Communication Device Access Point Detection for Stable Frequency Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication devices in mobile objects face interruptions and frequency changes when attempting to communicate with multiple targets in different frequency bands due to overlapping frequency bands, particularly when connecting with access points without permission.
Innovation Solution
A communication device with a communication unit, access point detection unit, and communication control unit that displays access point information differently for each frequency band, allowing the occupant to select a non-overlapping frequency band to maintain communication with the terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the communication device communicates with multiple targets in different frequency bands simultaneously, then the communication capability is improved, but the communication with communication terminal is interrupted or frequency is changed by access point connection
Solution Approach 1:
The patent segments access points into two categories: first access points in the first frequency band that can cause interference, and second access points in the second frequency band that do not interfere. The display device separately presents these two types of access points, allowing the user to selectively connect to non-interfering access points while maintaining communication with the communication terminal.
2Ease of operation
If the communication device connects to access points in the first frequency band, then the access point connection is established, but the communication with communication terminal is interrupted
Solution Approach 1:
The patent performs preliminary detection and classification of access points before connection. The display device presents information about first access points (which would cause interruption) and second access points (which would not cause interruption) separately, allowing the user to make an informed decision and connect to appropriate access points in advance, avoiding communication interruptions.
3Ease of operation
If the communication device allows connection to any detected access point, then the ease of connection is improved, but the frequency changes without permission during communication
Solution Approach 1:
The patent applies local quality by providing different information presentation for different types of access points. Second access points (in the second frequency band) are presented with information indicating they will not cause frequency changes or interruptions, while first access points are presented differently to warn of potential issues. This allows users to easily connect to safe access points while avoiding problematic ones.

AI summary
A communication device includes: a communication unit configured to perform wireless communication; an access point detection unit configured to detect access points capable of communication connection with the communication unit; and a communication control unit configured to display an access point information image on a display device when communication between the communication unit and a communication terminal is performed in a first frequency band, the access point information image presenting information on the access points detected by the access point detection unit, with a first access point capable of communication connection in the first frequency band being presented differently from a second access point capable of communication connection in a second frequency band.
