Nortel, Optimus complete 3GPP voice calls

Nortel Networks Corp. and Optimus, a subsidiary of SonaeCom and France Telecom SA, say they have completed live voice calls using the Universal Mobile Telecommunications System Third Generation Partnership Project wireless standard.

The calls were made from Porto, Northern Portugal, using commercial 3GPP-compliant UMTS equipment from Nortel. The Nortel equipment used included Internet base transceiver stations and an Internet radio network controller.

Previously, Nortel announced: a multivendor 3GPP test voice call with Mercury in Korea; completion of UMTS voice calls on a national network with Airtel in Spain; and UMTS voice and data calls in the U.K. with BT Cellnet.

3GPP is a project that began in December 1998 to produce technical specifications and reports for a third generation mobile system. Later, the scope of the project was changed to include the maintenance and development of GSM.
