Wireless Device Multi-Band Channel Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless local area networks, channel scanning by base stations often disrupts communication with connected wireless terminals, leading to disconnection issues due to the need to stop wireless communication on the channel being scanned.
Innovation Solution
A wireless device with processing circuitry that enables simultaneous connection to multiple frequency bands, allowing channel scanning on one band while maintaining connection on another, thereby minimizing communication disruption by sequentially scanning bands and switching to channels with better quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If channel scanning is performed on a wireless channel, then channel quality can be assessed and optimized, but wireless communication connection is disrupted causing disconnection
Solution Approach 1:
The patent divides the wireless communication system into multiple frequency bands (first band and second band). The access point performs channel scanning on the first band while maintaining communication connections on the second band, segmenting the scanning and communication functions across different bands to avoid connection disruption.
Solution Approach 2:
The access point performs channel scanning in advance on the first band before communication is needed, and maintains ready-to-use connections on the second band. This preliminary action allows the system to have alternative communication paths prepared before scanning disrupts the current band.
2Measurement precision
If channel scanning is performed to improve communication quality, then better channel selection is achieved, but communication disruption occurs during scanning
Solution Approach 1:
The patent segments communication functions across multiple frequency bands, allowing scanning operations on one band without interrupting communication on another band, thus maintaining productivity during quality optimization.
Solution Approach 2:
The access point maintains continuous communication through the second band while performing scanning on the first band. This ensures that the useful action of wireless communication continues uninterrupted even while channel quality assessment is performed.
3Reliability
If simultaneous connection using multiple bands is established, then communication continuity is maintained during scanning, but device complexity increases
Solution Approach 1:
The access point is designed with multi-functionality to handle multiple frequency bands simultaneously, serving both as a communication interface and a scanning interface across different bands. This universal design enables the single device to perform multiple functions without requiring separate dedicated hardware for each function.
