Solution Overview
Problem
Current technologies lack a practical and cost-effective means to identify and protect interference-sensitive devices from nearby cellular transmissions, particularly in scenarios involving legacy devices like pacemakers and consumer electronics, which limits spectrum utilization and access.
Innovation Solution
A mobile initiator device uses Near-Field Communication (NFC) to generate an RF field, activate passive NFC components in interference-sensitive devices, and receive information about their interference sensitivity, allowing adjustments to operational aspects such as transmit power and frequency to accommodate these devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If shared spectrum use is implemented to support cellular growth, then spectrum utilization efficiency is improved, but interference-sensitive devices cannot be identified and protected
Solution Approach 1:
The mobile device performs NFC detection and identifies interference-sensitive devices before cellular transmission begins. By detecting the presence of sensitive devices in advance and obtaining their sensitivity information, the system can proactively adjust transmission parameters to avoid interference, thus enabling both shared spectrum use and protection of sensitive devices
Solution Approach 2:
Near-Field Communication (NFC) technology serves as an intermediary mechanism between mobile devices and interference-sensitive devices. The NFC component enables the mobile device to query and obtain sensitivity information from sensitive devices, facilitating coordinated spectrum sharing while protecting vulnerable devices through information exchange
2Difficulty of detecting and measuring
If NFC is used to detect interference-sensitive devices, then device identification capability is improved, but energy consumption increases
Solution Approach 1:
The NFC component is activated periodically or event-driven rather than continuously. The mobile device performs NFC detection at specific intervals or when entering potential interference zones, reducing energy consumption while maintaining effective detection capability when needed
Solution Approach 2:
The interference-sensitive device uses its own NFC component to provide sensitivity information autonomously when queried. This self-service approach eliminates the need for complex external detection systems, reducing overall system energy consumption while improving detection accuracy
