Problem
Long-range wireless communication technologies in IoT devices face issues with latency, data consumption, and cost, limiting their capabilities and data transmission/reception.
Innovation Solution
An electronic device with a transceiver that switches between long-range and short-range modes based on the power saving mode of the long-range communication technology, using a detection module and switching unit to optimize communication efficiency by switching to short-range mode during periods of inactivity or high power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If long-range wireless communication technology is used for IoT devices, then communication range is extended, but latency increases and power consumption increases
Solution Approach 1:
The transceiver dynamically switches between long-range and short-range communication modes based on real-time conditions. The system monitors power saving mode indicators from long-range networks and transitions to short-range mode when appropriate, optimizing both range and latency performance adaptively rather than using a fixed communication mode
Solution Approach 2:
The communication system is segmented into two distinct modes: long-range mode for extended coverage and short-range mode for low-latency communication. The transceiver can selectively activate either segment based on operational requirements, allowing the system to divide the communication function into specialized sub-functions that address different performance needs
2Length of stationary object
If long-range wireless communication technology is used for IoT devices, then communication range is extended, but power consumption increases
Solution Approach 1:
The system dynamically adjusts its communication mode based on power saving mode indicators received from the long-range network. When the long-range network enters a power saving mode, the transceiver transitions to short-range mode, thereby reducing power consumption while maintaining communication capability through adaptive mode switching
Solution Approach 2:
The transceiver changes its operational parameters by switching between different communication technologies based on the power saving mode status. This parameter change allows the system to optimize power consumption by selecting the appropriate communication mode (long-range or short-range) according to real-time network conditions
3Adaptability or versatility
If long-range wireless communication technology is used for IoT devices, then centralized server communication is enabled, but data consumption increases
Solution Approach 1:
The data transmission function is segmented into long-range transmission for essential server communications and short-range transmission for local data exchange. This segmentation allows the system to minimize long-range data usage while maintaining server connectivity, thereby reducing overall data consumption on the long-range network
