Cellular One

Cellular One is the trademarked brand name used by several cellular service providers in the United States and Bermuda. The brand was sold to Trilogy Partners by AT&T in 2008 shortly after AT&T had completed its acquisition of Dobson Communications. Cellular One was originally the trade name of one of the first mobile telephone service providers.

History

In 1977, the American Radio Telephone Service and Motorola formed Cellular One to offer services to the Baltimore/Washington, D.C., area. In 1984, cellular service began in the Baltimore/DC area.

The Baltimore/DC service, and the rights to the name Cellular One, were sold from Metromedia to Southwestern Bell in 1987. In 1989, Southwestern Bell Mobile Systems and McCaw Communications formed a partnership called Cellular One Group. In 1992, Vanguard Cellular Systems joined the group. In 1995, Cellular One opened up membership in the partnership to all A-side providers. Under the US AMPS allocation, A-side providers were independent wireless operators, while B-side providers were usually affiliates of the local landline telephone company. A new slogan was also developed, "Cellular One: Clear Across America", recognizing cellular's national reach, although there were very few national plans at this time. In 1995, Cellular One affiliates had over 5 million customers and affiliates' towers served approximately 69% of the US population. Also in 1995, SNET joined the partnership. Not all A-side carriers participated: most notably, L.A. Cellular, in the nation's second largest market, Los Angeles, never participated in Cellular One, and did not have agreements with Cellular One for some time. AT&T purchased McCaw Cellular in 1994; shortly thereafter, AT&T renamed the former McCaw providers "AT&T Wireless" and dropped out of the partnership. Western Wireless joined the partnership in 1999, and in 2001, the Cellular One group name became the sole property of Western Wireless.
