DataTAC is a wireless data network technology originally developed by Mobile Data International which was later acquired by Motorola , who jointly developed it with IBM and deployed in the United States as ARDIS (Advanced Radio Data Information Services). DataTAC was also marketed in the mid-1990s as MobileData by Telecom Australia, and is still used by Bell Mobility as a paging network in Canada.
