1. Radio wave simulation technology that can simply and automatically determine installation points for wireless devices
Fujitsu Laboratories has simplified the handling of radio wave simulations, which previously required huge amounts of time and effort, with the following two technologies, which can simply and automatically determine installation points for wireless devices, even without wireless device expertise.
1) 3D spatial digitizing technology:
Fujitsu Laboratories has developed technology to automatically create the 3D layout data necessary for radio wave simulations just by measuring with a laser scan from a few points around the site, and then automatically correcting distortions and smoothly merging measurement data from multiple scans. With this technology, the time required to create the layout data is shortened from around one week when creating it by hand to around two hours, including measurement time.
2) Moving body modeling technology:
In order to reflect the impact of people's movements numerically, it was previously necessary to run many simulations, changing the placement of people a bit each time. Now, by automatically measuring the number of people coming and going using technology developed by Fujitsu Laboratories that recognizes the flow of people from video(1), making patterns for different numbers of people, and using these in simulations, simulations that might have taken three days can now be done on an ordinary PC in less than fifteen minutes.

2. Radio wave interference visualization technology
Fujitsu Laboratories has developed technology that automatically recognizes and displays wireless communications actually being used at sites where IoT devices are installed, and visualizes the state of signal congestion for each channel and location, and for each communications standard. This makes it possible, even for non-experts, to determine appropriate installation locations for IoT devices, data transmission time spacing, and channel settings.
This technology recognizes wireless standards (such as Wi-Fi, Bluetooth and ZigBee) through a unique computation method of correlation coefficient between received signals and signal patterns prepared for each wireless standard. Previous technology would perform a product-sum operation with signal patterns prepared for each standard, after frequency correction of the received signal, but this technology uses the fact that, when the received signal differs from the prepared signal pattern, the results of multiplication of the signal before frequency correction have high randomness to achieve high recognition performance, successfully improving recognition sensitivity to twice that of previous methods.

Effects
With this newly developed technology, Fujitsu Laboratories has reduced the time required to install IoT devices at a site to one-third that of previous methods.
This means that, because the installation of wireless devices, which created issues for implementing and operating an IoT system, and radio wave congestion and interference countermeasures have become easier to do, when using an IoT system with the goal of achieving operational efficiencies or to create value, customers can greatly reduce the time needed before they start actual operations. In addition, even after starting operations, these technologies also make it possible to operate stably, without any major trouble causing operations to stop.
