Wireless Site Survey System Using Server-Driven Condition Maps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current site survey methods for wireless communication do not consider time slots, leading to inefficiencies and inaccuracies in determining unmeasured and insufficient areas for wireless information collection, as the conditions for site surveys vary by time slot.
Innovation Solution
A wireless information collecting method and system where user terminal devices periodically measure their position and transmit this information to a server, which creates and updates a condition map indicating the necessary wireless information measurement number at specific positions and times, allowing for targeted and efficient site surveys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a user terminal collects all wireless information during operation, then the quantity of wireless information is increased, but the accuracy of ascertainment of radio wave state deteriorates due to large error factors
Solution Approach 1:
The patent extracts only the necessary wireless information from the large amount of collected data by using a server to determine which measurements are actually needed for accurate site survey, thereby eliminating error-prone redundant measurements while maintaining data quality
Solution Approach 2:
The server receives wireless information from user terminals, determines whether additional information is needed, and provides feedback instructions to guide further measurements, creating a closed-loop system that optimizes measurement accuracy by adaptively selecting which data to collect
2Measurement precision
If a measurer manually checks position and determines measurement locations, then the ease of operation deteriorates, but the measurement precision can be maintained
Solution Approach 1:
The system enables automated position tracking and measurement instruction generation, where the server automatically determines measurement locations and requirements based on received data, eliminating the need for manual position checking and decision-making by the measurer
3Reliability
If site survey is repeated to account for environmental fluctuations, then the productivity decreases, but the reliability of wireless information is improved
Solution Approach 1:
The server pre-determines the necessary number and types of wireless information measurements needed before actual measurement begins, allowing the system to plan measurements efficiently and avoid redundant repeated surveys by anticipating what data will be sufficient for reliable results
4Productivity
If the server determines unmeasured areas and insufficient information requirements, then the device complexity increases, but the productivity of site survey is improved
Solution Approach 1:
The server performs multiple functions including receiving wireless information, determining unmeasured areas, calculating insufficient information requirements, and generating measurement instructions, consolidating these capabilities into a single multi-functional system that improves overall survey efficiency

AI summary
In a wireless information collecting method executed by at least one user terminal device that measures wireless information used in a site survey and a server device that stores the wireless information and performs the site survey, the user terminal device performs a step of periodically measuring a current position and transmitting positioning information indicating the current position to the server device, and a step of measuring the wireless information in accordance with a wireless information measurement number instructed by the server device and transmitting wireless information including a position and time to the server device. The server device performs a step of associating a position of the user terminal device and time with the wireless information and creating and updating a condition map indicating a wireless information measurement number at a position and time at which a site survey is performed, and a step of collating the current position of the user terminal and the time with the condition map and transmitting an instruction for the wireless information measurement number based on the current position of the user terminal device and the time to the user terminal device.
