Cingular is purchasing 3G equipment from Lucent for the high-speed wireless trial it plans to launch this summer in Atlanta.

The third generation services will include high-speed data and multimedia. Cingular said the trial will include its employees.

The UMTS (Universal Mobile Telecommunications System) trial will utilize spectrum Cingular already owns. Cingular said it will ultimately offer data at 14.4 megabits per second and will support Internet protocol (VoIP) services in the future.

“With this network, Cingular Wireless will be able to provide services such as high-speed downloads of film trailers, and video clips of sporting and entertainment events; mobile access to e-mail (including large attachments); and the ability to locate nearby services such as ATMs, restaurants or movie theaters,” the company said in a statement.

The trial will help Cingular “overcome technical challenges before pursuing broader deployments,” said Kris Rinne, Cingular’s acting chief technical officer.

Lucent will provide an end-to-end mobile network, including wireless PC modem cards.
