Wi-Fi Wake-Up Control for Low-Power Wearable Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices with integrated Wi-Fi modules experience excessive power consumption due to frequent wake-up events from receiving irrelevant data packets, leading to prolonged system activation.
Innovation Solution
A network connection method that disables the Wi-Fi module when the device is in a low power mode and detects frequent wake-up events or non-use scenarios, switching to alternative communication methods like Bluetooth or NFC when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the Wi-Fi module is kept enabled to maintain network connectivity, then communication reliability is improved, but power consumption increases due to frequent wake-up events
Solution Approach 1:
The Wi-Fi module's operational state is dynamically adjusted based on device usage patterns. The system transitions the module between enabled and disabled states according to whether the device is in low-power mode or active mode, optimizing the balance between connectivity reliability and power consumption.
Solution Approach 2:
The system changes the operational parameters of the Wi-Fi module by disabling it under specific conditions (low-power mode with frequent wake-up events) and enabling it when needed. This parameter change allows the system to reduce power consumption while maintaining connectivity when necessary.
2Use of energy by moving object
If the Wi-Fi module is disabled to reduce power consumption, then energy usage is reduced, but network connectivity is lost
Solution Approach 1:
The system introduces an intermediary mechanism (the conditional control logic) that manages the Wi-Fi module's state. This intermediary evaluates device state and wake-up event frequency to determine whether to enable or disable the module, allowing indirect control that balances power savings with connectivity needs.
Solution Approach 2:
The system performs preliminary assessment of device state and wake-up patterns before disabling the Wi-Fi module. By evaluating whether the device is in low-power mode and whether wake-up events exceed a threshold, the system proactively decides to disable the module, preventing unnecessary power consumption before it occurs.
3Speed
If the device wakes up frequently to process data packets, then network responsiveness is improved, but system activation time increases
Solution Approach 1:
The system extracts the Wi-Fi module from continuous operation and isolates it in a disabled state when not needed. By taking out the module from the active power chain during low-power mode, the system eliminates the time and energy associated with frequent wake-up cycles while maintaining the ability to re-enable connectivity when necessary.

AI summary
This application discloses a network connection method, a system, and a related apparatus. A first electronic device establishes a Wi-Fi connection to a network connection device by using a wireless fidelity Wi-Fi module. The Wi-Fi module is disabled when it is detected that a quantity of occurrences of wake-up events in a first time period is greater than a first quantity of times, and the first electronic device is in a low power mode. The wake-up event is an event that when the first electronic device receives a data packet through the Wi-Fi connection, an interrupt controller is triggered to wake up the first electronic device from a sleep state to a working state. In this way, power consumption caused by frequent wake-up in a low power mode can be avoided.
