Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ambient power (AMP) devices face challenges in improving communication performance due to power consumption limitations and capabilities, particularly in scenarios where they rely on wireless radio frequency, light, solar, and thermal power sources.
Innovation Solution
Implementing a frequency division multiple access (FDMA) design for both uplink and downlink communications in AMP devices, allowing them to negotiate support for FDMA channels and dynamically configure channel parameters with the network side, enhancing communication performance by enabling simultaneous addressing of multiple devices and data transmission/reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If AMP devices use traditional single-channel communication, then power consumption is low, but communication performance and data capacity are limited
Solution Approach 1:
The patent applies frequency division multiple access (FDMA) to segment the available frequency spectrum into multiple channels, allowing AMP devices to communicate simultaneously on different frequencies. This segmentation enables parallel data transmission across multiple channels, thereby improving communication performance and data capacity while maintaining low power consumption characteristics of AMP devices.
2Quantity of substance
If AMP devices implement multi-channel FDMA communication, then data capacity increases, but device complexity increases
Solution Approach 1:
The patent implements a universal FDMA mechanism that can be applied across multiple communication channels with standardized negotiation protocols. The network device and AMP device use common negotiation procedures to determine channel allocation, making the system scalable and reducing the complexity burden on individual AMP devices while enabling high data capacity through multi-channel operation.
3Adaptability or versatility
If AMP devices negotiate FDMA support dynamically, then adaptability improves, but communication setup time increases
Solution Approach 1:
The patent implements preliminary channel negotiation where AMP devices and network devices exchange capability information and establish FDMA support parameters before actual data transmission begins. This preliminary action allows the system to pre-configure optimal channel allocations and negotiation outcomes, enabling rapid adaptation to different communication scenarios while minimizing the time required for subsequent data transmission.
