PRNewswire/ -- In 1983, a small crowd gathered in Chicago to launch the nation's first citywide cellular service. Today, 23 years later, another seminal event in wireless history is taking place here - the completion of Cingular's GSM (Global System for Mobile Communications) network integration. The network integration, which began shortly after the merger of Cingular Wireless and AT&T Wireless in October 2004, has dramatically improved call quality for Cingular customers throughout the nation. Cingular completed its GSM network integration by reusing existing assets, working closely with vendors, and minimizing site visits by technicians.

"With integration complete, we're now focused on quickly offering 3G services in all of the top metropolitan markets and surrounding areas," said Reynolds. "We want our customers to have a similar broadband experience whether they're in their homes, at work, or at the park. Staying connected to information is great - getting it anytime, anywhere and at lightening-fast speeds is priceless. "The UMTS/HSDPA network complements and supercharges Cingular's EDGE (Enhanced Data Rate for Global Evolution) network, available to more than 270 million people living and working in more than 13,000 cities and towns across the Untied States. Unlike some competitive services, all 3G services and features, such as Cingular Video, are also available on the company's EDGE network. Read Press Release
