Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If down-clocking is used to create new wireless LAN specifications, then transfer distance is improved, but adaptability is worsened
Solution Approach 1:
The patent makes the clock frequency dynamic by allowing wireless communication devices to change their operation clock frequency between a first clock frequency and a second clock frequency (which is a down-sampled version of the first). This enables the system to adapt transfer distance dynamically without creating new specifications, resolving the contradiction between fixed down-clocking approaches and dynamic adaptability.
Solution Approach 2:
The patent changes the clock frequency parameter to control transfer distance. By switching between different clock frequencies (first and second frequencies), the system can adjust transfer distance on demand. This parameter change approach provides dynamic adaptability while maintaining compatibility with existing wireless LAN specifications.
2Speed
If wireless LAN specifications are changed to achieve desired transfer speed, then transfer speed is improved, but device complexity is worsened
Solution Approach 1:
The patent makes a single wireless communication device capable of operating at multiple transfer speeds by utilizing both the first clock frequency and the second clock frequency. This multi-functionality allows the device to achieve different transfer speeds without requiring multiple specialized devices or complex specification management, thereby reducing device complexity.
3Length of stationary object
If wireless LAN specifications are changed to achieve desired transfer distance, then transfer distance is improved, but manufacturing precision is worsened
Solution Approach 1:
The patent performs preliminary action by pre-defining the relationship between the first clock frequency and the second clock frequency (where the second is a down-sampled version of the first). This preliminary setup allows the system to achieve different transfer distances without ad-hoc specification changes, maintaining manufacturing precision and standardization while enabling flexible distance adjustment.

AI summary
Provided is a wireless communication method in a wireless communication device that performs wireless communication in compliance with a prescribed wireless communication specification. A first clock frequency is configured as a clock frequency of an operation clock of the wireless communication device, and a first communication sequence is executed in which a second clock frequency is derived, between the wireless communication device itself and a different wireless communication device, using the first clock frequency. A second clock frequency that is derived in the first communication sequence is configured as the clock frequency of the operation clock of the wireless communication device, and a second communication sequence is executed in which data communication is performed, subsequently to the first communication sequence, between the wireless communication device itself and the different wireless communication device, using the second clock frequency.
