Communication Apparatus Speech Detection Wireless LAN Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication apparatuses face radio interference issues when using the same frequency band for wireless communications, degrading the quality of digital cordless and wireless LAN communications, particularly due to the close proximity of digital cordless and wireless LAN communication modules.
Innovation Solution
A communication apparatus with a speech detecting portion that interrupts wireless communication by the wireless LAN portion when the user at the digital cordless communication apparatus is speaking, based on audio data analysis, to minimize radio interference and maintain communication quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the communication apparatus simultaneously makes wireless communications using the same frequency band for both digital cordless and wireless LAN portions, then communication productivity is improved, but radio interference degrades communication quality
Solution Approach 1:
The patent applies dynamics by making the wireless LAN communication dynamically controllable based on speech detection. The communication control portion adjusts the operation state of the wireless LAN communication portion in real-time according to whether speech is detected in the digital cordless communication, allowing the system to adapt between simultaneous communication mode and interference-avoidance mode.
Solution Approach 2:
The patent changes the operational parameter of the wireless LAN communication portion from continuous operation to conditional operation. By detecting speech presence and using this information to control the wireless LAN communication portion's operation state, the system modifies communication parameters dynamically to balance productivity and quality.
2Productivity
If the digital cordless communication portion and wireless LAN communication portion operate simultaneously in the same frequency band, then communication efficiency is improved, but radio interference increases particularly for the digital cordless portion
Solution Approach 1:
The patent converts the harmful effect of speech detection into a beneficial control mechanism. The speech detecting portion detects speech presence to determine when the wireless LAN communication portion should be interrupted, transforming the detection function into a useful control signal that protects the digital cordless communication from interference.
Solution Approach 2:
The communication control portion acts as an intermediary between the two communication portions. It receives speech detection information and uses it to mediate the operation of the wireless LAN communication portion, controlling when it operates and when it is interrupted to protect the digital cordless communication.
3Reliability
If the wireless LAN communication portion is interrupted when speech is detected, then communication quality for digital cordless is improved, but communication time for wireless LAN is reduced
Solution Approach 1:
The patent applies partial action by interrupting the wireless LAN communication portion only partially - specifically only when speech is detected - rather than continuously interrupting it. This selective interruption approach protects communication quality during critical periods while allowing wireless LAN communication to proceed during non-speech periods.
Data Source
AI summary
There is disclosed a communication apparatus including a first communication portion, a second communication portion, a speech detecting portion, and a communication control portion. The first communication portion wirelessly sends and receives audio data to and from a first other communication apparatus. The second communication portion wirelessly sends and receives general data to and from a second other communication apparatus. The speech detecting portion detects that a user at the first other communication apparatus is speaking. The communication control portion interrupts the wireless communication implemented by the second communication portion when the user at the first other communication apparatus is speaking.
