Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless devices operate in specific frequency bands with limited transmit power, leading to inefficient use of bandwidth due to separate bands for different network types, resulting in underutilization of some bands and increased power consumption.
Innovation Solution
Implementing a radio access provider that allows wireless communication devices to select channels from multiple frequency bands, enabling the overlay of networks like GSM and LTE within a single band, thereby optimizing bandwidth usage and reducing the need for additional transceivers and antennas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate frequency bands are allocated for different network types (GSM, LTE, etc.), then each network type can operate independently with dedicated resources, but bandwidth utilization becomes inefficient and some bands remain underutilized
Solution Approach 1:
The patent merges multiple network types (GSM, LTE, etc.) into a single frequency band by implementing an overlay architecture where different network protocols share the same spectral resources. This allows simultaneous operation of multiple network types in the same band, improving bandwidth utilization while maintaining network type independence through protocol-layer separation.
Solution Approach 2:
The patent creates a universal frequency band infrastructure that can serve multiple network types simultaneously. By designing the system to handle different protocols (GSM, LTE, etc.) within a single band, the infrastructure gains multi-functionality, allowing the same spectral resources to be dynamically allocated to different network types based on demand.
2Reliability
If multiple separate transceivers and antennas are deployed for different network types, then each network type has dedicated hardware resources, but device complexity and power consumption increase
Solution Approach 1:
The patent implements a universal transceiver and antenna system that can operate across multiple network types within a single frequency band. This multi-functional hardware design eliminates the need for separate dedicated transceivers and antennas for each network type, reducing device complexity while maintaining reliable service across different protocols through software-defined radio capabilities.
3Reliability
If multiple separate transceivers and antennas are used for different network types, then each network type has dedicated hardware, but power consumption increases and battery life decreases
Solution Approach 1:
The patent employs a universal transceiver and antenna system that serves multiple network types within a single frequency band. This consolidation reduces the total number of active hardware components, thereby lowering power consumption and extending battery life while maintaining reliable network service through the ability to dynamically switch between different protocols using the same hardware resources.
4Reliability
If licensed bands are allocated exclusively to specific operators for defined terms, then service providers have guaranteed spectrum access, but spectrum flexibility and reuse are reduced
Solution Approach 1:
The patent segments the frequency band into multiple operational layers or virtual channels that can be dynamically allocated to different network types and operators. This segmentation allows licensed operators to maintain guaranteed access to specific segments while enabling flexible reuse of other segments for different purposes, balancing spectrum access reliability with adaptability.
Solution Approach 2:
The patent implements dynamic spectrum allocation mechanisms within the overlay band structure, allowing spectrum resources to be flexibly assigned and reassigned based on real-time demand while maintaining guaranteed access rights for licensed operators. This dynamic approach enables both reliability for licensed users and flexibility for overall spectrum utilization.

AI summary
In some implementations, a radio access provider, e.g., of a wireless telecommunications network, can receive, in a first frequency sub-band, control information of a first network. The provider can transmit, in a second sub-band, control information of a second network. The provider can transmit media information of the first network via first and second first-network channels in a third sub-band and transmit media information of the second network via a second-network channel arranged in frequency between the first and second first-network channels. In some implementations, the provider can select a first channel of the first network for first media; select a second channel of the second network for second media; select additional channels of the first network different in frequency from the second channel; and operate a first transceiver to wirelessly transmit the first media via the first channel and the additional channels.
