Performing channel sounding experiments is often considered a first step towards statistical channel modeling. The data obtained for a particular wireless channel environment is then analyzed and the channel is modeled by comparing it to known statistical models. Hence the authenticity of the experimental data is a most critical part in the process of channel modeling. We use channel sounding equipment called Sounder for statistical channel modeling. For synchronizing the transmitter and receiver local oscillators, the sounder manufacturer, Berkeley Varitronics Systems Inc., recommends calibrating the sounder, called “training”. But, there is an uncertainty about the time for which the sounder should be trained before taking measurements for a particular duration of time. After training, the allowed measurement time is estimated from parameters like current count and last count obtained during training, but it is not absolute. How the measurement data varies when the sounder is operated in measurement mode beyond the estimated measurement time is unknown. For this reason, the validity of data obtained during some field measurements is highly uncertain. This thesis work tries to understand the behavior of sounder when operated in measurement mode up to six times the allowed measurement time and succeeds at it. The conclusions drawn from this thesis work are very useful during field measurements to understand the measurement data logged for longer measurement times when the allowed measurement time is very less. This thesis work will also serve as a guide to the operation and understanding of our sounder for future students.
