Wireless Frame Segmentation for Scheme Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication apparatuses experience reduced communication throughput and data loss when switching between wireless communication schemes with different maximum transmission frame sizes, as they cannot efficiently handle frames larger than the new scheme's maximum size.
Innovation Solution
A wireless communication apparatus and method that includes a scheme selector, transmission frame generator, and divider, which divides transmission frames into smaller segments if they exceed the maximum size of the selected scheme, ensuring seamless switching and retransmission across different wireless communication schemes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wireless communication scheme is switched adaptively to utilize a stable communication environment, then the communication reliability is improved, but data loss occurs during switching
Solution Approach 1:
The patent divides the transmission frame into multiple smaller frames when the frame size exceeds the maximum transmission frame size of the selected wireless communication scheme. This segmentation allows the data to be transmitted in manageable chunks that fit within the constraints of different communication schemes, preventing data loss during scheme switching while maintaining communication reliability.
2Productivity
If the transmission frame size is increased to improve throughput, then the communication efficiency is improved, but data loss occurs when switching to schemes with smaller maximum frame sizes
Solution Approach 1:
The patent dynamically adjusts the transmission frame size based on the selected wireless communication scheme. When a scheme with a smaller maximum frame size is selected, the system dynamically segments the original large frame into multiple smaller frames. This dynamic adaptation allows the system to maintain high throughput by using large frames when appropriate while preventing data loss when switching to schemes with smaller frame size constraints.
3Adaptability or versatility
If the wireless communication apparatus is designed to support multiple schemes with different maximum transmission frame sizes, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent implements a universal frame handling mechanism that can accommodate multiple wireless communication schemes with different maximum transmission frame sizes. The transmission frame divider and controller work together to universally handle frame segmentation and reassembly operations, allowing the same hardware and software components to support various communication schemes without requiring separate dedicated handling mechanisms for each scheme.
