Multiband Multimode Selector for Dynamic Spectrum Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limited and non-contiguous frequency spectrum allocated to wireless network operators by government agencies, such as the FCC, is insufficient to meet the increasing demands for data services, leading to challenges in maintaining quality of service (QOS) metrics like high data rates and low latency.
Innovation Solution
A multiband, multimode user device equipped with a selector that dynamically chooses multiple channels, frequency bands, and modes based on demand and resource availability, allowing for the distribution of data flow requests across multiple frequency bands and modes, such as combining CDMA and LTE standards, to satisfy network demands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single frequency band or mode is used, then device complexity is reduced, but network capacity and data rates become insufficient to meet increasing demand
Solution Approach 1:
The patent implements dynamic selection of frequency bands and modes based on real-time network conditions and traffic demands. The system can adaptively switch between single-band and multi-band operation, adjusting the level of complexity according to current productivity requirements rather than operating at fixed complexity levels
Solution Approach 2:
The patent segments the network operation into multiple independent frequency bands and modes that can be selectively activated. Instead of using the entire spectrum continuously, the system divides available resources into discrete segments (bands 1, 2, 3... and modes A, B, C...) that can be independently managed and combined based on demand
2Productivity
If multiple frequency bands and modes are used simultaneously, then data rates and network capacity increase, but resource allocation complexity and management difficulty increase
Solution Approach 1:
The patent employs feedback mechanisms where the system continuously monitors network conditions, traffic patterns, and performance metrics across different bands and modes. Based on this feedback, the resource allocation controller dynamically adjusts which bands and modes are active, optimizing data rates while managing complexity through informed decision-making rather than exhaustive search
Solution Approach 2:
The patent changes operational parameters (frequency band selection, mode selection, power allocation) dynamically based on network conditions. Rather than maintaining fixed complex resource allocation schemes, the system adjusts parameters in response to changing demands, achieving high data rates when needed while reducing complexity during lighter traffic conditions
3Reliability
If the allocated frequency spectrum is used exclusively by one operator, then service quality is maintained, but spectrum utilization efficiency decreases when demand exceeds allocation
Solution Approach 1:
The patent enables the user device to operate across multiple frequency bands that may be allocated to different network operators or services. The device and network can dynamically share spectrum resources across operator boundaries, allowing the same physical spectrum to serve multiple functions and operators simultaneously, thereby improving overall utilization efficiency while maintaining service quality through coordinated multi-operator operation
