Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques for converting wired communication to wireless communication lack the ability to perform communication management, such as quality measurement and rate adjustment, in the wireless transmission section.
Innovation Solution
A wireless transmitter that inserts a wireless control signal in the intervals between frames of a wired signal, using a received bit pattern and generating a wireless signal for transmission, enabling communication management in the wireless transmission section.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a wired signal is converted to a wireless bit pattern for transmission, then wireless transmission can be achieved, but communication management such as quality measurement and rate adjustment cannot be performed in the wireless transmission section
Solution Approach 1:
The transmission signal is segmented into data portions and interval portions. Control signals for wireless communication management are inserted into the interval portions between frames, separating data transmission from control functions while enabling both capabilities simultaneously
Solution Approach 2:
A control signal is introduced as an intermediary element that carries wireless communication management information. This control signal is inserted in the interval between wired signal frames, enabling quality measurement and rate adjustment without interfering with the primary data transmission function
2Ease of operation
If control signals are inserted in intervals between wired signal frames, then communication management is enabled, but signal complexity increases
Solution Approach 1:
Control signals are inserted periodically at fixed intervals between wired signal frames rather than continuously. This periodic insertion pattern simplifies the signal structure compared to continuous control signal embedding, making the system easier to implement and manage

AI summary
A wireless transmitter includes: wired reception units that each receive a wired signal transmitted by wire and including a plurality of frames; a wireless control signal applying unit that inserts a wireless control signal, which is a control signal for wireless communication management, in an interval in which no information transmission is performed between the frames of the wired signal received; and a wireless signal generation unit that generates a wireless signal to be wirelessly transmitted by using a received bit pattern of the wired signal and the wireless control signal.
