A W-band measurement system for wireless channel modeling

We describe the details of a W-band scaled measurement system designed for wireless channel modeling. As the measurement wavelength in this system is about two orders of magnitude smaller than actual wavelength in commercial wireless systems, a typical dimension of the propagation environment will be in the same order of magnitude smaller than the actual environment. Hence propagation measurements can be done very efficiently under laboratory conditions using a small model of a city block. This system is intended for verifying the result of propagation prediction software. The system can also be used to investigate the accuracy of representing complex scattering objects such as buildings with simple canonical geometries.
