802.11 Transceiver Reconfiguration for 10 MHz Multi-Mode Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication receivers are typically designed to operate in a single mode, requiring redesign to support other modes of operation, such as switching between 20 MHz and 10 MHz modes, which is inefficient and limits adaptability.
Innovation Solution
A communication receiver is configured to dynamically reconfigure its components, including the physical layer interface, radio receiver, and baseband processing modules, to support multiple stream and proprietary modes of operation, allowing it to adapt to different signal channel bandwidths and modes without the need for redesign.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the communication receiver is designed to operate in a single mode (e.g., 20 MHz mode), then the receiver can be optimized for that specific mode, but it requires redesign to support other modes of operation (e.g., 10 MHz mode), increasing device complexity and development time
Solution Approach 1:
The receiver is designed with universal components that can function across multiple modes of operation. The physical layer interface, radio receiver, and baseband processing modules are configured to handle different signal channel bandwidths (e.g., both 20 MHz and 10 MHz modes) without requiring hardware redesign, allowing one receiver design to serve multiple communication standards
Solution Approach 2:
The receiver incorporates dynamic reconfiguration capabilities where components can adapt their operating parameters based on the detected mode. The system dynamically adjusts its configuration to support different bandwidths and operational modes, transitioning from static single-mode design to dynamic multi-mode operation
2Adaptability or versatility
If the communication receiver is redesigned to support multiple modes of operation, then adaptability increases, but development time and cost increase
Solution Approach 1:
By designing universal receiver components that inherently support multiple modes, the development process creates a single platform that can handle various communication standards. This approach eliminates the need for separate development cycles for different modes, reducing overall development time while maintaining multi-mode capability
3Productivity
If the communication receiver operates in a fixed mode, then optimization for that mode is achieved, but flexibility to adapt to changing signal metrics is reduced
Solution Approach 1:
The receiver implements dynamic mode selection and reconfiguration based on real-time signal metric analysis. When signal conditions change, the system automatically adjusts its operating mode and bandwidth configuration to maintain optimal data rates, transitioning from fixed-mode operation to adaptive dynamic operation

AI summary
A method and apparatus is disclosed to dynamically reconfigure a communications receiver to support one or more single stream modes of operation, multiple stream modes of operation, and/or propriety modes of operation. The communications receiver is configured to support according to a first single stream mode of operation, multiple stream mode of operation, and/or proprietary mode of operation according to a known single stream communications standard, a known multiple stream communications standard and/or a proprietary communications standard. The communications receiver may receive a single stream communications signal and/or a multiple stream communications signal having a second single stream mode of operation, multiple stream mode of operation, and/or proprietary mode of operation according to a known single stream communications standard, a known multiple stream communications standard and/or a proprietary communications standard. The communications receiver may be dynamically re-configured to the second single stream mode of operation, multiple stream mode of operation, and/or proprietary mode of operation to process the single stream communications signal and/or a multiple stream communications signal.
