Abstract
A method for predicting a fault in a wireless communication path between at least one transmitter and a receiver. The method comprises detecting an initial value of a characteristic of a reception signal or an initial value of a characteristic of a wireless communication path, calculating a running average of the same characteristic for preset period of time, comparing the initial value with the calculated running average; and displaying an indication based upon an analysis of the comparing. The indication is transmitted to a remote site for response. The characteristic can be signal strength, noise and a S/N ratio.
