Wireless Congestion Measurement Excluding Permanent Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing congestion level measurement methods using wireless signals from mobile wireless terminals are inaccurate in venues with installed wireless terminals, leading to difficulties in accurately assessing congestion levels.
Innovation Solution
A congestion level measurement device and method that calculates the number of mobile wireless terminals carried by guests and distinguishes them from permanent wireless terminals in a venue, using a combination of wireless sensors and processing circuitry to determine the guest count and congestion level, thereby isolating the impact of installed terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If wireless signals from all wireless terminals are counted to measure congestion level, then the measurement covers all wireless devices in the venue, but the congestion level cannot be measured accurately when permanent wireless terminals are installed in the venue
Solution Approach 1:
The patent segments wireless terminals into two distinct categories: mobile wireless terminals (carried by guests) and permanent wireless terminals (installed in the venue). By separating these types and counting only mobile terminals, the system achieves accurate congestion measurement even in venues with permanent wireless infrastructure.
Solution Approach 2:
The patent extracts and excludes permanent wireless terminal data from the overall wireless terminal count. By identifying and removing signals from permanently installed terminals, the system isolates only the mobile terminal signals that represent actual guest presence, thereby resolving the measurement accuracy issue.
2Device complexity
If the number of all wireless terminals is used to represent guest count, then the calculation is simple, but the congestion level measurement becomes inaccurate in venues with installed terminals
Solution Approach 1:
The patent divides the wireless terminal population into mobile and permanent segments, allowing the system to maintain simple counting methodology while improving accuracy by selectively counting only mobile terminals that represent actual guests.
Solution Approach 2:
The patent introduces an intermediary classification mechanism that distinguishes between mobile and permanent terminals. This intermediary step enables accurate guest count estimation without significantly complicating the overall measurement process.
