Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IoT gateway devices are limited to transmitting at specific power increments, leading to interference when multiple devices are proximate, and service providers face challenges in managing power levels due to manufacturer-specific command syntaxes.
Innovation Solution
Implementing mechanisms for gateway devices to adjust RF power levels using RF attenuators and standardized communication structures between network servers and gateway devices to ensure precise power transmission without interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If gateway devices transmit at fixed power increments, then device simplicity is maintained, but interference occurs when multiple devices are proximate
Solution Approach 1:
The patent applies dynamics by enabling the gateway device to dynamically adjust its RF power transmission level based on real-time environmental conditions and detected interference from other devices. Instead of fixed power increments, the system continuously monitors and adapts transmission power to optimize performance while minimizing interference.
Solution Approach 2:
The patent implements parameter changes by allowing the gateway device to vary its transmission power parameter beyond fixed increments. The system modifies the RF power level parameter dynamically based on detected interference conditions, enabling fine-grained control over transmission strength to eliminate harmful interference while maintaining device simplicity.
2Reliability
If manufacturer-specific command syntaxes are used, then device functionality is maintained, but service providers face challenges in managing power levels
Solution Approach 1:
The patent applies universality by implementing a standardized command syntax that can be used across different gateway devices from various manufacturers. This universal interface allows service providers to manage power levels uniformly without needing to learn multiple manufacturer-specific protocols, while the system translates these standardized commands into the appropriate device-specific instructions.
Solution Approach 2:
The patent uses an intermediary approach by introducing a standardized command layer that mediates between the service provider's control interface and the manufacturer-specific device implementations. This intermediary syntax translates high-level power management commands into device-specific instructions, simplifying service provider operations while maintaining compatibility with diverse hardware.
Data Source
AI summary
A gateway device receives a first message from a server device, the first message comprising a first power level indicator corresponding to a first desired output radio frequency (RF) power level for the gateway device, the gateway device being inoperable to transmit at the first desired output RF power level. In response to the first message, the gateway device sets an output RF power level of the gateway device to an output RF power level that is different from the first desired output RF power level. The gateway device sends, to an RF attenuator that is communicatively coupled to an RF output of the gateway device, an instruction to attenuate the output RF power level of the gateway device such that an attenuated output RF power level matches the first desired output RF power level.
