Master-Slave Network Management Frame Antenna Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing master-slave network systems fail to ensure optimization of signal coverage across an entire management area managed by a master device, as they adjust management frame antennas based solely on currently connected user devices rather than considering overall signal quality.
Innovation Solution
A method where the master device instructs slave devices to monitor signal quality using each antenna group, collects and analyzes this information to select optimal management frame antennas for each slave device, ensuring comprehensive signal coverage by determining antenna groups with the highest accumulated signal quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the AP adjusts the management frame antenna according to the currently connected UDs, then the signal coverage for connected users is improved, but the optimization of the entire management area cannot be ensured
Solution Approach 1:
The patent segments the management area into multiple monitoring zones, each monitored by different slave devices. Each slave device independently monitors signal quality in its designated zone and reports to the master device, enabling comprehensive area optimization while maintaining local connectivity reliability
Solution Approach 2:
The patent introduces a new dimension of optimization by considering signal quality from multiple slave devices simultaneously. Instead of optimizing based on a single AP-UD connection, the system evaluates accumulated signal quality across multiple dimensions (multiple slave devices, multiple antenna groups) to select the optimal management frame antenna
2Measurement precision
If multiple slave devices monitor signal quality using each antenna group, then the selection accuracy for management frame antennas is improved, but the system complexity increases
Solution Approach 1:
The patent merges the monitoring functions of multiple slave devices into a unified decision-making process at the master device. The master device collects signal quality information from all slave devices and antenna groups, then performs centralized analysis to select the optimal management frame antenna, reducing individual device complexity while maintaining high measurement precision
Solution Approach 2:
The patent creates a universal monitoring framework where each slave device performs the same signal quality monitoring function across different antenna groups. This multi-functional approach allows the system to gather comprehensive data without requiring specialized hardware for each monitoring task, thereby managing complexity

AI summary
A method for selecting a management frame antenna based on a master-slave network and an apparatus are provided. In one example method, when a preset condition is met, a signal quality collection instruction is sent by a master device to a first slave device and a second slave device, so as to receive returned signal quality information. A management frame antenna is selected for the first slave device and a management frame antenna for the second slave device according to the received signal quality information, so that the selected management frame antennas can implement signal coverage optimization in an entire area managed by the master device.
