| Abstract(in English) | As the Internet of things (IoT), in which various devices and systems are connected to networks, rapidly spreads, there is a growing need for technology to visualize radio environment of interference waves for as short a time as possible in order to deal with system failures caused by radio wave interference. In this research, we show an interpolation method for faster visualization of the radio wave environment. In the proposed interpolation method, in addition to the global distance attenuation characteristics, it is possible to reproduce the received power difference over non-line-of-sight and line-of-sight and the local power drop due to shielding by buildings. In the verification in an urban area, we confirmed that the RMS error of the received power due to the interpolation was suppressed to 6.8 dB, and the time required to visualize the radio wave environment could be decreased by about 80%. |
