Dynamic Frequency Selection for Seamless Bandwidth Upgrade
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless networking systems require Channel Availability Check (CAC) silence during the upgrade of channels from low bandwidth to high bandwidth, leading to poor user experience due to potential wireless disconnection.
Innovation Solution
A method and apparatus for implementing dynamic frequency selection, where a master network device is controlled to work at a first bandwidth, and then upgraded to a second bandwidth including a target channel only if it is not occupied by a non-target signal, such as a radar signal, without CAC silence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Channel Availability Check (CAC) silence is implemented during bandwidth upgrade, then radar signal detection reliability is improved, but wireless connection stability deteriorates due to potential disconnections
Solution Approach 1:
The system performs preliminary radar signal detection and channel availability assessment before initiating bandwidth upgrade, so that the upgrade can proceed without CAC silence interruption. The master network device checks whether the target channel is occupied by radar signals in advance, and only initiates the upgrade when the channel is confirmed available, thereby avoiding disconnections during the upgrade process.
2Measurement precision
If CAC silence is required during bandwidth upgrade, then channel availability verification is ensured, but user experience deteriorates due to wireless disconnection
Solution Approach 1:
The master network device performs channel availability verification before initiating bandwidth upgrade by checking if the target channel is occupied by radar signals. This preliminary verification ensures that the upgrade can proceed without interrupting CAC operations, thereby maintaining both measurement precision and user experience without wireless disconnections.
3Manufacturing precision
If real-time channel monitoring is implemented, then dynamic bandwidth adjustment accuracy is improved, but system complexity increases
Solution Approach 1:
The master network device autonomously performs real-time monitoring of the target channel for radar signals and automatically adjusts the bandwidth based on detection results. The system self-manages the monitoring and adjustment process without requiring external intervention or complex control mechanisms, thereby achieving high adjustment accuracy while keeping system complexity manageable.

AI summary
The disclosure provides a method and apparatus for implementing dynamic frequency selection. The method is applied to a wireless networking system, where the wireless networking system includes a master network device, and the method includes: controlling the master network device to work at a first bandwidth; monitoring in real time whether a target channel is occupied by a first non-target signal; and controlling, under a condition that the target channel is not occupied by the first non-target signal, the master network device to work at a second bandwidth including the target channel. The first bandwidth is upgraded to the second bandwidth under the condition that the target channel is not occupied by the first non-target signal. The bandwidth is upgraded without Channel Availability Check (CAC) silence. A high wireless connection rate is provided while user experience is guaranteed.
