Abstract :
A scaled propagation measurement system (SPMS) is developed as an alternative to the time consuming and expensive measurements for wireless channel characterization. This system allows accurate measurements of well-defined channels in a laboratory environment. Confining the desired range of frequency to systems operating at UHF to L-Band (0.5-2 GHz), dimensions of the scatterers and terrain features can be reduced by a factor of 50-200 for the SPMS that operates at around 100 GHz. The system includes a probe positioner, scaled model of city, miniaturized millimeter wave transceivers probes, and a network analyzer. SPMS is capable of measuring path loss as well as power delay profile (PDP) for any desired environment. It can be used to verify available channel models or collect data for developing new models. The system has a dynamic range around 85 dB and a nominal spurious level of -40 dBc.
