Access Control Module Power Switching for AP Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication apparatuses operating in access point mode face challenges in reducing power consumption, particularly in managing the power levels of RF and baseband signal processing devices to extend battery life without compromising network access services.
Innovation Solution
The apparatus includes an access control module that switches the RF and baseband signal processing devices between different power levels based on indication signals, suspending transmission and reception during idle periods and rapidly turning them on to detect channel activity, ensuring network access without excessive power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the RF signal processing device and baseband signal processing device are kept at high power level to ensure continuous network access service, then the reliability of network service is improved, but the power consumption increases
Solution Approach 1:
The patent implements periodic switching between active and low-power states for the RF and baseband signal processing devices. The access control module monitors for communication activity during active periods and transitions devices to low-power levels during idle periods, creating a periodic on-off pattern that reduces overall power consumption while maintaining service availability.
Solution Approach 2:
The patent dynamically adjusts the power level of signal processing devices based on real-time communication conditions. The access control module continuously monitors for incoming communications and switches devices between first power level (active) and second power level (low-power) states, making the system adaptable to varying traffic conditions rather than operating at fixed power levels.
2Use of energy by moving object
If the RF signal processing device and baseband signal processing device are switched to low power level to save battery power, then the power consumption is reduced, but the response time to detect channel activity increases
Solution Approach 1:
The access control module maintains a listening state or monitoring mechanism that can quickly detect channel activity even when signal processing devices are in low-power mode. This preliminary monitoring capability allows the system to wake up or activate fully only when necessary, reducing the effective response time penalty of low-power operation.
Solution Approach 2:
The system employs periodic checks or listening intervals where the access control module briefly activates signal processing devices to detect channel activity, then returns them to low-power state. This periodic activation pattern balances power savings with timely detection of communication opportunities.

AI summary
A communications apparatus having an RF signal processing device, a baseband signal processing device and an access control module is provided. The RF signal processing device transmits and receives an RF signal and processes the RF signal in accordance with a predetermined protocol to generate a first signal. The baseband signal processing device is coupled to the RF signal processing device and processes the first signal. The access control module controls operations of the communications apparatus in at least a station mode and an AP mode. The access control module issues a first indication signal and a second indication signal under the AP mode so that the RF signal processing device and the baseband signal processing device are switched between a first power level and a second power level in the AP mode.
