Wi-Fi Aware Standby Switching With BLE NAN for Lower Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses consume excessive power during standby mode due to enabling Wi-Fi Aware coupling, necessitating a technique to reduce power consumption.
Innovation Solution
Implementing a controller that switches between Wi-Fi Aware and Bluetooth Low Energy Triggers Neighbor Awareness Networking (NAN) functions based on power consumption states, enabling the Wi-Fi Aware function only when requested and using NAN for reduced power consumption when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the Wi-Fi Aware function is enabled during standby for coupling, then coupling capability is maintained, but power consumption increases
Solution Approach 1:
The patent applies dynamics by making the Wi-Fi Aware function state changeable - it can be enabled or disabled based on operational needs. The controller dynamically switches the Wi-Fi Aware function on when coupling is required and off when not needed, transforming a static always-on configuration into a dynamic on-demand configuration that adapts to operational requirements.
Solution Approach 2:
The patent applies preliminary action by enabling the Wi-Fi Aware function in advance before coupling operations are needed. The controller proactively activates the Wi-Fi Aware function when coupling capability is anticipated or required, ensuring the system is ready for coupling operations before they actually commence, rather than waiting until the last moment.
2Adaptability or versatility
If the Wi-Fi Aware function is kept enabled for service discovery, then discovery capability is improved, but power is consumed during standby
Solution Approach 1:
The patent applies periodic action by enabling the Wi-Fi Aware function only during specific periods when service discovery is needed, rather than continuously. The controller periodically activates the Wi-Fi Aware function to perform service discovery operations, then deactivates it during standby periods, creating an on-demand operational pattern that balances discovery capability with power conservation.
Solution Approach 2:
The patent applies preliminary action by enabling the Wi-Fi Aware function in advance of actual service discovery needs. The controller proactively activates the function when discovery operations are anticipated, ensuring the system is prepared for discovery before it actually begins, then deactivates it afterward to conserve power during non-discovery periods.

AI summary
A first electronic apparatus includes a controller and a first communication section that executes Wi-Fi Aware communication when Wi-Fi Aware coupling by a Wi-Fi Aware function is established between the first electronic apparatus and a second electronic apparatus. When the first electronic apparatus is in a first state related to power consumption, the controller stands by for coupling in a state where the Wi-Fi Aware function is enabled. When the first electronic apparatus is in a second state predetermined as a state where power consumption is to be reduced more than in the first state, the controller stands by for coupling in a state where a Bluetooth Low Energy Triggers NAN function is enabled. When the first electronic apparatus acquires a request to activate the Wi-Fi Aware function, the controller stands by for coupling in a state where the Wi-Fi Aware function is enabled.
