WLAN Adapter Automatic Setup via SCSI Optical Disk Emulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing WLAN adapter setups require cumbersome CD-ROM based software installation and can experience communication disruptions due to security software interference, leading to unstable connections when used with devices like LCD projectors.
Innovation Solution
A WLAN adapter configured as a USB dongle with a USB interface, programs for setting and executing communication, an optical disk drive identifier, a SCSI command interpreter, and a data converter, allowing automatic program execution and secure data transmission by recognizing the adapter as an optical disk drive, thus bypassing security software interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the WLAN adapter is recognized as a keyboard or memory device to enable automatic software loading, then the ease of operation is improved, but the reliability deteriorates due to security software interference and unintended automatic switching
Solution Approach 1:
The patent introduces an optical disk drive as an intermediary device type between the WLAN adapter and the host computer. By masquerading as an optical disk drive, the adapter can load installation programs automatically while avoiding detection and blocking by security software that monitors keyboard and memory device communications. This intermediary identity enables reliable data transmission without triggering security interventions.
2Ease of operation
If the adapter switches between memory device and WLAN adapter functions, then the ease of operation is improved, but the device complexity increases due to switching mechanisms
Solution Approach 1:
Instead of switching the adapter's function between memory device and WLAN adapter, the patent inverts the approach by maintaining a fixed WLAN adapter function while switching the perceived device type presented to the host computer. The adapter consistently operates as a WLAN adapter internally but presents different device identities (optical disk drive, keyboard, memory device) to the host computer depending on the installation phase, thereby eliminating internal switching complexity.
3Reliability
If security software monitors data transmitted to the WLAN adapter, then the reliability is improved for security purposes, but the ease of operation deteriorates due to communication blocking
Solution Approach 1:
The optical disk drive serves as a secure intermediary that bypasses security software monitoring. Installation programs and communication data are transmitted through the optical disk drive interface, which security software does not monitor or block. This intermediary channel enables continuous, uninterrupted communication while maintaining security software's protective function over actual WLAN data transmissions.
Data Source
AI summary
A wireless local area network (WLAN) device includes a WLAN adapter having a USB terminal connected to a USB terminal of a PC (personal computer). The WLAN adapter is loaded with a program for setting a WLAN and executing a communication, and a connection of the adapter to the PC prompts the PC to recognize the adapter as a CD-ROM drive, and prompts the program for setting a WLAN and executing a communication to run automatically. The PC loads data of SCSI standard into the WLAN adapter by using a vender defined command of SCSI standard by way of the program for setting a WLAN and executing a communication. The WLAN adapter converts the data of SCSI standard into data for setting a WLAN or data of TCP/IP (Transmission Control Protocol/Internet Protocol), and sets the WLAN and executes the communication.
