Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems operating in the 2.4 GHz band face challenges with low data rates and limited range due to slower transmission times, leading to latency and low throughput, especially when compared to higher frequency bands.
Innovation Solution
Implementing an extended long range (ELR) wireless packet design that includes duplication schemes for data portions and resource allocations using distributed resource units (dRUs) to enhance coverage and data rate, leveraging techniques such as blockwise repetition, binary convolutional coding, and low-density parity check interleaving.

Engineering Contradiction Analysis
1Length of stationary object
If wireless communication operates in the 2.4 GHz band to extend coverage range, then transmission range and object penetration improve, but data rate and transmission speed decrease
Solution Approach 1:
The data portion of the wireless packet is segmented into multiple duplications (e.g., 4 duplications) that are transmitted separately. This segmentation allows the receiver to combine multiple copies of the same data, improving reliability and effective data rate through diversity combining while maintaining extended range operation in the 2.4 GHz band.
Solution Approach 2:
The system changes transmission parameters by introducing a duplication scheme where the data portion is repeated multiple times within a single packet structure. This parameter change (adding duplications) improves the effective data rate and reliability without changing the fundamental 2.4 GHz band operation, thus maintaining extended coverage range.
2Length of stationary object
If wireless communication operates in the 2.4 GHz band to extend coverage range, then transmission range improves, but transmission time increases causing latency
Solution Approach 1:
The data portion is prepared in advance with multiple duplications embedded in the packet structure before transmission. This preliminary action ensures that the receiver can immediately combine the duplications upon receipt, reducing processing delay and overall transmission time while maintaining extended range capability.
3Reliability
If data portion is duplicated multiple times to improve reliability and data rate, then decoding accuracy improves, but packet structure complexity increases
Solution Approach 1:
The data portion is copied multiple times (e.g., 4 duplications) and placed in a structured format within the packet. This copying approach improves decoding accuracy through diversity combining at the receiver while maintaining a relatively simple and standardized packet structure that is easy to parse and process.
