Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face issues with beacon transmission failures, leading to extended idle times and disconnections in wireless devices due to signal collisions and instability in Wi-Fi networks.
Innovation Solution
A beacon adjustment method and device that detects signal collisions and adjusts beacon transmission times or timing synchronization functions based on detected signals and collision events to prevent collisions and ensure stable beacon transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beacon transmission is performed at fixed intervals, then timing synchronization is maintained, but signal collisions occur causing transmission failures
Solution Approach 1:
The patent applies dynamics by making the beacon transmission time adjustable rather than fixed. The system dynamically modifies the beacon transmission time based on detected signal collision patterns, transforming a static timing mechanism into an adaptive one that responds to environmental conditions and avoids collisions while maintaining synchronization.
Solution Approach 2:
The patent implements feedback by detecting signal collision events and using this information to adjust future beacon transmission times. The system continuously monitors for collisions, calculates adjustment bases from detected patterns, and modifies transmission timing accordingly, creating a closed-loop control system that improves reliability through learned adaptations.
2Reliability
If beacon transmission time is adjusted to avoid collisions, then transmission reliability improves, but timing synchronization may be affected
Solution Approach 1:
The patent applies parameter changes by systematically modifying the beacon transmission time parameter based on detected collision patterns. Rather than arbitrary adjustments, the system calculates specific time offsets from detected signal characteristics, changing the transmission parameter in a controlled manner that maintains synchronization while avoiding collisions.
Solution Approach 2:
The patent implements preliminary action by detecting signal patterns and calculating adjustment bases before actual beacon transmission occurs. The system proactively identifies potential collision scenarios and pre-adjusts transmission timing based on detected patterns, preventing collisions before they happen rather than reacting after failures occur.

AI summary
A beacon adjustment method is applied in a wireless access point (AP). The beacon adjustment method includes following steps: detecting at least one signal or at least one signal collision event; calculating an adjustment base according to the at least one signal or the at least one signal collision event; and adjusting a target beacon transmission time (TBTT) according to the adjustment base, or adjusting a timing value of a timing synchronization function (TSF) according to the adjustment base.
