When using millimeter and sub-terahertz waves in wireless communications, complex phenomena such as absorption, reflection, scattering, and delay of radio waves are significant. Therefore, a detailed evaluation of propagation paths is necessary.
This white paper explains the basic theory and measurement system of "Channel Sounding", a technology for estimating radio wave propagation paths.
