SSID Broadcast Management via Beacon Priority
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless networks face challenges in effectively managing and prioritizing multiple SSIDs, leading to inefficient connections between user devices and available networks, particularly in environments with multiple access points.
Innovation Solution
Implementing a system that allows wireless devices to prioritize network-associated identifiers (SSIDs) based on transmission parameters such as broadcast interval and power, ensuring preferred SSIDs are more likely to be selected by devices, without directly controlling user devices or service providers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple SSIDs are broadcast with equal priority, then all networks are equally accessible, but user devices cannot efficiently prioritize secure or preferred networks
Solution Approach 1:
The patent changes the transmission parameters of beacon frames by introducing a priority field that indicates the relative importance of each SSID. User devices use this priority information to preferentially connect to high-priority networks, resolving the contradiction between equal accessibility and preferred network connection.
2Area of stationary object
If SSIDs are broadcast at high transmission power, then network visibility is improved, but energy consumption increases and interference with other networks worsens
Solution Approach 1:
The patent applies different transmission power levels to different SSIDs based on their priority and local requirements. High-priority SSIDs can be transmitted at higher power for better visibility, while low-priority SSIDs use lower power to conserve energy and reduce interference, resolving the contradiction between coverage area and energy consumption.
3Speed
If beacon frames are transmitted frequently, then network discovery is faster, but channel occupancy increases and other networks suffer
Solution Approach 1:
The patent implements selective beacon transmission where only high-priority SSIDs transmit beacons frequently, while low-priority SSIDs transmit less frequently. This partial action approach allows fast network discovery for important networks while leaving channel capacity available for other networks, resolving the contradiction between discovery speed and channel availability.
4Adaptability or versatility
If user devices autonomously prioritize SSIDs without external control, then device independence is maintained, but coordinated network management is reduced
Solution Approach 1:
The patent enables user devices to autonomously prioritize SSIDs by incorporating priority information directly in the beacon frames. Devices use this information to make independent connection decisions without requiring external control systems, maintaining device independence while simplifying network coordination.

AI summary
Systems, methods, or apparatus may comprise a computing device to transmit a first plurality of beacon frames, where each beacon frame includes a first network identifier, and a second plurality of beacon frames, where each beacon frame includes a different second network identifier. Further, the computing device may also cause the wireless transceiver to transmit the first plurality of beacon frames using a transmission parameter, and transmit the second plurality of beacon frames using a different transmission parameter—that differs from the transmission parameter of the first plurality of beacon frames.
