Abstract: A remote analysis system for equipment condition monitoring and the like, using a data acquisition device operable at the remote site of monitored equipment, a wide area network for communication of data to an analysis server, and an empirical model for analyzing operational performance based on data from the device. An information processor such as a personal computer (PC) or an embedded processor application is coupled to the data acquisition device for collecting signals indicative of the monitored machine or process. A communications network, such as a wireless or telephony network, or a wide area network application such as an intranet or the Internet, facilitates communications to an analysis server for conveying the collected signals to an application service provider (ASP) for analysis of the remotely monitored site. A communications server may also be used for facilitating communications via a number of different communications networks.
