WiFi Management Frame for Smart Device Network Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
WiFi-type smart devices without screens face challenges in accessing networks due to the need for manual entry of SSID and passwords, leading to lengthy data packet transmission processes and complex fault-tolerant algorithms, as well as multicast compatibility issues.
Innovation Solution
Generating and sending management frames carrying WiFi networking information, such as feature codes, SSIDs, and passwords, through direct connections using WiFi direct technology, allowing for efficient data transfer and reduced technological complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If UDP data packets are sent one by one to transmit WiFi networking information, then the information can be transmitted, but the sending time becomes excessively long
Solution Approach 1:
The patent merges multiple data packets into a single management frame. Instead of sending multiple separate UDP packets to convey WiFi networking information (SSID, password, etc.), the invention consolidates all necessary information into one management frame that can be transmitted in a single packet, thereby dramatically reducing transmission time while ensuring complete information delivery.
2Loss of information
If multiple data packets are sent to transmit WiFi networking information, then the information can be complete, but the technological complexity increases due to fault-tolerant algorithm requirements
Solution Approach 1:
The patent combines all WiFi networking information (including SSID, password, and other parameters) into a single management frame structure. This eliminates the need for complex fault-tolerant algorithms that would be required to reassemble information from multiple packets, significantly reducing technological complexity while maintaining information completeness.
3Productivity
If multicast data packets are used to transmit WiFi networking information, then the transmission efficiency improves, but multicast compatibility problems occur with certain routers
Solution Approach 1:
The patent introduces a management frame as an intermediary structure that carries WiFi networking information. Instead of using multicast data packets that may be blocked by routers with IGMP Snooping enabled, the invention uses this intermediary management frame that can be transmitted through standard unicast or broadcast channels, ensuring compatibility with all router configurations while maintaining efficient information transmission.

AI summary
A method for sending and acquiring WiFi networking information including generating, by a first WiFi-type smart device, a management frame that carries WiFi networking information; sending the management frame to be monitored by a second WiFi-type smart device; monitoring, by the second WiFi-type smart device, the management frame sent by the first WiFi-type smart device; and parsing the management frame to obtain the WiFi networking information, so that a network may be accessed by using the obtained WiFi networking information. The techniques of the present disclosure may reduce the time delay and technological complexity of a WiFi-type smart device in accessing a network.
