Wireless Preamble Signaling for AMP and Legacy Device Coexistence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The coexistence of ambient power (AMP) devices and legacy devices in communication systems is challenging due to their differing capabilities, necessitating a method to ensure compatibility.
Innovation Solution
A method involving the transmission of a preamble signal followed by a target signal, where the preamble signal indicates that the target receiving device is an AMP device, allowing legacy devices to identify and accommodate AMP devices in the communication system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If AMP devices are deployed in communication systems, then device complexity and power consumption are reduced, but compatibility with legacy devices deteriorates
Solution Approach 1:
The patent introduces a preamble signal as an intermediary element that mediates between AMP devices and legacy devices. The preamble signal contains indication information that allows legacy devices to identify and accommodate AMP devices, enabling coexistence without requiring legacy devices to be complex or AMP devices to have high power consumption
2Adaptability or versatility
If capability differences between AMP devices and legacy devices are addressed, then compatibility is improved, but system complexity increases
Solution Approach 1:
The patent segments the communication signal into two parts: a preamble signal containing indication information about device type, and a subsequent data signal. This segmentation allows legacy devices to quickly identify AMP devices through the preamble without needing to process complex capability negotiation protocols, thus improving coexistence while maintaining low system complexity
