Abstract: We present path gain results at 3,500 MHz from a mobile channel measurement campaign that was carried out at the ITS Table Mountain Field Site. The purpose of this effort was to validate measurements obtained from a prototype sliding correlator channel sounder that is currently under development at ITS. The validation framework we developed consists of two parts: 1) a CW channel sounder to provide a highly accurate reference, and 2) a series of static paths and a mobile route over which to compare path gain results from the two systems. We obtained excellent agreement in measured path gains between the sliding correlator and the CW systems.
