Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate dedicated cables are used for power and data transmission to the outdoor antenna module, then reliable power supply and data transmission are achieved, but installation complexity increases and cost increases
Solution Approach 1:
The patent combines power transmission and data transmission into a single RF cable infrastructure. The outdoor antenna module receives both power and I2C clock signals through the existing RF cable that connects to the access point, eliminating the need for separate dedicated power and data cables. This merging approach simplifies installation while maintaining reliable power supply and communication.
Solution Approach 2:
The RF cable is given multiple functions: it serves as both the power transmission medium and the data communication channel. The access point transmits both power signals and I2C clock signals through the same cable infrastructure, allowing the cable to perform multiple functions simultaneously, thereby reducing overall system complexity.
2Reliability
If separate dedicated cables are used for power and data transmission, then transmission reliability is improved, but water leakage risk increases
Solution Approach 1:
By merging power and data transmission into a single RF cable infrastructure, the patent reduces the number of cable connections and interfaces that could potentially leak water. Fewer separate cables mean fewer sealing points and connection areas where water infiltration could occur, while maintaining reliable transmission through the unified cable system.
3Device complexity
If traditional unidirectional signal transmission is used from AP to outdoor antenna module, then system simplicity is maintained, but bidirectional I2C clock signal transmission is not achieved
Solution Approach 1:
The patent implements dynamic bidirectional signal transmission capability on the existing RF cable infrastructure. The access point can dynamically transmit I2C clock signals both to and from the outdoor antenna module, allowing the system to adapt to different communication directions and requirements without requiring separate dedicated cables for each direction.
Solution Approach 2:
The RF cable infrastructure is designed to handle multiple signal types and transmission directions. It can carry power signals, I2C clock signals, and other data communications simultaneously in both directions, making the system more versatile and adaptable while maintaining relative simplicity through a unified infrastructure.

AI summary
Implementations of the present disclosure relate to a circuitry system for a wireless system. The circuitry system includes a first circuit located at the outdoor antenna module, and a second circuit and a third circuit located at the wireless access point. When any component on the outdoor antenna module triggers the clock stretch, the state of demodulated clock signal will change, and the first circuit can change the power consumption level of the outdoor antenna module according to the state change. The second circuit can sense changes in the power consumption level and can output a control signal corresponding to the power consumption level. The control signal can control the third circuit. The third circuit can associate the state of the initial clock signal with the clock stretch state of the plurality of components according to the control signal, thereby realizing bidirectional transmission of the clock signal.
