Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ambient power (AMP) devices face challenges in improving communication performance due to their power consumption limitations and capabilities, particularly when using wireless radio frequency, light, solar, and thermal power sources.
Innovation Solution
The AMP device negotiates with the network side to support uplink and/or downlink FDMA, enabling improved communication performance through FDMA design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If FDMA is implemented in AMP devices, then communication performance and data transmission capability are improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic FDMA configuration where the network device negotiates with the AMP device to determine the number of FDMA channels based on current communication needs. The first information exchanged during negotiation allows the system to adaptively allocate frequency resources, enabling the AMP device to use FDMA only when necessary for improving communication performance, thus balancing productivity improvement with power consumption management.
2Productivity
If multiple FDMA channels are allocated to AMP devices, then simultaneous addressing of multiple devices and data transmission are improved, but device complexity increases
Solution Approach 1:
The patent employs preliminary negotiation between the network device and AMP device to determine FDMA channel allocation before actual data transmission. The first information is exchanged in advance to establish the number of FDMA channels to be used, allowing the AMP device to prepare its communication stack accordingly. This preliminary configuration simplifies the device complexity by avoiding the need to support all possible FDMA configurations simultaneously, while still enabling high productivity when needed.
