Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems are limited by their ability to transmit data within a single center frequency, restricting bandwidth and output power, which affects transmission range, reliability, and throughput.
Innovation Solution
The method involves transmitting information across multiple frequency ranges using the same wireless transmitter, with the power amplifier capable of handling the frequency differences between these ranges, allowing for concurrent transmission of multiple signals with different center frequencies, thereby increasing data capacity and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a transmitter transmits a signal at a particular center frequency, then the transmitter can operate within regulatory power limits, but the transmission range, reliability, and effective throughput are limited
Solution Approach 1:
The patent applies frequency diversity by transmitting signals across multiple frequency ranges (e.g., sub-6 GHz and millimeter wave bands) rather than a single center frequency. This dimensional expansion in the frequency domain allows the system to overcome limitations of individual frequency bands, achieving both compliance with power limits and improved transmission reliability through selective frequency usage.
Solution Approach 2:
The patent segments the transmission spectrum into multiple frequency ranges, each with its own power amplifier and control mechanisms. This segmentation allows independent optimization of each frequency band, enabling the system to transmit at maximum allowable power in each band while maintaining overall reliability through diversity.
2Device complexity
If a transmitter uses a single center frequency, then the device complexity is reduced, but the data transmission capacity is limited by bandwidth constraints
Solution Approach 1:
The patent expands the frequency domain dimension by utilizing multiple frequency ranges simultaneously, including both sub-6 GHz and millimeter wave bands. This dimensional expansion dramatically increases available bandwidth and data transmission capacity while managing complexity through shared baseband processing and coordinated resource allocation.
Solution Approach 2:
The patent implements a universal baseband processor that can handle multiple frequency ranges and modulation schemes. This multi-functional baseband unit reduces overall device complexity by avoiding separate dedicated processors for each frequency band, while still enabling high-capacity transmissions across multiple bands.
3Productivity
If a transmitter maximizes bandwidth around the center frequency, then the information capacity increases, but the transmitter is still limited to one center frequency by the local oscillator
Solution Approach 1:
The patent segments the frequency spectrum into multiple independent frequency ranges, each with its own local oscillator and power amplifier. This segmentation allows the system to maximize bandwidth utilization in each frequency band while maintaining the ability to independently tune and adapt each band's center frequency based on channel conditions and regulatory requirements.
Solution Approach 2:
The patent adds frequency flexibility by operating across multiple frequency dimensions (sub-6 GHz and millimeter wave bands) rather than being constrained to a single center frequency. This multi-dimensional frequency operation enables both high information capacity through bandwidth maximization in each band and adaptability through selective frequency band usage.
