Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks using multiple frequency bands, existing fixed time sharing protocols lead to inefficient use of transmission slots when one band has excessive data while another has minimal data, resulting in non-utilized portions and potential channel contention.
Innovation Solution
A dynamic wireless access manager module monitors usage and adjusts time slot ratios based on application priority and historical statistics, dynamically reallocating slots and migrating messages to orthogonal channels to minimize unused time slots and contention.

Engineering Contradiction Analysis
1Productivity
If a fixed time sharing protocol is utilized for sharing the transmission medium between two frequency bands, then each band is assigned a fixed time slot (e.g., 50-50 duty cycle), but this results in inefficient use of transmission slots when one band has excessive data while another has minimal data
Solution Approach 1:
The patent implements dynamic time slot allocation that adjusts the duty cycle ratio between frequency bands based on real-time data traffic conditions. Instead of a fixed 50-50 allocation, the system continuously monitors data volumes on each band and dynamically reassigns time slots to match actual usage patterns, ensuring high transmission efficiency under varying load conditions
Solution Approach 2:
The system changes the time slot allocation parameters (duty cycle ratios) based on traffic conditions. When one band has excessive data and another has minimal data, the parameters are adjusted to allocate more time slots to the congested band, optimizing overall transmission productivity
2Productivity
If a fixed time sharing protocol is utilized, then the transmission medium is shared between two frequency bands, but non-used portions of time slots result in wasted transmission opportunities
Solution Approach 1:
The system automatically monitors its own transmission medium usage and self-adjusts the time slot allocation without external intervention. The wireless access manager continuously tracks data traffic on each frequency band and autonomously reallocates time slots to eliminate unused portions, ensuring maximum utilization of available transmission capacity
3Ease of operation
If messages are transmitted on the same channel, then communication is simplified, but contention occurs when multiple devices attempt to use the same channel simultaneously
Solution Approach 1:
The patent segments the transmission medium by introducing orthogonal channels within frequency bands. When contention is detected on a channel, messages are migrated to orthogonal channels that do not interfere with each other, maintaining reliable communication while preserving the simplicity of channel-based transmission through structured channel organization
