Wireless Station Installation Design Optimizing Cost and Performance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional station installation design methods for wireless networks cannot effectively combine multiple wireless systems to achieve efficient communication performance versus cost, as they only consider reception power and not the specific communication performance and cost differences between various wireless systems.
Innovation Solution
A computer-based station installation design method that calculates reception power for each terminal from multiple base stations, converts this power into transmission rates using system-specific conversion tables, and optimizes base station placement based on a cost-performance evaluation index to accommodate terminals efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional station installation design based on reception power is used, then the design process is simple, but communication performance and system cost cannot be considered
Solution Approach 1:
The invention changes the evaluation parameter from simple reception power to a comprehensive evaluation index that includes transmission rate and system cost. This allows the design to consider both communication performance (through transmission rate) and economic factors (through system cost) simultaneously, resolving the contradiction between design simplicity and performance consideration
2Reliability
If station installation design considers multiple wireless systems, then communication performance versus cost efficiency is improved, but design complexity increases
Solution Approach 1:
The invention introduces a comprehensive evaluation index that quantifies both communication performance (transmission rate) and system cost into a single metric. This allows multiple wireless systems to be evaluated and compared systematically, managing the complexity of multi-system design while achieving cost-performance optimization
Solution Approach 2:
The evaluation index serves multiple functions simultaneously: it evaluates communication performance, compares different wireless systems, and optimizes cost-efficiency. This multi-functional approach handles the complexity of multi-system design through a unified framework

AI summary
In a station installation design method executed by a computer used as a station installation design apparatus that performs station installation design for a wireless system including a plurality of base stations having different wireless systems between at least two base stations, the station installation design method includes a reception power calculation step of calculating reception power from the base station in each terminal to be an evaluation point for each of one or the plurality of base stations arranged in a temporary installation state in a target area, a transmission rate acquisition step of converting each reception power calculated in the reception power calculation step into a transmission rate by using a conversion table prepared for each wireless system, and an arrangement step of changing the base station selected from one or the plurality of base stations in the temporary installation state based on a station installation design evaluation index value in consideration of a cost of the base station to an installation state, and making the terminals which can be accommodated in the selected base station accommodated among the unaccommodated terminals, wherein the reception power calculation step, the transmission rate acquisition step, and the arrangement step are repeatedly executed.
