Autonomous Channel Selection for Wireless Data Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless data communication networks, especially those operating at frequencies like 2.4 GHz, interference from sources such as microwave ovens and Bluetooth devices can hinder data transmission, and existing solutions like DSSS modulation may not fully address the issue of channel availability due to limited capacity, leading to potential data loss and connectivity failures.
Innovation Solution
The implementation of a data communication network with transmitter and receiver units that include channel selection units capable of autonomously selecting and switching between data channels to minimize interference, allowing for continuous operation even when one channel becomes unsuitable, thereby reducing the risk of data loss and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If DSSS modulation technique is used to reduce interference effect, then data transmission reliability is improved, but channel capacity is still limited and not all devices can use the channel simultaneously
Solution Approach 1:
The patent divides the single data channel into multiple sub-channels or time slots, allowing multiple devices to access the communication medium simultaneously without interfering with each other. This segmentation resolves the contradiction by maintaining reliable data transmission through dedicated channels for each device while enabling multiple devices to share the overall channel capacity.
Solution Approach 2:
The patent implements dynamic channel allocation where the system can switch between different channels or time slots based on real-time conditions. This allows the system to adapt to varying levels of interference and device requirements, ensuring reliable transmission while maximizing channel accessibility for multiple devices.
2Reliability
If channel switching capability is implemented to avoid interference, then data transmission reliability is improved, but device complexity increases
Solution Approach 1:
The patent implements self-service channel selection where devices automatically detect interference levels and switch channels without requiring complex centralized control. Each device monitors its own transmission quality and autonomously selects optimal channels, reducing the need for complex inter-device coordination while maintaining high reliability.
Solution Approach 2:
The patent employs feedback mechanisms where transmission success or failure is communicated back to the transmitting device, which then adjusts channel selection accordingly. This simple feedback loop enables reliable data transmission through adaptive channel switching without requiring complex predictive algorithms or centralized management.
Data Source
AI summary
A data communication network. The network includes a transmitter unit for transmitting data and a receiver unit for receiving data from the transmitter unit. The network has two or more data channels via which data may be transmitted by the transmitter unit to the receiver unit. The receiver unit includes a receiver channel selection unit for selecting a reception channel from the at least two data channels. The receiver channel selection unit operates independent from a selection of a transmission channel by a transmission channel selection unit in the transmitter unit. The transmission channel selection unit is arranged to select a transmission channel from the at least two data channels to transmit data to the receiver unit.
