Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of the 6 GHz band for wireless communication according to the IEEE 802.11 series standard can cause interference with existing wireless systems, such as fixed wireless communication and satellite communication.
Innovation Solution
A communication apparatus that includes determination means to identify signals outside the IEEE 802.11 series standard in the 6 GHz band and control means to prevent transmission of IEEE 802.11 series standard signals in affected frequency channels, thereby reducing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the 6 GHz band is used for IEEE 802.11 communication to improve throughput, then communication speed is improved, but interference with existing wireless systems occurs
Solution Approach 1:
The communication apparatus performs preliminary detection of the 6 GHz band frequency channel before communication to identify signals from other wireless systems. Based on this advance detection, the apparatus determines whether to allow IEEE 802.11 communication in the detected channel, preventing interference before it occurs.
Solution Approach 2:
A determination unit acts as an intermediary between the signal detection unit and the communication transmission. This determination unit evaluates detected signals and decides whether to permit or block IEEE 802.11 communication based on the presence of other wireless system signals, mediating between throughput desires and interference prevention.
2Object-affected harmful factors
If signal detection is performed in the 6 GHz band to reduce interference, then interference with other wireless systems is reduced, but communication efficiency may be reduced due to detection overhead
Solution Approach 1:
The apparatus performs signal detection selectively rather than continuously monitoring all 6 GHz band channels at all times. Detection is performed partially based on communication needs and conditions, balancing interference prevention with time efficiency.

AI summary
When a communication is performed in a particular frequency channel included in a 6 GHz band, if a signal that is not according to the IEEE 802.11 series standard is detected in the 6 GHz band, control is performed such that a signal according to the IEEE 802.11 series standard is not allowed to be transmitted in the particular frequency channel.
