Vistar's GlobalWave asset tracking and monitoring system began commercial operation through its subsidiary Vistar Datacom in Canada/U.S. in late 1999. By the end of 2001, operations will also be underway through Regional Operators in Australia, Europe, South Africa and the Middle East, with others to follow.

This system provides tracking, monitoring and control and short message services to a wide variety of fixed and mobile assets, including trailers, railcars, heavy equipment, ships, fixed tanks, pumping stations, meter reading, a variety of fixed and mobile security applications, among others.
User terminals for this system are characterized by exceptionally low power consumption and low latency, thereby providing near-real time monitor and control. The end user business or Value Added Reseller (VAR) very often accesses the GlobalWave system via Internet, which requires a GlobalWave Value-Added Application Server (GWVAS) to interface GlobalWave data with the back-office business operations of the company.
Initial development of a prototype GWVAS for the GlobalWave DGS System was undertaken in early 2000, but it became clear that the feature set was inadequate to serve specialized market segments (e.g. custom web pages for marine use), was difficult to in
