction
Solution Approach 1:
The optical system acts as an intermediary between the user's flick operation and the apparatus selection. By capturing images within the radio communication range and displaying them, the system provides visual feedback that helps users accurately identify and select the desired apparatus, thereby improving selection accuracy while maintaining operational simplicity.
Solution Approach 2:
The system provides visual feedback by displaying captured images on the screen. This feedback mechanism allows users to see which apparatuses are within the communicable range and make accurate selections, resolving the contradiction between simple operation and precise selection.
3Measurement precision
If highly directional radio communication is used to improve communication directionality, then communication precision is improved, but communication is interrupted when the user moves the apparatus outside the range
Solution Approach 1:
The optical system serves as a mediator to monitor and indicate the communicable range. By continuously capturing and displaying images within the radio wave radiation angle, the system provides real-time visual feedback about communication status, allowing users to understand when they are moving out of range and take appropriate actions to maintain communication continuity.

AI summary
Provided is a wireless communication apparatus wherein when a wireless communication having high directivity is performed together with another wireless communication apparatus, the user can clearly recognize a communicatable range of the wireless communication. In this apparatus, a periphery image capturing unit (110) captures a periphery image through the optical system in such a manner that the line-of-sight of wireless communication for establishing a wireless communication having high directivity is coincident with the optical axis of the optical system. A preview display unit (120) displays, in a preview window, another wireless communication apparatus image-captured as a periphery image. A communication establishing unit (130) establishes the wireless communication with the other wireless communication apparatus displayed in the preview window.
