Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems operating in the 2.4 GHz frequency band face challenges with low data rates and extended range due to slower transmission times, leading to latency and low throughput, especially in outdoor IoT networks and smart home devices.
Innovation Solution
Implementing an extended long range (ELR) wireless packet design with duplication schemes, such as blockwise repetition and frequency domain duplications, and resource allocations like distributed resource units (dRUs) to enhance data rate and coverage range, while maintaining compatibility with existing systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If 2.4 GHz frequency band is used for long range wireless communication, then coverage range is improved, but data rate decreases
Solution Approach 1:
The data portion of the wireless packet is segmented into multiple duplications and transmitted across different resource units (RUs). This segmentation allows the system to utilize frequency diversity and improve reliability without sacrificing data rate, as multiple segments can be combined at the receiver side.
Solution Approach 2:
The patent introduces a new dimension of transmission by distributing packet duplications across multiple frequency-domain resource units instead of using a single continuous frequency band. This dimensional approach allows simultaneous achievement of extended range through frequency diversity and maintained data rate through parallel transmission paths.
2Length of stationary object
If transmission time is extended for long range communication, then coverage is improved, but latency increases
Solution Approach 1:
The patent employs periodic transmission of packet duplications across multiple resource units in a structured manner. This periodic action allows the receiver to accumulate information from multiple transmissions, improving range while the structured periodicity ensures predictable and controlled latency through systematic combining of duplications.
3Reliability
If packet duplication scheme is implemented for ELR mode, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent creates multiple copies (duplications) of the data portion and transmits them across different resource units. This copying approach improves reliability through redundancy and frequency diversity while keeping the complexity manageable by using standardized copying mechanisms that leverage existing wireless communication processing capabilities.
4Productivity
If multiple duplications of data portion are transmitted, then throughput is improved, but use of energy increases
Solution Approach 1:
The patent applies different transmission qualities to different portions of the packet. The data portion is duplicated and transmitted across multiple resource units with optimized power allocation, while the preamble portion uses standard transmission. This local quality differentiation improves throughput for the data-critical portion while minimizing overall energy consumption.
