Current wireless devices struggle to efficiently switch between WLAN and WPAN communication protocols, leading to suboptimal performance and power consumption due to the limitations of existing standards in managing protocol transitions and idle durations.
Innovation Solution
A wireless device that operates according to IEEE 802.15.4 standards during active durations and IEEE 802.11 standards during idle durations, utilizing a concurrent mode controller to multiplex operations and switch between protocols, allowing for efficient data transfer and power management by leveraging idle periods for power savings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a wireless device operates according to WLAN standards during active durations, then data transfer rates are improved, but power consumption increases
Solution Approach 1:
The wireless device alternates between WLAN operation during active durations and WPAN operation during idle durations, creating a periodic action pattern that optimizes both data transfer rates and power consumption by switching protocols based on operational requirements
Solution Approach 2:
The device dynamically switches between two communication protocols (WLAN and WPAN) based on whether it is in an active or idle duration, allowing it to adapt its operational mode to current network conditions and power requirements
2Adaptability or versatility
If a wireless device switches between WLAN and WPAN protocols, then communication versatility is improved, but device complexity increases
Solution Approach 1:
The concurrent mode controller uses periodic action by switching between WLAN and WPAN protocols based on predefined active and idle durations, providing communication versatility while managing complexity through structured protocol transitions
Solution Approach 2:
The concurrent mode controller acts as an intermediary that manages the switching between WLAN and WPAN protocols, handling the complexity of protocol transitions and allowing the wireless device to support multiple communication standards without requiring complex simultaneous multi-protocol operation
3Use of energy by moving object
If a wireless device utilizes idle durations for power-saving states, then power consumption is reduced, but data transfer capability deteriorates
Solution Approach 1:
The device employs periodic action by alternating between WLAN operation during active durations for data transfer and WPAN operation during idle durations for power saving, ensuring that data transfer capability is maintained when needed while reducing power consumption during idle periods
Solution Approach 2:
The device changes operational parameters by switching between two different communication protocols with different power and performance characteristics, utilizing WLAN for high-performance data transfer during active durations and WPAN for low-power operation during idle durations
