Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio base stations with separate WLAN and ESL radio modules require significant hardware adaptations to prevent interference, leading to high costs and inefficient radio activity coordination.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate WLAN and ESL radio modules are used with a control line for coordination, then radio activity interference is prevented, but hardware cost and complexity increase significantly
Solution Approach 1:
The patent replaces the mechanical/control line-based coordination system with a software-based solution. The base station controller uses software algorithms to predictively determine ESL radio module activity based on WLAN traffic patterns, eliminating the need for physical control lines and hardware modifications while achieving reliable interference prevention
Solution Approach 2:
The patent introduces a software intermediary (prediction algorithm) that mediates between WLAN and ESL radio modules. This intermediary analyzes WLAN traffic patterns and predicts ESL activity requirements, coordinating both modules through software logic rather than direct hardware control lines
2Reliability
If radio activities are coordinated only for current time period, then immediate interference is avoided, but future interference cannot be predicted and prevented
Solution Approach 1:
The patent implements preliminary action by using the prediction algorithm to anticipate future ESL radio module activity based on analyzed WLAN traffic patterns. The system proactively prepares coordination decisions for future time periods before interference actually occurs, rather than reacting only to current conditions
Solution Approach 2:
The patent employs feedback mechanisms where the prediction algorithm continuously monitors WLAN traffic patterns and adjusts its predictions of ESL activity requirements. This feedback loop enables the system to learn from past patterns and improve future interference prevention while optimizing radio resource allocation
3Productivity
If WLAN radio module operates with high priority, then WLAN communication performance is maintained, but ESL radio module communication is disrupted
Solution Approach 1:
The patent implements dynamic priority adjustment where the base station controller modifies radio module scheduling in real-time based on predicted activity requirements. The system dynamically shifts priority between WLAN and ESL modules according to the prediction algorithm's assessment of future communication needs, rather than maintaining static priority levels
