This division of AT T began life as McCaw Cellular Communications, Inc. AT T acquired McCaw in 1994 after McCaw had established a substantial market position for cellular services around the world. The business changed its name to AT T Wireless Services in 1995. By then, it had a number-one position in North America in additional to its global presence. Wireless Services purchased or manufactured and then distributed wireless technology hardware for its customers. It had also established a "core competence" in manufacturing and a reputation for performance excellence in the marketplace.

With a business objective. Wireless Services could turn its attention to a structured analysis of its supply chain. The supply chain at the time was typical of supply chains that grow without benefit of conscious design. Most products were produced by outside Pacific Rim companies — and there were many of these. These, in turn, were supplied by several himdred component suppliers, also in Pacific Rim cmmtries. Products and raw materials entered the U.S. and were shipped to AT T manufacturing plants in Mexico. From there, finished products went to distribution centers in the U.S. These distribution centers then shipped product to retailers and other OEMs who used Wireless Services products.
