Wireless Capacity Calculation Method for Manufacturing Tools

Abstract

Recently, the demand for utilizing wireless communication such as Wi-Fi is growing in manufacturing sites because Internet of Things (IoT) and wireless robots are becoming important for improving productivity with factory automation. On the other hand, when too many wireless tools are introduced, communication performance is degraded due to mutual interferences, resulting in less productivity. Thus, for improving productivity, it is important to know how many wireless tools can be stably introduced. To accommodate this demand, we investigate the capacity of radio communication (denoted by wireless capacity) required for wireless tools in manufacturing sites. In this paper, we show a simple but practical calculation method and results obtained by using captured data in a factory.
