Wi-Fi Terminal Channel Setup Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Wi-Fi terminal systems require user intervention during channel setup, leading to delays and inability to perform other functions during the process, and lack automatic recovery from setup failures.
Innovation Solution
A system and method for Wi-Fi terminals that automatically select a receiving terminal, generate a PIN code, and establish a Wi-Fi channel without user intervention, allowing other functions to be performed during setup and enabling automatic recovery from channel setup failures by using a Probe Request message and timers to manage the setup process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual channel setup procedure is used, then channel establishment can be completed, but user cannot perform other operations during setup and setup may fail without automatic recovery
Solution Approach 1:
The system performs preliminary actions by automatically generating PIN codes and preparing channel setup parameters before user initiation. The receiving terminal pre-listens for probe requests and pre-generates response messages, enabling the setup process to commence immediately without manual intervention delays.
Solution Approach 2:
The system implements self-service through automatic channel setup execution. After user selection of a receiving terminal, the sending terminal automatically generates PIN codes, sends probe requests, and completes the setup procedure without requiring user input. The receiving terminal automatically responds to probe requests and completes authentication, making the entire process autonomous.
2Productivity
If automatic channel setup is implemented, then setup speed increases and multitasking is enabled, but system complexity increases
Solution Approach 1:
The system uses standardized Wi-Fi protocol messages (probe requests, probe responses, authentication frames) as intermediaries to automate the setup process. These pre-defined message formats serve as mediators between terminals, enabling automatic communication and coordination without requiring complex custom protocols or additional hardware components.
Solution Approach 2:
The system merges multiple setup operations into a single automated workflow. Channel scanning, PIN generation, probe request transmission, authentication, and channel activation are combined into one seamless process triggered by user terminal selection, eliminating the need for separate manual operations for each step.
3Reliability
If separate operations are required for channel setup, then channel can be established, but other user functions cannot be performed simultaneously
Solution Approach 1:
The system maintains continuity of useful action by enabling parallel operations during channel setup. While the automated setup process executes in the background, users can continue performing other functions such as viewing terminal lists, selecting targets, or using other application features, ensuring that system productivity is not interrupted by the setup process.

AI summary
A system of Wi-Fi terminals and a channel operation method for the same are provided. The method includes selecting a user function of a sending terminal including a Wi-Fi module, determining whether the selected user function is a Wi-Fi related function, performing, when the selected user function is the Wi-Fi related function, by the sending terminal, a search for a terminal capable of handling the user function, selecting, by the sending terminal, a found terminal as a receiving terminal, automatically establishing, by the sending terminal, a Wi-Fi channel to the receiving terminal by automatically sending a Probe Request message containing a Personal Identification Number (PIN) code, sending, by the sending terminal, data generated by the user function to the receiving terminal through the Wi-Fi channel, and outputting, by the receiving terminal, the received data.
