Hourly statistical analysis of fade occurrence and duration

An approach to evaluating and specifying the availability and quality of performance of radiocommunication services is presented. The number and total duration of fade events, within independently processed clock hours, were observed by carrying out a two-year statistical analysis of Olympus 12.5 GHz beacon data. The hourly probability of given fade levels being exceeded was obtained by varying both the number of events and total excess time over the course of one hour. The possibility of modelling these parameters is explored, with satisfactory results
